Best Blue Black Hair Dye: 15 Easy-to-Apply Hair Colors for Darker Results

The blend of dark black with blue looks quite flattering and mysterious. You can only choose this color if you have a daring side you want to flaunt. On top of that, every turn of your blue black head catches the light. For that matter, what is the best blue black hair dye?

There are many ways to combine blue colors. These colors include navy blue, royal blue, midnight blue, etc. And they fuse quite well with black hair dyes. Keep in mind that lighter blue shades of blue and black version look better on darker skin tones. As for the darker blue black version, it looks very flattering on a lighter or pale complexion.

Whatever the case, here are the top 15 hair dyes you might want to take into some serious consideration.

Why Choose Blue Black Combination Color for Your Hair?

Best Blue Black Hair Dye

It’s a blend of blue and black shades. And this combination merges together for creating a mysterious, flattering midnight blue effect. Some women with black hair even go for just blue highlights.

Blue-black is actually a very daring choice to make. So those who like to experiment may actually end up loving the color. And even more so when your dyed hair catches the light of the sun and looks even more attractive.

And the most popular reason why women and men go for blue and black combination is that there are many variations of the color. The lighter versions are the best for both fair and dark skin tones. While the darker options are perfect for pale to light complexions.

Different Types of Hair Dye

No matter the hair color, hair dyes come in a variety of types. So here are the most common ones used across the globe

Permanent Hair Dye

Just as the name suggests, permanent dyes transform the shade of your hair permanently. Permanent hair dye and a developer opens up your hair cuticles. And then add the color deep inside those cuticles. After that, the cuticle reseals. And that’s how the color prevents from escaping.

Now you should also know that the permanent kind doesn’t fade away over time. That means there’s a noticeable difference between your new hair growth and your colored hair.

So for how long does it last? The answer is indefinitely since permanent dyes alter the natural hair color structure.

Demi-Permanent Hair Dye

This formula contains low ammonia combined with a low-volume developer. And what demi-permanent does is opens your hair cuticles to allow the dye to enter slightly into your hair shaft. It’s a sheer formula that changes your hair tone or darkens your hair color. While also adding shine.

But you cannot expect demi-permanent hair dyes to cover greys or lighten or lift your hair. That is something only permanent hair dyes do so far. This particular version though starts to fade gradually after 12-24 shampoos.

Semi-Permanent Hair Dye

Needless to say, it’s gentle without any ammonia. And semi-permanent requires no developer. It deposits the color over the surface of your hair. Much like a subtle sheer coating. That implies semi-permanent, unlike permanent and demi-permanent, doesn’t penetrate your hair shaft. Yet it has the ability to alter the hair tone.

Once again, this does not cover greys or change/lighten the hair color. And it begins fading after only 4-12 shampoo washes.

Temporary Hair Dye

The name suggests temporary, and that’s exactly what you get. This type of hair dye changes your hair color immediately but temporarily. What it does is coats your hair with the color of your choice. And only one shampoo wash is required to get rid of the temporary hair color.

The Most Popular Blue Black Hairstyles 2020

Deep Blue Bob for Short Hair

Deep Blue Bob for Short Hair

No doubt, this is a very common hairstyle for women. In fact, many women who choose the blue and black shade get a bob cut.

It’s a chin-length, angular hairstyle tinged with beautiful blue. An ideal way to make a statement if you ask me. You can even curl your hair strands to make your hair look messy.

Deep Blue Pixie for Short Hair

Here’s another common hairstyle for those who prefer short hair. The blend of black and deep blue is very bold to carry. So why not make it even bolder with a groovy pixie cut?

Agreed that it’s a super-short hairstyle. But that’s what makes it look so cool and chic.

Peek-A-Boo Blue for Medium-Length Hair

A vivid color in the form of bright blue highlights under your black medium-length top layers does indeed create a fashionable look. It also appears to be very fun because of all the peek-a-boo blue effect.

And the best part is that you can choose to keep it minimal with just a few highlighted strands of blue.

Midnight Tousled Layers for Long Hair

To be honest, this is a very popular hairstyle among women with long hair. A midnight blue tint on top of black or dark hair adds more depth to the long layers. Your hair is bound to look more enriched. And that’s the beauty of midnight blue hair dye.

Ombre Shine for Long Hair

Do you know that the blue black combination comes in a broad range of shades? So why limit yourself, right? So it’s time to have some fun by choosing an ombre look. This blends darker, more purple-tinted blue with brighter, lighter blue. And all of these gradient fills look the most attractive only on long hair.

Choosing a Good Blue Black Hair Dye

It goes without saying that hair is very sensitive and highly prone to damage, right? No wonder so much care and caution go into picking the right hair care and beauty products. When you pick the wrong or a low-quality dye, what you’re doing is inviting hair damage and destruction. So here’s how you can avert such a tragedy…


The majority of hair dyes are packed with chemicals. But that doesn’t mean you can’t find more natural and safer alternatives. These include ammonia-free formulas. Many blue black hair dyes I’ve reviewed contain natural ingredients without any amount of ammonia and even alcohol and hydrogen peroxide in them.

Non-Drip Formulas

The whole experience turns sour when there’s hair color dripping down your neck and face and staining these parts of your body. So make sure that the hair dye manufacturer uses the term “non-drip” somewhere in their product description.

The hair color should also be easy to apply at home without creating a lot of mess.

Permanent or Semi-Permanent?

Now the answer depends entirely on your personal preferences. Semi-permanent blue black hair lasts for not more than 15-20 shampoos. As for the permanent version, it stays for as long as 8 whole weeks. And obviously, the latter is more fade-defying or fade-resistant.

Conditioners Built-In or Included

More often than not, hair coloring kits include the dye and conditioner. Sometimes both are blended. And sometimes, they’re two different products. Either way, make sure the conditioner is made using natural moisturizers like coconut oil, olive oil, avocado oil, and/or shea oil. Such ingredients add extra shine and nourish your hair post-dyeing.

Your Current Hair Color

The rule of thumb is to choose blue black if your natural hair color is black or a darker shade. But what if you have lighter-colored or blonde hair? In that case, first dye your hair a darker hue and then apply blue black.

Most professionals recommend choosing a dye color that’s at least a shade or two darker or lighter than your natural hair color. This way maintenance becomes easier. And your hair dye looks more natural as well.

Your Natural Skin Tone

Choosing a dye based on your natural complexion is very important. Otherwise, you can end up looking sickly and pale. Instead of your hair looking more vibrant.

Is your skin tone warm or cool? One way to determine this is by looking at your veins in the wrist. If they’re more green, then your skin tone is warm. And if they’re blue-ish, then your complexion is cool.

So for a naturally warm skin tone, you ought to go for warmer shades of blue and black, or any other hair color. This also applies to those with a golden or olive complexion. As for cooler complexions, select cooler hues of blue.

Your Natural Face Shape

If we’re taking your natural hair color and skin tone into account, then the shape of your face also matters. It has an impact on your haircut as well, not just the hair color.

Those with a narrower face structure should choose a blend of light and dark. Lighter hair along the sides of the face while the darker shade is on top. Such a blend makes the face look fuller.

What about if you have a wider or rounded face? Then go in the opposite direction. Darker colors along the sides and lighter shades on top. This, no doubt, makes the face look longer.

Your Natural Hair Texture

Not all hair texture is the same, correct? So if you have coarse hair, then go for dark shades of blue as they make the hair look moisturized and healthier. Don’t opt for lighter colors because they might end up drying out the hair because of more light reflection.

And for smooth hair, all options are great. But that’s not the case with a porous hair texture. In that case, keep away from pastel or blonde colors. Therefore, blue black ranks as the most ideal.

Harmful Ingredients to Avoid

Many permanent hair dyes use a combination of ammonia, p-phenylenediamine, and hydrogen peroxide. Now just because these dye chemicals are so commonly added to the formulas doesn’t mean they’re safe. All three are associated with plenty of negative effects in terms of health.

Ammonia is a potential disruptor of the endocrine system. And it’s also an asthma and respiratory irritant. As for p-phenylenediamine, it’s connection with blood and liver toxicity, skin irritation, allergies, and birth defects is not uncommon. Then comes hydrogen peroxide that can cause eye, lung, and skin irritation.

Then there are dyes equipped with neurotoxin as well. And this particular toxin is associated with birth defects, allergies, and pregnancy loss. Then comes the chemical resorcinol, which also causes endocrine disruption.

So make sure you choose a hair dye that’s more on the natural or organic side.


There’s no point or sense in buying a hair dye based on how expensive it is. Because even expensive options can be cheap in terms of quality. Therefore, price is no deciding factor here.

Instead, prioritize the dye strength against your hair condition. Focus more on what variation of blue-black you want to pick. And then find that particular version within your budget.

3. L’Oreal Paris Superior Preference Hair Color 2BL Black Sapphire

 L’Oreal Paris Superior Preference Hair Color 2BL Black Sapphire

Is this really the Superior Preference? By all means! And that’s because the brand is none other than L’Oreal Paris. This permanent hair shade delivers extraordinary luminosity and shine that lasts for a very long time.

But the thing that makes the hair color a “superior preference” is the combination of shine system and fade-defying color. The former consists of a UV filter, Vitamin E antioxidants, and golden camelina oil. It’s what makes your hair silky smooth. Then the fade-defying action takes place for almost 8 weeks.

L’Oreal’s ammonia-free 2B Blue Black Crème Gloss Hair Color enhances the natural shade of your hair. It counters dullness simply by making your hair look glossy and shiny.

In the formula, there’s pomegranate and royal jelly. Ever heard of such a combination in hair colors before? L’Oreal decided to add these two extraordinary ingredients for sealing in the glossy color. They leave your hair looking shiny and feeling silky smooth.

In the end, I would just like to say that the blue black shade looks stunning. Even the blue tint that stays in your hair for at least a week!

5. Clairol Nice’N Easy Hair Color 2BB Blue Black

Clairol Nice’N Easy Hair Color 2BB Blue Black

You know you can create professional, salon-quality tones and highlights in a single, simple step here. That’s the beauty of Clairol’s Color Blend technology. This Nice’N Easy Hair Color covers all your grays with the help of complementary highlights as well as lowlights.

The permanent 2BB Blue Black shade lasts for 8 whole weeks. It’s equipped with ColorSeal Conditioning Gloss for locking in the intense shine and beautiful color.

Some of you might cherish the fact that the formula is gentle and doesn’t give rise to any allergies. The revolutionary hair dye ingredient, ME+ molecule is used. So those allergic to hair dyes can rest assured knowing that this special formula doesn’t cause negative reactions. At the same time, it doesn’t compromise the results.

The delicate floral scent is just like a cherry on top of the cake. And in terms of application, you’re bound to appreciate the non-drip formula. It stays on the hair and doesn’t run down your neck. And you’ll be nothing but happy with the results too!

6. Clairol Natural Instincts Crema Keratina Hair Color 2BB Blue Black

Clairol Natural Instincts Crema Keratina Hair Color 2BB Blue Black

I like the word “keratina” used in the product title. When it comes to hair, keratin plays a major role. What is does is smooth down cells that overlap for forming hair strands. Hair cuticles absorb keratin to look glossy and full. Keratin is also very effective at reducing the frizz of curly hair. It makes your hair look straight and it also makes the task of styling hair easier.

So it’s nothing but a huge advantage that the current blue black hair dye is infused with keratin. It’s a non-permanent, ammonia-free formula that comes with a conditioner enriched with coconut oil. Leave it on for just 20 minutes and then rinse your hair, which is not such a time-consuming or annoying task by the way. And the results come out quite dark.

Post-application you can apply the conditioner for some much-needed hydration. The coconut oil in here smoothens all frizz and coarseness. So your blue black hair feels shiny and silky.

Rich color, great coverage, and smooth, super-healthy hair texture; that’s the kind of results I was talking about earlier.

7. Vidal Sassoon London Luxe 1BB Midnight Muse Blue

Vidal Sassoon London Luxe 1BB Midnight Muse Blue

The Sassoon London Luxe collection by Vidal consists of many ultra-vibrant, fashion-forward shades. And each color is crafted keeping salon expertise in mind. You get 8 whole weeks of professional-quality hair color. Every shade is blended for calibrating the right combination of pigments. The same can be said about the 1BB Midnight Muse Blue.

So if you’re daring enough to try a midnight blue hair dye on black hair, this should be your go-to choice. It covers all your grays, no doubt. And, quite surprisingly, the shade lasts for a much longer time than expected.

 If you ask me, the hair dye gives you the perfect results that aren’t too dark nor are they too light. It doesn’t grab, which is good news if you don’t want the color to look overpoweringly strong. And the hair color also produces a well-balanced shade. Even the application part of the job is drip-free, thus mess-free.

8. John Frieda Precision Foam Colour Blue Black 2A

John Frieda Precision Foam Colour Blue Black 2A

There are many things that stand out in the case of this Blue Black 2A Precision Foam Colour. The first is that John Freida has included foam technology for delivering salon-grade results. Speaking of results, they’re as natural-looking as you’d like them to be. And achieving them at home is very quick and easy just so you know.

No stains, no drips, no fuss. Just gorgeous blue black hair from each and every angle! The tone is simply perfect and can pass off as natural. It has a very beautiful blue tint to it and this tint lasts for quite a few months.

The hair dye penetrates every strand to provide deep color saturation along with complete gray coverage. Obviously, you get a nourishing after-color conditioner for sealing in the dye and providing longer-lasting richness. So you and your hair are all set!

9. Goldwell Topchic Hair Color 2A Blue Black

Goldwell Topchic Hair Color 2A Blue Black

Would you believe me if I told you that this 2A Blue Black Hair Color is infused with pantheon and hydrolyzed wheat protein? Well, I think you should because they’re a part of the ingredients list of this Goldwell Topchic creation. What hydrolyzed wheat protein and pantheon do is add immense shine and strength to your hair.

The formulation also consists of patented Color Link technology. This allows the color molecules of the hair dye to properly link together. On top of that, the penetration system of the special formula makes sure pigment distribution is well-balanced. Meaning the color reaches from your scalp to the ends of your every hair.

Speaking of root-to-tip coverage, your gray hair areas don’t stand a chance. So, along with this great coverage, you’ll also appreciate the exceptional shine and gentle quality of the hair dye.

One last piece of great news is that the blue black shade even fades very well. So you don’t have to worry about the fading part making your hair look dull or any less gorgeous.

10. Adore Semi-Permanent Haircolor #130 Blue Black

Adore Semi-Permanent Haircolor #130 Blue Black

This Adore Blue Black Semi-Permanent Haircolor contains zero ammonia, hydrogen peroxide, and alcohol. So if that’s your concern, then the road is all-clear here. This means you can enjoy vibrant bursts of luxurious hair color without damaging your hair.

The #130 Blue Black deposits natural color while also providing resilient shine. So there’s no chance your hair is going to be in a disappointing condition post-application. The formula contains natural ingredients that offer richness in terms of color and hair quality.

The shine-enhancing and hair-softening capacities are pretty strong here. And that’s what I like the most because not all hair dyes have the ability to deliver such results.

But the best part is the absence of any amount of ammonia, peroxide, and alcohol. Meaning the hair color is non-damaging. The perfect solution for keeping the shade fresh, minus potential damage.

11. SoftSheen-Carson Permanent Hair Color Midnight Blue 382

SoftSheen-Carson Permanent Hair Color Midnight Blue 382

The Midnight Blue 382 is a part of the 19 shades made by SoftSheen-Carson. And all of them are specially designed for protecting your natural hair at the time of coloring. So the results come out luxurious, shiny, long-lasting, and silky soft.

The conditioning formula of this permanent hair color wraps your every strand for protecting it against damage and dryness. It’s infused with fruit oils like olive oil, shea oil, and avocado oil. So deep, intense nourishment is a part of the roots and the tips. They lock in all the shine for illuminating color.

The brand is known to manufacture some of the best hair products. This includes fade-resistant and permanent dyes like the current one along with even shampoo-in, spray and conditioning color options.

Let me also point out that you’re looking at a dye specifically crafted for complementing African American hair. After all, SoftSheen Carson’s consumer base is mostly women of African descent.

12. Bigen Permanent Powder Hair Color 88 Blue Black

Bigen Permanent Powder Hair Color 88 Blue Black

I’m going to start by stating that the powdered hair color is very easy to apply. The formula is incredibly gentle on the hair. Meaning it does indeed leave your hair feeling soft post-application. The permanent hair color is much less harmful in comparison to most commercial hair-damaging and drying dyes out there.

The blue black shade covers up all your gray tones. And this color doesn’t even fade that quickly. But still, the natural and non-damaging aspect of the hair color is what you might value the most. The formulation is also highly pigmented.

No stains to deal with, which is great news. It doesn’t even stain your scalp by the way. Washing the hair 3 times also doesn’t cause the color to fade. So if that’s not a favorable outcome, then I don’t know what is.

To top it off, the hair dye produces a dark, deep color that covers the most stubborn gray hair. So you’re very likely to keep coming back for more.

13. ION Midnight Blue Black Permanent Crème Hair Color

ION Midnight Blue Black Permanent Crème Hair Color

Let’s get into the description of the ION Midnight Blue Black Hair Color right away. The formula uses pure ionic micro-pigments. These deliver a more intense, deeper color. The combination of saturated matte dyes and warm pastel pigments is what produces the melting of the shade.

ION here has created a product using the highest quality exotic and natural ingredients packed with high-tech and powerful compounds. So the color looks exquisite and brilliant with complete gray coverage.

What the microscopic molecules also do is oxidize slower, thus making way for deeper penetration for fade-resistant, long-lasting color.

Furthermore, the formula is PPD-free. And infused with argan oil, hyaluronic acid, and pequi oil. There are botanicals in here for nourishing and strengthening your hair from deep within. Not many hair dyes can do that you know. So if this is the kind of stuff you want to apply on your hair, instead of chemical-laden, damaging hair colors, then go for it.

14. L’Oreal Paris Healthy Look Crème Gloss #2B Blue Black

L’Oreal Paris Healthy Look Crème Gloss #2B Blue Black

Here’s another ammonia-free hair color by L’Oreal Paris. The previous option lasts for 15 shampoos. So if that seems like a small number to you, then how about a hair dye that lasts through 28-30 shampoos? Sound good?

No doubt, this Crème Gloss adds a beautiful shine to your hair. One that doesn’t dull anytime soon or start to look fake. The formula contains deep conditioners for softly blending away your gray hair. And the fact that it’s ammonia-free says a lot about keeping the health and condition of your hair intact.

Now let me tell you something that maybe you’re waiting to hear. In sunlight, the shade of your hair appears to be more naturally and gorgeously blue than black. If you ask me, it’s a great hair color that you can rely on to produce a shade that doesn’t fade all that quickly.

15. Schwarzkopf Color Ultime Hair Color Cream

Schwarzkopf Color Ultime Hair Color Cream

The beauty of Color Ultime by Schwarzkopf is that it delivers professional, salon-quality results. This version of blue-black comes in the form of sapphire black.

Let me bring to your attention that Schwarzkopf is one of the very few brands that even those sensitive to hair dyes can use safely. Meaning no amount of itchy scabs take control every time you decide to color your hair. The whole experience is itch-free, which means definitely worth a shot.

As for the color, it lasts for a very, very long time. You can refresh the shade once in every 3 months. That’s long enough considering how some other options offer way less. Even when you want to hide plenty of greys, this hair color doesn’t disappoint. Covering greys completely is the mark of a high-quality hair color.

The color intensity is vivid and the advanced formula is fade-resistant. On top of that, your hair starts to look incredibly shiny. And if you don’t like sapphire black, Schwarzkopf offers many different shades to choose from. This includes iconic blonde, flaming red, magnificent black, deep brunette, and more.

How to Dye Hair Blue Black Based On Your Natural Hair Color

Obviously there’s a blue and black combination for different natural hair colors. I mean you cannot expect just every shade of blue to complement dark hair, red hair, blonde hair, etc. at the same time. That said, here’s the breakdown

Blonde Hair

This could be light blond or dark blond, right? The results are not going to be the same in both cases. So for light blond, first you may have to dye your hair a darker color and then apply the blue black dye.

Red Hair

Much like blonde hair, this shade also requires more maintenance. But, on the contrary, you first need to lighten your natural red locks to produce orange undertones. And then apply your choice of blue dye. Although you might require more blue than black in this case.

Dark Hair

The blue black blend suits dark hair the most, that’s for sure. So for more effective results, you can pre-lighten the locks with your favorite blue shade.

Brunette Hair

This means your natural hair color is a medium version of the brown shade, right? So just apply your blue black color over your brunette hair.

But in case your natural color is warm brown, the result might look a little green. So go ahead and add some purple to that for reducing the brown warmth.

How to Get Blue Black Hair?

It’s not as simple as applying the blue black or just blue hair color for achieving the desired results. You might think it is. But the truth of the matter is that you have to bleach your hair and then dye it. Particularly if you want that daring hair shade to last for a longer time!

Start by Bleaching Your Hair

I highly recommend bleaching first if your hair color is dark. Only then can you expect the blue black shade to appear accurately. You have to lighten your hair before you dye it. This means you can skip bleaching if your current hair color is already light.

When bleaching, make sure to include aluminum foil for balayage. The aluminum foil keeps the color from getting into your natural hair.

Also, don’t forget to condition your hair deeply. Moisturized and well-nourished hair always produce better results. Keep that in mind.

Then Dye Your Hair

The first step here involves protecting your skin. You don’t want the hair dye to come in direct contact with the skin. So to avoid that, apply a little bit of petroleum jelly to the scalp. It eliminates the possibility of tainting and staining.

Needless to say, use gloves. Also, include an apron and make sure to wear old clothes for preventing stains.

Every hair dye comes with its own set of instructions. So follow them correctly. If you wish to apply the hair color on your head completely, then start at the end and work your way up to the roots.

Sectioning parts of the hair with the help of clips is also a very useful method. But for highlighting, use foiling paper to keep the rest of the hair away from the color.

Once you apply the dye, cover your hair with a shower cap. Leave the color for the time mentioned in the instructions. Once that time lapses, rinse your hair with cold water. I say cold water because it locks in all the color. Then shampoo plus condition your hair. And that’s about it.

How to Maintain Blue Black Hair for Longer?

Hair, once colored, can start to look dry and unkempt. But that’s only if you don’t put in extra effort and time to care for it. And by extra, I mean washing your hair twice a week only. Keep in mind that more frequent washing opens the door to faster fading of the color.

Whenever you wash, make sure you’re using a shampoo and conditioner specifically created for damaged or colored hair. Only then can you expect proper nourishment and care. Speaking of conditioner, deep conditioning goes a long way when it comes to looking after dyed hair. Take your head showers using cold water as it locks in hair nutrients and moisture.

As you already know permanent hair coloring formulas are packed with hydrogen peroxide or ammonia. And these chemicals tend to damage or dry out your hair follicles. So all the more reason for deep conditioning.

And lastly, avoid a lot of direct sun exposure. You can also apply hair products equipped with UV protection.

Frequently Asked Questions

How Long Does Hair Dye Last?

The thing about permanent hair dyes you probably don’t know is that they are formed by oxidation. This process involves oxidizers like ammonia and hydrogen peroxide. These are usually combined with the dyeing/coloring agent. But there are ammonia-free and peroxide-free hair dyes too these days.

You should also know that permanent colors don’t require frequent applications. Plus, they appear more natural as well in comparison to other types of hair dyes. And that’s because chemicals in permanent hair colors tend to be stronger.

As for answering the question, how long does hair dye last? Around 6-8 weeks, in the case of permanent hair color. Semi-permanent, on the other hand, doesn’t last for more than a maximum of 15 hair washes.

Factors like sun exposure accelerate the fading of hair dyes just by the way.

Is Blue Black A Natural Hair Color?

There’s no chance you or anyone is born with natural blue and black hair color combination. So the answer is NO, blue black is not a natural hair color. The natural color of your hair is actually based on the melanin (pigment) present within the hair.

If you have a lot of eumelanin, which is a type of melanin, then your natural hair color is brown or black. There’s no type of melanin that produces blue hair.

Should I Wash My Hair Prior to Dyeing It?

The answer is NO. Avoid washing your hair for a whole day before coloring. And here’s why.

Your scalp and hair produce natural oils, right? And these oils are very beneficial in the sense that they initiate faster color absorption. At the same time, the natural oils prevent the chemicals present in hair dyes from damaging your scalp and hair. Such protection comes in handy especially when richer, darker shades are involved.

What Role Does My Natural Hair Color Play During the Dyeing Process?

No doubt, color blending is tricky. But here’s the rule of thumb. The darker your natural hair shade, the darker the blue black or any other color hair dye results. As for light or blonde hair, you might have to go through some coloring phases for making sure your dyed hair doesn’t look uneven or discolored.

Does Swimming Affect Colored Hair?

It goes without saying that swimming pool chlorine has an impact on dyed hair. It dulls the shine of hair color. But this is something that you can prevent simply by wearing a swimming cap.

Another thing you can do is wet your hair before entering the pool. This practice keeps chlorine from getting absorbed into your hair and reducing the amount of damage it causes.

What About Heat Styling Colored Hair?

What if you’re used to styling your hair very often? Does that mean you cannot use your curling iron or hair straightener once you dye your hair blue black? There’s no denying that heat pulls off hair color from the cuticles. And this paves the way for quicker fading. But you can make the heat styling process less invasive simply by using the right heat protection hair styling products.

Can I Dye Red Hair Blue Black Color?

Let’s be honest here; both red and blue are bright colors. So the result might not look good. But if you still want to go ahead with dyeing your red hair blue black, then go for an intense blue variation. But first, you will have to decolorize your red hair. Meaning make them lighter so the blue shade can stand out.

You’ve Reached the End!

Every blue black hair dye I’ve reviewed does an excellent job of making your hair look shiny and lustrous. The colors are the perfect blend of blue and black. And most of them last for as long as 8 whole weeks. They offer complete gray hair coverage. And come with additional conditioners for nourishing, hydrating, and protecting your freshly dyed hair.

Almost every formula contains some or other ingredient that keeps your hair from getting damaged and looking dull. Such as olive oil, shea oil, avocado oil, coconut oil, etc. Some hair colors are also equipped with pomegranate and royal jelly for adding shine and smoothness.

You can go ammonia-free as well if you like. I mean there are plenty of ammonia-free choices at your disposal here.

As for getting access to information regarding hair dyes, I have discussed that too. So you have every reason to go blue black right away!
