Hair coloring is one of the easiest ways to change your look. However, changing your hair color can significantly affect your hair, especially if the color you choose is different from your natural hair color.

So, how long does it last? How to keep dye for as long as possible? It is a problem that you are very concerned about when dyeing your hair.

The following article will provide you with the most useful information about hair dyes' length of time. At the same time, we also share tips for maintaining dyed hair color.

Let's find out together!

How Long Does Hair Dye Last?

The dye won't last forever on your hair. As your hair grows, the dye loses its effect and intensity in your hair. Usually, hair dye will last for 4 to 6 weeks. Once the dye has faded, you will need to change the color or renew your hair.

However, the length of stay in the hair will not be the same for all dyes. Each dye will have different ingredients to meet your specific needs. Therefore, the length of time in the hair for each type will also be different, specifically:

Temporary hair dye

This is the kind of hair dye that will fade after 1-2 shampoos. The color only sticks to the surface and does not penetrate deeply into the hair. This hair dye can be considered a soft makeup layer for hair.

Permanent hair dye

Permanent hair dye turns your original hair color into a new color. Permanent hair dye contains an amount of ammonia combined with Aromatic and Phenol Amines. 

This compound lifts the hair cuticle and adds dye molecules. The peroxide comes in, and it breaks down the pigmentation that is naturally present in your hair. Peroxide dries out hair and contributes to hair damage.

Permanent dyes give hair the longest-lasting color because they cause chemical changes in the texture of the hair. Hair will continue to grow, and new hair growth will not be affected by the dye. 

How long does semi-permanent hair dye last? This dye stays in your hair for 4 to 6 weeks.

Semi-permanent hair dye

These dyes contain ammonia and hydrogen peroxide, which do not go as deep into the hair structure as permanent hair dyes. The hair color will maintain after about 10-20 washes. 

This is a fairly popular hair dye. The reason is that they are less harmful to the hair, keep the hair from turning back to its original color, and the cost of the product is quite competitive.

How Often Should You Dye Your Hair?

Ideally, you can visit a salon every 2 or 3 months to maintain the color. If you don't like the actual hair color that appears, you can go to the salon after 5 or 6 weeks to dye the roots. However, make sure you take proper care of your hair to avoid any damage.

Dye your hair after 5 or 6 weeks

You can also try dyeing a gradient-like ombre or highlight, so you don't have to dye it too often. If you want to dye your hair evenly, try colors that are about two to three tones lighter or darker than your natural hair color. A moderate change will help keep the color longer and safer.

You can use a hair protector like a serum before you heat styling or after going in the sun for a while, so you will minimize fading.

In the long run, you should also rest your hair for once. If you have dyed your hair over the years, consider giving your hair rest and recovery. You can try hydration treatments to speed up the hair recovery process.

How Long Should You Wash Your Hair After Dyeing?

How long does it take for the dye to penetrate into your hair?

Usually, it will take you from 1 hour or 2 hours, depending on the ability to color and adapt the hair. During this time, the hair dye color will be absorbed gradually, but it will still take many steps to get the correct color. 

It takes a lot of time and effort for the color to get into the hair. If you wash your hair right after dyeing it, you are purposely removing your hair color.

After 3 to 4 days, the coloring agent has had enough time to adhere to the hair strands. You can wash your hair at this time.

Some Other Notes To Help Dyed Hair Always Be Durable

How can you keep your hair as beautiful as just dyed and long-fading? The secret is here!

Do not wash your hair with hot water after dyeing your hair

Hot water can quickly penetrate the hair structure and wash away the ingredients that help stick to the hair color. So washing your hair with hot water means you're fading your hair color quickly.

Meanwhile, cold water makes hair soft and helps the dye’s ingredients stick more firmly to the hair. That's why no matter how cold the weather is when you first dye your hair, you should try to wash your hair with cold water.

Use dry shampoo

Dry shampoo not only improves flaky hair but also helps dyed hair last longer. Spray a little dry shampoo on the roots of your hair to absorb the oily layer. Your dyed hair will then look fresher without having to wash your hair too much.

Some dry shampoo products

Avoid products containing sulfate immediately

Sulfate is not suitable for your dyed hair. So, be careful when choosing your hair shampoo product. Sulfate will fade hair color very quickly.

Do not use shampoos labeled “Clarifying”

Products with the “Clarifying” label signify a range of deep cleansing shampoos and strong detergents. Using these products helps you get rid of dirt and bacteria on your hair but accidentally bleached your dyed hair faster than ever. Only use these products if you want to change your hair color or when you first dye your hair.

Use hair conditioner

If you have invested in intensive hair care, you cannot ignore the process of using a hair conditioner. Just use a hair treatment cream once a week for 30 minutes, and you will be able to have smooth and healthy shiny hair.

Don't dye your hair too often

Dyeing your hair too often will make your hair condition get worse. Try to dye your hair after 5-6 weeks if you want.

Trim as soon as your hair begins to deteriorate

If you have dyed hair and it has become scorched, you need to trim your hair and wait for the healthier hair to grow. 

The longer the split ends in your hair, the more severely damaged hair will be. You will need to get rid of the dry fork ends ultimately. Usually, it can be up to 10 centimeters or more. 

After trimming, you must take special care to repair damaged hair.
