Relaxed hair with beautiful vibrant dye can be very fascinating and attractive. It can create a very refreshing and appealing look and change one’s overall appearance completely. Relaxing is a procedure that removes the natural curls of the hair and makes them straight by chemical processes. Dyeing your hair can also be a fun experiment that you can do with your hair to stand out from the crowd. But dyes also contain chemicals to get absorbed into your hair and give it beautiful vibrant colors.

Can I Dye My Hair Black After Relaxing It?

Yes! You can dye your hair black after relaxing it. However, there are certain considerations that you need to go through to dye your hair after relaxing and keep your hair as less damaged as possible.

Black dyes are made with the most persistent pigments. They work faster on the hair even if you have previously dyed hair. Since black hair needs less processing time, it will make your hair less damaged after the chemical processing of the relaxed hair. But you should also keep in mind that black pigments are very hard to get rid of.

So, if you do not like the black color afterward, you will have no option left. Bleaching your hair after relaxing and dyeing is extremely damageable which can lead to major hair fall and can burn out your hair. Also, black pigments are very strong and hard to remove, so multiple bleaching processes may be required to wash off the pigments completely.

And if you are sure of dyeing your hair black, then go for it. Make sure to dye your hair after the recommended time limit with the right hair dye and follow the aftercare routine that I have mentioned below.

It is recommended to wait at least 7 to 14 days to dye your hair after relaxing it. This waiting period helps you to recover from the chemical processing that is involved in the relaxing procedure. This time will allow your chemically treated weak hair to regain the strength and moisture of your hair.

Waiting for 2 weeks will also help your hair from further damage caused by the chemicals of the dyes. During this period, seek assistance from an expert to assess the condition of your hair. An expert can give you personalized advice on what approach will be best for your specific hair condition while being in good shape and health.

What Happens If I Dye My Hair Right After Relaxing?

If you dye your hair right after relaxing, it can severely affect your hair. Hence, it is not recommended to dye your hair immediately after relaxing. The relaxing process weakens the hair and makes your hair more fragile and vulnerable to other chemical treatments.

Hair dyeing is also a chemical treatment that can make your hair very dry and brittle if done right after relaxing. It can even lead your hair to burn out, extreme breakage, or hair loss.

Also, sometimes the chemical processing doesn’t even allow your hair to absorb the hair dye properly. It can make the hair color very unexpected and uneven which you might not like. So, try not to dye your hair black within two weeks.

There are already so many changes happening to your hair due to the chemicals of the relaxer. That’s why you must choose a black dye that respects the condition of your hair and is gentler and milder on your hair.

Make sure that the hair dye does not contain ammonia or resorcinol. If the dye does not have PPD, parabens, phthalates, and gluten, then that’s a plus. You should also check the ingredient list and choose the dye that has keratin, ginseng root extract, argan oil, or other natural nourishing ingredients.

Also, instead of doing permanent hair color, you should go for a semi-permanent or demi-permanent hair color after relaxing. These colors do not make any major chemical changes in the hair. They are absorbed into only the cortex of the hair making it less damaged.

Consideration Before Dying Your Hair Black After Relaxing

Even though you can dye your hair black after relaxation, there are certain things that you need to consider before taking the initiative to dye your hair. Such as:

1. Porosity and elasticity test

Before dyeing your hair after relaxing it, you need to go through a porosity and elastic check of your hair. If your hair lacks porosity or elasticity, your hair will be very prone to damage and breakage. So, you should never dye your hair after relaxing until the results are fine.

2. Correct volume of developers

If you want to dye your relaxed hair, you need to pick the correct volume of developers. Developers penetrate into the cuticle and bring your hair to a porous condition just like the relaxing process. If you have already relaxed your hair, you will need less dye and developers to apply it to your hair. If the box dye asks to add peroxide or developers, you need to reduce their amount to half and add half distilled or deionized water with that. You can find this water in supermarkets or use can also just use skimmed milk instead. You can also add some drops of liquid protein to the dye mix. Since relaxing breaks down the protein bond of your hair, it will give your hair extra strength and nourishment.

3. Ensure correct processing time

Normally, it takes less processing to dye your hair in relaxed hair than dyeing your hair in virgin hair. Virgin hair takes 30 to 40 minutes to process whereas relaxed hair takes 20-30 minutes. Although your hair type and texture are also responsible for determining the processing time, if you keep the dye longer than that, your hair will be overprocessed. To avoid overprocessing and damaging your hair, consult with an expert first.

4. Use appropriate products

After relaxing, use the appropriate products to rebuild the bonds of your hair and keep your hair firm and strong. You can find many bond-builders in the market that will help to make your hair soft, shiny, and moisturized. If you want to dye your hair after relaxing, you can mix these bond builders with the hair color. Make sure your bond builders are safe to use with the color. You can use the One Shot Bond Repair for this mixing with the hair dye. Also, remember to choose a color that has less harsh chemicals in it.
