Can You Dye Wet Hair?

Written by Arshiya Syeda

Can you dye wet hair? This has been a topic of debate every time, hasn’t it? Coloring your hair at home is simple – you just need to wash your hair and apply color to it. But this is not the case when you visit a salon. Instead, your hairstylist applies dye to dry hair. Hair dyes are designed with chemicals with different formulas. Depending on the formulations, some may work on dry hair while others work on wet hair. So, yes, you can dye wet hair. But there is a method to it. This article answers your questions and discusses how you can dye wet hair like a pro. Keep reading!

The Benefits Of Dyeing Hair While It Is Wet

Here is what happens if you dye wet hair:

  • Even Distribution: The moisture in the wet hair helps distribute the dye evenly. If you apply the same dye on dry hair, you need to pay more attention to each hair strand to ensure full coverage.
  • Wet Hair Is More Absorbent: Wet hair is porous as the hair cuticles open up, allowing better absorption of color pigments. As a result, the hair dye easily penetrates the hair shafts.
  • Quantity Of Dye: You need less quantity of dye for wet hair application. Hence, chemical damage is less as compared to coloring dry hair.

You can dye wet hair, but not all hair colors will work on wet hair. Permanent hair colors do not work on wet hair. Wondering why? Here is the answer.

Permanent Hair Color On Wet Hair: Why It Does Not Work

It is because of its chemical composition.

Permanent hair dyes contain ammonia and hydrogen peroxide. These chemicals work only on dry hair. They raise the hair cuticles to help the color pigment penetrate the hair shafts. In this process, the chemicals also strip the natural oils produced by the scalp.

If you wash your hair right before color application, you are stripping the natural oils, making it further susceptible to damage. And if you apply permanent hair dye on wet hair, the moisture will dilute the chemicals and prevent proper color absorption. This may result in uneven application and poor color payoff.

Pro Tip: Wash and condition your hair a day before the permanent dye job to minimize damage.

Now, the question is, what type of dyes work on wet hair? Find out in the next section.

Hair Dyes That Work Best On Wet Hair

Wet hair color application is best for those who are looking for temporary results. These dyes will produce the desired results on wet hair:

  • Semi-Permanent Dyes

Semi-permanent dyes do not contain peroxide and ammonia and are not affected by the moisture in your hair. They coat the hair to enhance the hair color. These dyes work well on wet hair as they do not penetrate the hair shaft to alter the hair color.

  • Demi-Permanent Dyes

Demi-permanent dyes contain some amount of ammonia, and, thus, penetrate the hair shafts. As the amount of ammonia is less than permanent dyes, they do not penetrate deeper into the shafts. The results are temporary but may last longer than semi-permanent dyes.

Other temporary dyes that are safe on your wet hair include pastel-hued, bright pink, and other highlighters. If you want to dye wet hair, you can either follow the manufacturer’s instructions on the packaging or these steps.

How To Dye Wet Hair

  • Rinse your hair with lukewarm water and squeeze the water with a towel.
  • The hair should be damp enough to dye.
  • Apply semi or demi-permanent hair dye to the area that you want to cover.
  • Cover your head with a shower cap and wait for 20 minutes.
  • Wash your hair with a color-safe shampoo.

Remember that semi-permanent hair dyes will fade with every wash. Some fade completely after one wash. These colors may stain your skin and clothes. Hence, secure them during application and washing. Here are answers to a few more questions that you might have.

Can You Dye Wet Hair After Bleaching?

No, you can not dye wet hair right after bleaching. Bleaching makes the hair strands dry, brittle, and prone to damage. Coloring your wet hair immediately after bleaching may cause further damage. It is better to wait for at least 10-15 days to color your hair post-bleaching.

Should You Dye Wet Hair At Home?

Yes, you can use a semi-permanent or demi-permanent hair dye to color your wet hair at home. It is easy to apply and less damaging than permanent hair dyes.

While dyeing your wet hair is less messy than a permanent dye job, it also has several disadvantages.

The Drawbacks Of Dyeing Wet Hair

The drawbacks of dyeing your hair while it is wet include:

  • Uneven Application: The moisture may help distribute the dye on your hair evenly, but the color application may not be precise, and some hair strands may not get dyed.
  • Water Dilutes The Dye: If your hair is dry and damaged, the strands will be porous and absorb more water, which could dilute the dye. Moreover, the shafts will be filled with water, with no room left for the dye to penetrate.
  • May Damage The Hair: Wet hair is weak and more vulnerable to damage. The natural oils provide additional protection to your dry hair strands, but they may not protect the hair under the water pressure.

The Takeaway

If you are looking for subtle and temporary results, you can dye your wet hair with temporary hair dyes. This process is ideal for those who want to experiment with colors but are afraid of the damaging effects of ammonia and hydrogen peroxide. However, if you are looking for long-term results, you have to apply hair dyes to dry hair.
