Dyeing hair that’s wet from sweat or washing it: Can you do it or better not to?

After doing exercise, it’s very likely that your hair is a bit damp or possibly even a bit wet, if you’ve sweated a lot.


That’s why,  if you’re planning to dye your hair after doing exercise, I recommend waiting until your hair dries. 

Another option is to dry it with a blow dryer. Once it’s dry, then you can dye it.


There are a lot of different opinions out there about if you can dye damp or wet hair or if you should actually wait until it’s fully dry.

At my salon, I usually do color washes or tone-on-tone dyes in the area of the salon with the sinks where we wash our clients’ hair. So, you can imagine for certain color treatments, hair can be damp or wet.

So, you’re probably asking yourself then: If Mimi does it at her salon, can I dye my hair if I was sweating? Why can’t I dye it if it’s wet?


Why you should dye your hair dry has to do with the permanence of the dye.

Imagine if I use the dye on my client’s wet hair and it starts running off, or even worse, it stains her clothes. That would happen because her hair, when it’s damp or wet, becomes slippery and the dye could start to drip.

Can you imagine what a disaster that would be?


And, if you’re not a professional stylist, you might end up with a dye job that’s not exactly even.

Like I told you before, if you sweat after a workout, your hair might be wetter in some parts, like along your scalp or near your sideburns, while it might be drier in other areas, like toward the ends. That difference could mean that the dye absorbs better or worse in certain parts, potentially causing your color to end up uneven.


Are you thinking about dyeing your gray hairs after sweating?

Don’t do it! Don’t dye your gray while your hair is sweaty! Wait until it dries naturally or if you’re in a rush, dry it with a blow dryer.


In order to make gray disappear, the dye product needs to sink deeply into your hair.

If your hair is wet in certain parts because of sweat, it might be that they only suck up a bit of the color and you aren’t able to dye them completely. If that happens, you’ll end up having wasted both time and money because you’ll have to repeat the process.


Situations where you can dye your hair when it’s damp

I told you before that in my salon we do hair color rinses and semi-permanent dye in the sink area.

This is because they are color jobs that allow for hair to be damp or wet

So, if you want to use a color rinse or a temporary dye, your hair can be damp, but it should be uniformly wet. You can’t use a dye if your hair is sweaty near your head and dry at the end.


Your hair should be totally wet or totally dry.  You should also make sure that the product you’re using is okay to use on wet hair. It’s extremely important to read the instructions and recommendations of the manufacturer closely  before applying the product.


To make this super clear:

  • If you’re dyeing your hair to cover gray, do it with dry hair, so you can be sure that the product won’t drip or dilute because of your sweat.
  • If you’re going to use semi-permanent or temporary dye, you can wet the rest of your hair and then use the product on wet hair. These kinds of products are superficial and don’t contain ammonia.


What should your hair be like before you dye it? Tips for dyeing your hair at home

It’s a good question if you’re thinking about dyeing your hair at home. If you’re going to a salon to dye your hair, you don’t have to worry so much about this because your stylist is going to worry about these things.

But, if you’re not able to get to the salon, there are a few things you should keep in mind before dyeing your hair.


  • It’s best if you haven’t just washed your hair.

Remember that the natural oils that your hair emits after 24 hours are essential for protecting your hair fiber during the dye process.

That doesn’t mean that you should let a week go by without washing your hair because then you’d actually suffer the opposite effect. The accumulated grease will make it so the dye can’t absorb correctly. Neither extreme is a good one, but with one to three days of “dirty” hair, you’ll be able to dye your hair without any risk.


  • You already know that you must dye gray hair when it’s dry, so, if you went to the gym and sweated, dry your hair before dyeing it.


  • Always read the manufacturer’s instructions and recommendations and do a color test before using the dye. It’s very important to do so at least 24 hours before using it.
