Do you shampoo after dyeing hair with permanent dye?

  • Ideally, once the time you should leave the permanent hair dye in is up, rinse your hair with JUST water.
  • In other words, only use water to remove the dye residue from your hair. Then after 48 hours, wash your hair using a sulfate-free shampoo. This type of shampoo won’t remove the color from your hair.
  • Now if you need to shampoo your hair immediately because your hair feels dull or heavy, you MUST use a sulfate-free shampoo.
  • You can also use a toning shampoo to wash your hair after dyeing it if you see harsh colors. This type of shampoo doesn’t contain sulfates either.

I think I’ve been pretty clear. But, just in case, I’ll pass on my experience to you. As a professional hairdresser,  I’ll give you two tips on how to wash your hair after dyeing it with permanent hair dye. 

  •  After dyeing your hair with permanent dye, wash your hair with JUST water. Water will remove the excess dye from your hair.  You can also use the post-coloring product included in the dye kit.
  •   Wash it using a sulfate-free shampoo three days after dyeing your hair.   If you dyed your hair blonde, you can use toning shampoo to remove the harsh yellow or orange the dye left.


 What you shouldn’t do is wash your hair with just any shampoo, either the day you dye your hair or the following days.  Because many shampoos contain sulfates, detergents that remove the color deposited by the dye.

And, of course, you shouldn’t wash your hair with a clarifying shampoo after dyeing it either. Don’t use one either the same day you applied the dye or the days afterward. Clarifying shampoo removes all traces of hair products, dust, and dyes.

 If you wash your hair with a clarifying shampoo or a sulfate-free shampoo the same day you apply the dye, you’ll remove the color.


Let’s look at a few secrets of washing your hair after you dye it.

If you want the color to last longer, rinse hair dye using only water

When you apply permanent hair dye, the developer opens your hair cuticles so the color can penetrate and set inside your hair.

  After using the dye, the cleansing agents will remove a large part of the dye if you wash your hair with just any type of shampoo. Your hair color will fade. 


What should you do when rinsing out the dye?

  • Wet your hair.
  • Massage it for five minutes as you rinse it.
  • Let the lukewarm to cold water run through your hair until you finally see it crystal clear.
  • If the coloring kit contains a post-color treatment, use it. Leave it on your hair for a few minutes, then rinse it again using lukewarm to cold water.

Now, in my salon, there are two exceptions when I do use shampoo to rinse dye out.

  •  If I notice my client’s hair feels heavy and dull while I rinse the dye out , I wash their hair with a sulfate-free shampoo. First, I let the water run over the hair to remove the excess dye, and then I apply a few drops of sulfate-free shampoo to complete the job.
  •  If the dye leaves the client’s hair with harsh colors , I apply a toning shampoo. This doesn’t contain sulfates. However, it neutralizes the yellow or orange.


So far, we’ve talked about how to rinse out hair dye. What shampoo should you use a few days after dyeing your hair? That’s what I’ll talk about next.

What shampoo to use to wash your hair three days after dyeing it

Three days after coloring your hair, your hair cuticles will now be closed. But that doesn’t mean you can use just any shampoo.

You must consider the type and health of your hair and the color you used.


Let’s start with a simple premise.  The best shampoos for color-treated hair are those that don’t contain sulfates.  You can easily identify them because the labels always say “color-treated hair.”


If you wash your hair with a sulfate-free shampoo, the color will last longer. However, you can alternate another type of shampoo with sulfate-free shampoo to wash your dyed hair.

  •  If you dyed your hair blonde , alternate sulfate-free shampoo with a toning shampoo to neutralize harsh colors such as yellow or orange.
  •  If your colored hair is dry , alternate a moisturizing shampoo with the sulfate-free shampoo to help your hair fiber recover from the dye chemicals.
  •  You can also use dry shampoo up to twice a week .
  •  You can use the co-wash method with a sulfate-free conditioner. 



Just use water to rinse hair dye out. And three days later, wash your hair with a sulfate-free shampoo. This is the best way to make the color last longer.

You should also wash your hair less often. Allow 48 to 72 hours between washes to allow the oil from your scalp to moisturize your hair.
