What happens to your hair before and after a bleach bath

before and after

In order for us to learn how a bleach bath will affect your hair, it’s important to consider how many bleach baths you’re going to do and what ingredients you’ll use in the mixture.

  • If you use coconut oil in your mix, you can minimize the damage from peroxide by 45% in your hair. And that is no small number.
  • If you use a hydrating shampoo with keratin, you’ll reduce the damage by over 70%. That’s another number that you can’t ignore.


 The more hydration you give your hair during the process, the less damage your hair is going to suffer.  

Now, what is your hair like before you start the bleach bath process? Because that will also affect your end result.

  • Is your hair dry?
  • If your hair is dry before the bleach bath, it will be prone to breaking after it.
  • Is it rough to the touch and dull in color? After the processing, it will be totally dry.
  • If you have a lot of frizz before, you’re going to have double the frizz after.
  • If you have a lot of natural oils in your hair before, your hair is going to feel rougher afterward, will no grease.
  • If your hair feels hard or crunchy now, you’re going to have a lot more frizz after.


What can you do then?

  • If your hair is dry, rough or frizzy, use coconut oil on your hair 24 hours before you do the bleach bath and leave it in your hair for the full 24 hours.
  • If your hair is greasy, don’t wash it for 48 hours before the bath, and three hours before you’re going to do the treatment, wet your hair without using either shampoo or conditioner, then comb through it to distribute your hair’s natural oils to protect your hair fiber.


Once you’ve finished with the process, it’s also important to do a certain aftercare routine

  • Use coconut oil on your hair, without applying it to your roots, and leave it in for 4 hours
  • Use micellar water on your hair every two hours to moisturize it
  • Use a reparative mask once a week
  • Use an anti-frizz serum to hydrate your hair 


 You need to protect your hair fiber before, during and after the bleach bath, especially if your hair is dry or damaged.  

Now that we’ve consider your hair health before and after the bleach bath, let’s get to the heart of the matter: the color. Because, after all, if you want to do a bleach bath, it’s because you’re looking to lighten your hair.


What to expect after a bleach bath in terms of color

A bleach bath lightens your hair ½ to 2 shades, depending on what volume peroxide you use.

  • If you use a 10 volume peroxide, your hair will lighten ½ to 1 shade
  • If you use a 20 volume peroxide, your hair will lighten 1-2 shades

Let’s have a look at how your color will change in each color group.


Dark hair

  • If your hair is a black 1 now, after the color bath, it will turn into a very dark brown 2 or a dark brown 3.
  • If it’s a dark brown 3, it will turn into a brown 4 or a light brown 5.
  • If it’s a brown 4, it will turn into a light brown 5 or a dark blonde 6.


Medium hair

  • If your hair is a light brown 5 right now, it will turn into a dark blonde 6 or a blonde 7.
  • If it’s a dark blonde 6, it will turn into a blonde 7 or a light blonde 8.
  • If it’s a blonde 7, it will turn into a light blonde 8 or a lighter blonde 9.


Light hair

  • If your hair is a light blonde 8 now, it will turn into a lighter blonde 9 or the lightest blonde 10.
  • If your hair is a lighter blonde 9, it will turn into the lightest blonde 10.


As you can see, it’s a process that follows a certain logic in terms of how many shades your hair will lighten, unlike a traditional bleach job, which can lighten your hair up to four shades in one go.

Use this guide to know how many times you’ll need to do a bleach bath to get to the color you’re looking for and avoid stressing your hair more than necessary.



A bleach bath will always have a very clear before and after, both in terms of your hair health and your hair color.

  • If we’re talking about hair health, you should always start with healthy hair, because if not, you can end up with dry, weak hair prone to breaking.
  • And when it comes to color, you should decide how many shades you want to lighten your hair, because that will determine which volume of peroxide you want to use.


But remember: Although a bleach bath is less aggressive than a traditional bleach job, it will have consequences both on your hair and in your life. So, take the necessary precautions to keep your lively, beautiful hair that way.
