How to touch up roots on bleached hair at home (in 4 steps)

matching with the rest of the hair

  • To match the color of your roots and the rest of your bleached hair, you’ll only need to bleach your roots.
  • You should use the correct bleaching powder according to your base color and always choose 30 volume developer.
  • The process is very simple, and here I will explain it to you step by step.


Did your roots grow and look dark compared to the rest of your previously bleached hair color?


This is a natural process. After all, hair grows and, when it does, your base color will always show through.  The contrast between the growth and tone of your bleached hair can be quite unpleasant. 

It’s like going through life with a flag that reads, “Yes, I’ve bleached my hair.” No one wants to fly this kind of flag, right?


Don’t worry, because unifying the tone between the roots and the rest of your bleached hair is easier than you think.

Just apply the bleach mixture to the roots, and you’ll finally have an even color throughout your hair.


You’ll need two ingredients: bleaching powder and developer, which you can get at any hair salon or drug store.

But, can you use any kind of bleaching powder? What about developer? How much volume should it be?


Don’t worry, because there are answers for everything. So, if you want to match up the color of your bleached hair, stay with me because I’ll tell you:

  • How to prepare the mixture to unify the color of the roots and the rest of the bleached hair

How to prepare the bleaching mixture to unify the color of the roots and the rest of the hair

Before we get into the mix, I’d like to make two recommendations.

  • Firstly, don’t wash your hair for at least 48 hours before bleaching your roots. This way, your scalp will be more protected against the aggression of the chemicals in the bleaching mixture.
  • The second recommendation is that you always choose a well-ventilated place, as the aromas of the bleach mixture are usually quite strong and can make you dizzy or irritate your eyes and nostrils.


Now, let’s move on to the preparation of the bleaching mixture, which, as I mentioned earlier, is formed with bleaching powder and developer.


Bleaching powder

There are many types of bleaching powder: white, blue, extra lightening, or super blonde, and the only difference is the amount of ammonia they contain. The more ammonia, the greater the lightening power.

To know which one is best for you, you should carefully observe your natural hair color.

  • If your natural hair color is too dark, you can use the extra lightening powder or super blonde.
  • If your natural hair color is medium, you can use the blue bleaching powder.
  • If your natural hair color is light, you can use the white bleaching powder.


Once you know which bleaching powder to use, it’s time to choose the developer.


Peroxide or Developer

Developer is the component that lightens hair. There are several volumes of developer, from 10 to 100.

The higher volumes of developer, the greater the chemical reaction that will lighten the tone of your roots. So, you have to be very careful with the number of volumes you use.


  You should never use a developer of more than 30 volumes to bleach your roots. 

If you use a higher volume developer, it can generate such a strong chemical reaction that it will damage your hair to the point of breaking it.

What if your roots are too dark?


Unfortunately, it’s best to do two bleaching sessions than risk it using a 40 or 50-volume developer, which will only burn your hair. Literally.

Now that you have the perfect bleach mixture to touch up your roots and match up the color, put on your gloves, find a mirror, and an airy spot, and let’s take it one step at a time to bleach your roots.


Step by step to bleach the roots and match up the color

Once you have all the elements you can start bleaching your roots.


Step 1: Preparing your hair

Comb your hair carefully, so that no knots can hinder the process. You must comb it with a middle part so that your roots are exposed and you can see well where you should apply the bleaching mixture.

Put on your gloves and start preparing the mixture.


Step 2: Preparing the mixture

In a plastic container, mix the developer and bleaching powder, always in a   1 to 1 proportion. This means that if you use 50 ml of developer, you must use 50 ml of bleaching powder.  

Remember to always use plastic elements because metal inhibits the chemical reaction of the components.

Mix it very well so that the elements are integrated, until a creamy consistency is achieved.


Step 3: Application of the bleaching mixture

Start applying the mixture to your roots covering all the growth. You can use a dye brush or do it with your fingers, and always make sure you cover the growth and roots very well.


 Once you’ve finished applying the mixture, you should leave it on your hair for 30 minutes, not a minute longer,  because hair suffers greatly during bleaching and you risk it breaking or burning. That cannot be repaired.


Step 4: Rinse and dry

After the exposure time, rinse your hair with plenty of warm water, and use your regular shampoo and conditioner to moisturize your hair.

If you notice that your hair has become rough or dull, wash it again because you probably haven’t completely removed the bleach mixture.


Now look in the mirror. Is your color even? Are your roots the same shade as the rest of your bleached hair?


 Now it’s time to worry about the health of your hair. I suggest you wear moisturizing masks twice a week, as they will repair the damage caused by bleaching.  

There are many options on the market:

  • Masks with coconut or argan oil: they will give your hair back the softness and shine it lost during bleaching.
  • Masks with keratin: they will strengthen your hair in a structural way from the fiber.
  • Masks with silk: they will give your hair smoothness and you will notice that it will be much more docile when combing it



To match up the color of your roots with the rest of your bleached hair, just bleach them using a bleaching powder according to your base color and 30 volume developer.

If you want to reduce the damage caused by bleaching, you can add coconut oil to the bleaching mixture. This way your hair will be protected while the bleaching mixture does its process on your roots.

Are you ready to unify your color?
