  Are you dreaming about going blonde after black box dye?  


You can make your dream come true. It’s actually possible to turn black dyed hair blonde.

Therefore, you’ll have to bleach your hair.

As you may know, bleaching is a bumpy road. You should take it slowly to avoid crashing.


Also, I want to make something clear from the get-go. Black box dye is the same as professional black dye. It’s not lighter, and it doesn’t come off easily.

It takes the same time and effort to bleach your black colored hair blonde.


How many times will you bleach your black hair?


It’ll depend on the blonde you want to achieve. . Each bleaching session may lighten your hair up to four or five levels.

So, if you want to achieve dark blondes, you’ll have to go through three or four bleaching sessions. But if you want to achieve light blondes, you’ll most likely have to bleach your hair up to eight times.


These bleaching sessions cannot be done within a fortnight. Instead, you’ll have to wait at least three weeks between each session for your hair to regain moisture and nutrients.


I don’t mean that you should give up. I mean that you should prepare for the road you are about to start.

Have you heard about Camino de Santiago?


It’s a route in the north of Spain. Every year, hundreds of pilgrims travel from France to Galicia to reach the Santiago de Compostela Cathedral.

These pilgrims prepare all year long to walk this path, which takes them through mountainous, hard, and remote places.

If you want to turn your dyed black hair blonde, you’ll also have to prepare yourself along the way. And you must take a lot of patience and respect for your hair’s health.

I’m going to help you get ready for the road with a tip.


  Go to a salon to turn your black hair blonde.   That way, you won’t burn your hair.

So that you know what to expect along the way, I’ll tell you a bleaching plan that you can put into practice with your trusted colorist.

In this case, as a colorist,   I recommend your first goal is to reach blonde 7.   From that base, you’ll be able to continue lightening your hair more easily.

Of course, it all depends on the colorist’s experience and the products they use.


Nowadays, almost all salons use OLAPLEX and WELLAPLEX, They help bleach hair without damaging it.

Due to these products, colorists can bleach hair more than once a day. Higher volumes of a developer can even be used to save bleaching sessions.

If your colorist works with Olaplex or Wellaplex, you’ll probably achieve the lighter blondes in one or two sessions.


However, if your hair is damaged, frizzy, or dry, your colorist won’t be able to bleach your hair, even using Olaplex.

Otherwise, your hair may burn or break. Therefore:

  •   If your colorist evaluates your hair fiber and there is no significant damage,   he/she can apply Olaplex or Wellaplex products and accelerate bleaching.
  •   If your colorist evaluates your hair fiber and it is damaged or dry,   he/she will only be able to bleach your hair once every three weeks.


Here’s how to take care of your hair between each bleaching session.


How to care for black-colored hair while bleaching to blonde

On the way to blonde, and as your hair goes through different bleaching sessions, some unwanted colors will appear, such as orange or yellow.

To neutralize those unwanted tones, the colorist will apply a toner to your hair. Then, you’ll need to use a toning shampoo to keep your hair free of these strident colors.

  • If your hair is reddish, you should use green shampoo.
  • If your hair is orange, you should use blue shampoo.
  • If your hair is yellow, you should use purple shampoo.

You should use the toning shampoo once a week for five to seven minutes.


But let’s not forget the important thing. Bleaching causes loss of nutrients and moisture. So, you need to repair your hair after each session.

My advice is to use   natural oil masks,   such as coconut, flaxseed, avocado, or argan oil.

  • Apply ten drops of oil to your damp hair from roots to ends.
  • Massage your hair for some minutes.
  • Wrap your hair with a shower cap and leave the oil on for 20 minutes.
  • Rinse your hair with your usual shampoo and conditioner.


You should use these oil masks twice a week. This way, your hair will be stronger to face a new bleaching session.



Black is a dream that turns into a nightmare when you want to get it out of your hair. No dye neutralizes it and no simple process that removes it in one step.

Therefore, the only way to turn black hair blonde is to apply several bleaching sessions. And my professional advice is to go to a salon to avoid damaging your hair irreversibly.
