  • To begin with, I’ll tell you what type of developer and bleach powder to use.
  • I’ll reveal the secrets to prepare and apply the bleach.
  • You won’t miss any detail on how to best protect your hair from the damaging effects of the bleach.


Here’s a summary of my top tips for mixing the bleach powder and developer to bleach your hair successfully.

We’ll go more in depth on each of them later.


Are you thinking about bleaching your hair?

Do you want to know how to mix bleach powder and developer?


You’ve come to the right place because I’ll tell you how to do it!

I’ve been a professional hairdresser for fifteen years, and I’ve bleached hundreds and hundreds of manes over the years.

I’ve also helped several friends and acquaintances who prefer to bleach their hair on their own.


Before I go any further, I want to highlight something important.

 Bleaching is a delicate process. I recommend you have done in a professional salon where an expert can carefully monitor the process. 


If you’re going to bleach your hair on your own, you should have some experience.

This comment in these DIY times doesn’t hurt.

We only have to look around to realize that suddenly, without having taken any specialized course, we all become experts.


 We’re experts in cooking, in hairdressing, in bleaching.  We’re even experts in breeding hairy frogs, one of the rarest frogs in the world.

Of course, if you think you’re a baking expert but your cake goes wrong, the worst would be to throw it away and start over.

Alternatively, order a cake from the nearest bakery.


However, if a bleaching process goes wrong, there’s no going back.

 You can’t bleach your hair again or order new hair unless you want to wear a wig. Bleaching can ruin and burn the hair. 

If you don’t believe me or think I’m exaggerating, look for videos on YouTube that’ll prove my point.


Having said that, I’m going to tell you my top tips for successful bleaching.

One of the main steps is to start with a well-done mix of bleach powder and developer.


  • For example, do you know about developer volumes?
  • Do you know if you should use cream developer or liquid developer?
  • Do you know for how long you have to mix the ingredients?
  • Do you know what consistency the mixture should have?

I’ll describe all this and more today.

Let’s get started!

Tip 1: You should use a 30-volume developer to bleach your hair without running the risk of burning it

correct ratio

To keep your hair safe, you should use a 30-volume developer at the most. It’ll help you lift your hair color by 3 to 4 levels in a single application.


As you can see, you don’t need to use more than 30 volumes.

 It’s better to have two bleaching sessions with an interval of 3 weeks, rather than using a higher volume developer. A 40-volume developer should only be used by professionals. 


The equation is simple: more volume = more chemical reaction = more hair damage.


Tip 2: Choose a creamy 30-volume developer to give your hair extra hydration during the process

dark and medium hair

There are several 30-volume developer options on the market. They could be liquid or creamy.

My advice is to choose a creamy developer. It’ll moisturize the hair cuticles to prevent them from breaking when the color is expelled.


Tip 3: You should only bleach your hair once a day. So, use white bleach powder

cover grays

Thre’re two types of bleach powder: blue and white. Although both have the same lightening power, they’re different:

  • Blue powder reacts better with aluminum (if you want to speed up the reaction) but can only be used once a day.
  • White powder reacts best with heat strips and can be applied up to twice a day.


Be careful!

To bleach your hair twice a day, you must have a lot of experience. Not even professionals do it to avoid damaging the hair irreversibly.


Tip 4: The consistency of the bleach should be creamy. You need to mix the exact proportions of developer and bleach powder

The bleach should have the same consistency as the conditioner. So, it should be creamy.


 To achieve that creamy consistency, you must mix two parts developer and one part bleach powder. 

Why do I say parts and not exact amounts?


Because the amounts may vary according to the length and quantity of your hair.

I advise you use the same container for both ingredients, for example, a plastic pastry measuring spoon.

Then, you’ll use two scoops of developer and one scoop of powder.  If you use a lid from some plastic container, you’ll use it twice for the developer and once for the bleach powder. 


What happens if the mixture is not creamy? You can always fix it.

  • If the bleach is too thick, add ½ measure of the developer.
  • If the bleach is too liquid, add ½ measure of bleach powder.

Blend until there’re no lumps.


Tip 5: Prepare the bleach in a plastic container

before applying it to the hair

You should always use plastic elements. The developer loses its effect in contact with metals. Alternatively, wood absorbs the humidity.

Therefore, a plastic container is ideal and recommended.


You can also buy a coloring kit that contains a graded plastic container, a hair dye brush, and gloves and use them to prepare the bleach.


Tip 6: Add a few drops of coconut oil to the bleach to protect your hair

for everyday use

If you don’t have coconut oil, you can use a moisturizing conditioner or twenty drops of anti-breakage serum.

This way, your hair will be hydrated and protected during the process. It’ll reduce the damage caused by bleaching.


Tip 7: Pay special attention to where you start applying the bleaching mixture according to your goal

lighten to even out all hair color

  • If you want to bleach all of your hair, apply the bleach from roots to ends.
  • If you want to bleach your lengths, don’t apply bleach to the roots.
  • If you want to bleach only the roots, don’t apply bleach to the lengths.
  • If you want to get some highlights, use the hair dye brush from roots to ends.
  • If you only want to bleach the fringe area, gather the rest of your hair in a ponytail.


Tip 8: Cover your hair when you finish applying the bleach

cover hair to generate heat

Covering your hair after applying the bleach will prevent the reaction from cooling and stopping.

Remember that it all depends on the type of bleach powder you use.


White bleach powder works well with strips. In turn, the blue powder works better with foil strips (to do highlights). If you’re bleaching all of your hair, you can use a shower cap.


Tip 9: Leave the bleach on for twenty minutes maximum

for even results

You should check the process every five minutes to see your hair shade.


  • If it reaches the level you’re looking for before twenty minutes, rinse your hair to stop the reaction.
  • If you don’t reach the color you want within twenty minutes, you should still rinse your hair and wait fifteen days for a second bleaching session.

  If you leave the mixture longer, your hair won’t resist the process. It’ll break and burn. 

So, after twenty minutes, rinse the bleach with cold water to stop the chemical reaction. It’ll cool your scalp if you bleached your roots and it’ll close the hair cuticles.


Finally, use shampoo and conditioner to restore moisture to your hair.


Tip 10: Throw away the remaining bleach

I know you care for your finances. But don’t keep the leftover bleach.


The bleach remains active for only twenty minutes.

Therefore, the leftover bleach won’t be useful for a new bleaching session.



Once you finished bleaching your hair and rinsing out the bleach, you can apply a hair dye or toner.

If you follow these tips for preparing, applying, and using the bleach, you won’t have any problems during the process.
