How to mix bleach powder and developer

If you want to mix bleach powder and developer on your own, you should follow the steps below to avoid making mistakes. If you are not sure, you can always go to the hairdressers and not worry about it.

1. Mix one part bleach and two parts developer, whether it is 40 or 10. This is the perfect dose that you should stick to.
2. Mix it in a metallic bowl until you get a smooth, creamy texture
3. Apply the paste onto your dry hair that hasn’t been washed before
4. Apply it first to your roots or the parts that have faded the most because they will need more time.
5. Wait and then rinse your hair and wash it as usual.

The vol of the developer will depend on how much you need to lighten your hair; if you want to lift it by 1 or 2 levels, then use 1-20 vol. 

If you want a lighter color, 3-4 levels or more, then you will need 30-40 vol.

What happens if you put too much developer in bleach?

If you put too much developer, then your paste will be more runny and wet. This is not a good texture because you won’t be able to apply it properly, or you may not do it equally on all parts of your hair.

We don’t recommend working with this paste because you won’t be satisfied with the color, and you will need to color your hair again soon. 

Our advice is to make a completely new paste with the right proportions or add more bleach to make a better paste.

The developer, which is basically hydrogen peroxide in a tube, activates the hair color and bleach. Many women think that their hair will become lighter if you add more developed, but it does not work like that.

If you want lighter hair, you should change the vol of your developer, not add more.

How long should I leave bleach in my hair?

It all depends on your natural hair color and what color you want to achieve. If you use bleach at home, you shouldn’t go over 45 minutes.

Going over 45 minutes won’t make your hair lighter; it will only damage and dry it.

Usually, women keep the bleach on their hair for 15-30 minutes and check the color in the meantime. 

For example, if you have light brown hair, you should keep the bleach for 15 minutes and then remove it. That is just enough time to get a lighter tone that will look good on you.

On the other hand, you should wait at least 30 minutes before rinsing your hair if you have dark brown hair.

If you have very dark hair, almost black, then we recommend not bleaching it by yourself. Dark hair is really hard to bleach, and only a professional and several appointments can get a good result.

Should I bleach my roots first or last?

The best option is to apply bleach a couple of inches from the scalp and towards the middle of your hair. Finish with the ends of your hair and then go back to the root.

In this way, your roots won’t end up being dry and brittle because they lift quicker than other parts of your hair.

The bleach shouldn’t be on your roots for longer than 45 minutes because it will start cooking your strands, and you will end up with dry and damaged hair.

This works for almost every hair type, but there is one exception, and you can read about it below.

What if I have dark roots and lighter hair?

If this is the case with your hair, you should do the complete opposite. It would be best if you first bleached your roots and then the rest of your hair.

Darker roots need more time to go lighter. You should put the bleach on your roots and then wait for 15-30 minutes (depending on the color of the rest of your hair) and then apply it to the rest of your hair.

In that way, your hair will look more toned while having a fresh and vibrant color.

If you are not sure whether you have very dark roots or not, you should talk to your hairstylist about the proper bleaching for your hair.

Do you have to wrap your hair in foil when bleaching?

No, you don’t have to use foil every time you bleach your hair. It all depends on how many different colors you want to have and if your hair is damaged or not.

What is the purpose of the foil when bleaching?

The purpose of the foil is to maintain the temperature. If the hairstylist didn’t use foil, the bleaching time would take much longer because the chemical reaction would lose heat.

If you want your hair to look 1-3 tones lighter, then you don’t need foils. If you have dark hair, then you will need foils.

Also, you shouldn’t use foils if you have extremely damaged hair because you will damage it even more. 

Our advice for damaged hair is to skip bleaching and wait for it to recover properly before doing any hair technique. If you insist on bleaching it, you can do it without foil.

Conclusion- How to mix bleach powder and developer

You should always use a proportion of one part bleach and two parts developer. It doesn’t depend on the vol of your developer, so don’t focus on that.

Also, if you use more of the developer, you will end up with a runny paste, and you won’t be able to use it. 

An important thing to keep in mind is that the amount of the developer you use will not affect your hair color. If you want a lighter tone, then you should change the vol of the developer.

Also, the foils won’t affect your hair color; you can use them and skip them depending on your natural hair. If you are going for 1-2 tones lighter, then there is no need to use it.

Also, you should skip foils and bleaching if you have significantly damaged and dry hair because you won’t be able to recover it easily after it.
