In order to choose the right volume developer for lightening your hair, you have to learn as much as you can about developers.
They are known as activators because, without them, hair dye would not have an effect. A developer helps the color penetrate the hair shaft and turn permanent.
Hydrogen peroxide lifts the cuticle layer of your hair. Depending on the strength of the activator, the cuticle will lift more or less.
Hair developer levels refer to their oxidizing potential or determine how much hydrogen peroxide they have. Most hair color and bleach formulas use developers at either 10, 20, 30 or 40 volumes.
If you pick 40, know that it causes the most damage to them all. Now, let’s learn a little bit more about developers.

What Should I Do Before Bleaching my Hair?
I already mentioned that both 20 and 30 volume developers work because they penetrate deep into the hair and oxidize its natural pigment.
That is why, once you have bleached your hair, it takes a while to go back to your natural color but keep in mind that bleaching your hair is damaging and not recommended.
If you still want to bleach your hair, apply my tips in order to decrease the damage. First and foremost, if you have already dyed your hair, you should wait at least 3 months before bleaching it.
Also, try to keep away from flat irons and hair dryers. I also recommend using sulfate-free shampoos instead of regulars.
2 weeks before bleaching, I suggest that you do a deeply nourishing treatment at least once per week.
You can use homemade or store-bought masks. Another important advice is that you use coconut oil the night before bleaching. You can buy organic coconut oil.
It is solid and you can melt as much as you need in a double boiler. Spread it out over your hair and wrap it up in a shower cap. Leave it overnight and the next day, without washing your hair, bleach it. If you want to learn how to do it right, follow these steps.
How to Lighten Your Hair Right: 5 Easy Steps
Lightening your hair is not a hard process. But to protect your hair from greater damage, you should do it properly. Please, follow these five easy and simple steps on how to lighten your hair the correct way.
Mix the developer and bleach powder in a small bowl using 2 parts bleach to 1 part developer. Maintain this proportion depending on the quality you need in order to bleach your whole head.
Split your hair into sections for easy application. It is best if you start with the part underneath.
Apply the mixture with a brush. Start at the ends and the length of your hair because roots need less time to lighten. I suggest leaving your roots for the last 10 minutes so that your ends match your roots. After you have covered the underside, it is time to do the same with the upper part.
Cover your hair with a shower cap and leave it for 15 minutes. Check every 3 minutes of how the bleach is working on your hair. Never let the mixture on your hair sit for more than 30 minutes.
Once 30 minutes have passed, rinse your hair well. I recommend using a sulfate-free shampoo. Let your hair dry naturally. If you notice yellow parts, use a purple shampoo to neutralize them.
