How Long to Leave Bleach in Hair 20 Vol?

Many people believe that bleaching your hair will automatically damage it, but this isn’t always the case. In fact, bleach can actually be quite beneficial for your hair if used correctly. It can help to strip away unwanted build-up, leaving your hair looking and feeling healthier.

However, it’s important to note that bleaching your hair is a chemical process, and as such, it’s important to be careful when using bleach. One of the most important things to keep in mind is how long to leave bleach in your hair.

If you leave bleach in your hair for too long, it can cause serious damage. Bleaching your hair damages the cuticle, which is the outer layer of your hair. This damage can lead to dryness, brittle hair, and even breakage.

On the other hand, if you don’t leave bleach in your hair long enough, it won’t be effective. Bleaching your hair is a two-step process: first, the bleach must penetrate the cuticle, and then it must react with the pigment in your hair.

If you don’t leave bleach in your hair long enough for it to penetrate the cuticle, it won’t be able to react with the pigment, and as such, your hair won’t lighten.

A 20 vol developer is a hair bleaching product that contains hydrogen peroxide. The concentration of hydrogen peroxide in a 20 vol developer is 6%. This means that it can lighten hair by up to five levels.

A 20 vol developer is a strong bleaching agent and should only be used if you’re looking to make a significant change to your hair color. If you’re just looking to add some highlights or lighten your hair a few shades, then you should use a weaker bleaching agent, such as a 10 vol or 15 vol developer.

What Is the Difference Between 20 Vol and 30 Vol?

The main difference between 20 vol and 30 vol developer is the concentration of hydrogen peroxide. A 20 vol developer contains 6% hydrogen peroxide, while a 30 vol developer contains 9% hydrogen peroxide.
