20 Vol Developer

20 Vol Developers

20 vol developer, in expert hands, is able to give hair lift without leaving the hair dry and brittle. That makes it a very popular developer strength for use in Aussie salons. Lower level developers such as 3.5 vol or 5 vol are less likely to lift if the hair hasn't already been pre-lightened.

20 vol developer is commonly used with bleach. It can be added to the bleaching agent of choice to then be applied to the hair through foils, or applied directly if doing a scalp bleach. Additionally, it can be used to help activate hair colour.

A small amount can be added to the mixture for optimum results. It's important to check with the products you're using first. A colour mixing guide can usually be found on the brand colour chart.

Choosing Between Peroxide and Developer

Peroxides have a thinner and runnier consistency in comparison with developers. Developers contain peroxide in addition to conditioners and their thicker consistency is considered better for a balayage.

Additionally, developers tend to have better hair care ingredients, that offer conditioning benefits. As a result, the hair is less likely to become damaged. Some developers come with additives to help protect the hair while colouring. They tend to cost more but deliver better results.
