What is the difference between 20,30,40 volume developers?
The most used formula or the ideal developer that one should consider while bleaching is 20 volume one as it has 6% peroxide.
2.Oh!’s Hair Lightening Kit comes with a 20 volume developer which has a nice fruity fragrance which leaves the hair feeling soft, shiny and nourished.
30 volume developer, also called as the developer with 9% peroxide, is frequently used with lighteners and will raise the hair up to a higher level, but causes a little more damage than 20 volume developer.
Remember that 40 volume developers used with a lightener can be harmful, if used improperly.
