What Is 20 Volume Developer and How Does It Work for Hair Bleaching?

20 volume developer is a hydrogen peroxide solution that contains 6% hydrogen peroxide. It is commonly used in hair bleaching and dyeing processes to lighten hair color by lifting the existing pigment.

According to the American Academy of Dermatology, developers are classified by volume, which indicates the strength of the hydrogen peroxide concentration. This volume affects how much the hair’s natural pigment can be lightened when combined with bleach.

20 volume developer is suitable for lifting hair color up to two levels. It works by opening the hair cuticle layer and allowing the bleach to penetrate the hair shaft. This oxidation process dissolves the melanin, the pigment responsible for hair color.

The National Institutes of Health states that the effects of hair bleaching vary based on hair type and condition. Factors such as porosity and previous chemical treatments can influence the bleaching outcome.

Possible contributing factors for the results include the hair’s natural color, damage level, and the duration of processing time. Over-processing can lead to breakage, while under-processing may not achieve the desired lift.

Statistics show that about 83% of women in the U.S. have colored their hair at least once, with lightening treatments being particularly popular, according to Market Research Future.

Hair bleaching can lead to dryness and possible allergic reactions. Environmentally, the disposal of certain chemicals from hair treatments can contribute to water pollution, negatively affecting aquatic life.

For healthier hair bleaching, the American Pregnancy Association recommends conducting patch tests to prevent reactions and using nourishing products post-treatment to maintain hair health.

Practices to mitigate adverse effects include using lower volumes for sensitive hair types and incorporating deep conditioning treatments before and after the procedure. Proper timing and products can ensure desired results while minimizing damage.
