What Is Hair Bleach?

This post was written with Consensus AI Academic Search Engine – please read our Disclaimer at the end of this article. Hair bleach is a chemical treatment used to lighten the color of hair by removing its natural pigments. This process involves the use of various chemical agents that work together to achieve the desired lightening effect.

Composition of Hair Bleach

Hair bleach typically consists of a combination of ingredients that work synergistically to decolorize hair. A common formulation includes a water-soluble peroxygen bleach and an organic peroxyacid bleach precursor. These components are often combined with a bleaching aid to enhance the efficacy of the product while minimizing hair damage, especially at lower pH levels2. Another formulation involves a creamy suspension mixed with an oxidizer just before use. This mixture may contain inorganic peracid salts, alkali-reactive salts, thickeners like cellulose or polysaccharides, oils or waxes, and other additives to improve application and storage stability1.

Mechanism of Action

The primary mechanism of hair bleaching involves the oxidation of melanin, the natural pigment in hair, using hydrogen peroxide. This oxidation process breaks down the pigment, resulting in lighter hair color. The degree of lightening can vary depending on the concentration of the bleaching agents and the duration of the treatment3.

Effects on Hair

Repeated bleaching treatments can lead to significant changes in the hair’s physical properties. As the number of treatments increases, the hair’s surface becomes rougher, and its luster diminishes. The protective layers of the hair are eroded, leading to a decrease in breaking strength and an increase in elongation. These changes are due to the oxidation reaching deeper into the hair structure, causing damage to the hair’s integrity3.

Conclusion

Hair bleach is a powerful chemical treatment used to achieve lighter hair colors by oxidizing natural pigments. While effective, it can cause damage to the hair’s structure, especially with repeated use. Understanding the composition and effects of hair bleach can help in choosing the right product and minimizing potential damage.
