What Is Hair Bleaching and How Does It Work?

Hair bleaching is a chemical process that lightens hair color by removing pigments. It typically involves applying a mixture of hydrogen peroxide and ammonia to achieve a lighter shade than the natural color.

The American Academy of Dermatology describes hair bleaching as a process that alters the hair’s structure to lighten its shade. Hydrogen peroxide acts as the primary bleaching agent, while ammonia helps open the hair cuticles for better product penetration.

Hair bleaching works by breaking down the natural melanin in hair. The process can vary in strength and duration, influencing the final shade. Bleaching can also lead to hair damage if not done correctly, affecting hair’s texture and shine.

The International Journal of Trichology reports that hair bleaching is a widely used cosmetic practice. It is often performed in salons or at home and has grown popular among various demographics, reflecting broader beauty trends.

Contributing factors to hair bleaching include fashion, personal expression, and cultural influences. Many individuals bleach their hair to achieve desired styles or to cover gray hair.

According to a survey by Statista in 2020, about 35% of women aged 18-29 in the U.S. reported having bleached hair at least once. Hair bleaching is projected to increase as trends evolve.

Bleaching can have significant impacts on hair health, often leading to dryness and breakage. Environmental consequences may arise from improper disposal of bleach products.

In health contexts, over-bleaching can lead to scalp irritation. On a societal level, the trend can influence beauty standards and personal identity.

For safer hair bleaching, the American Academy of Dermatology recommends consulting professionals and conducting patch tests to avoid allergic reactions.

Recommended practices include using lower concentrations of bleach and following post-bleaching care routines to maintain hair health.
