What is the primary function of bleach in hair lifting, and how does it work?
Bleach is a chemical treatment used to lift hair color by breaking down the pigment molecules. The primary function of bleach is to penetrate the hair shaft and dissolve the melanin, which is the pigment responsible for hair color. This process involves the use of hydrogen peroxide, which is a common ingredient in bleach formulations. Hydrogen peroxide works by releasing oxygen free radicals that break down the melanin molecules, allowing the hair to lift to a lighter shade.
The amount of lift achieved with bleach depends on several factors, including the strength of the bleach, the duration of the application, and the condition of the hair. Generally, bleach can lift hair by 2-4 levels, depending on the starting color and the desired result. However, it’s essential to note that bleach can be damaging to the hair, especially if used excessively or without proper care. To minimize damage, it’s crucial to follow the instructions carefully, perform a strand test before applying bleach to the entire head, and use a conditioning treatment after the bleaching process to restore moisture and shine to the hair.
