What is the function of a hair lightener?

The function of a hair lightener primarily is to remove pigment from hair. This process is achieved through the use of chemicals that break down the melanin, the natural pigment found in the hair, allowing for a lighter color. Hair lighteners can create various shades of blonde and are often used in techniques such as highlights, balayage, or full-head bleaching.

The ability to change the color of the hair by removing pigment makes hair lighteners a popular choice among clients and professionals looking to achieve different looks or to prepare the hair for subsequent coloring processes. Understanding this role is crucial for anyone working in the cosmetology field, as it directly influences the results they can achieve with various hair color services.
