Hair photobleaching is a process that involves using ultraviolet (UV) light to lighten the color of hair. It can be done naturally by exposure to sunlight or artificially using a chemical solution. The process works by breaking down the melanin pigment in the hair, which is responsible for its color.
Hair photobleaching can be used to achieve a variety of looks, from subtle highlights to dramatic platinum blonde. It is a popular technique for both men and women, and it can be done at home or in a salon. However, it is important to note that hair photobleaching can damage the hair, so it is important to take precautions to protect it.
