Bleaching hair, a process of lightening hair color by removing pigments, is commonly practiced in Asia. For example, Japanese women have traditionally bleached their hair to achieve a lighter shade, often associated with beauty and fashion.
In Asia, hair bleaching holds cultural significance and offers aesthetic benefits. In modern times, bleaching has become a popular technique to achieve specific hair colors, ranging from subtle highlights to bold, vibrant shades. Historically, Japanese women used a bleaching agent called "yuhaku" to lighten their hair during the Heian period (794-1185 CE).
