Bad hair bleach is a chemical substance or product that causes hair to lighten in color but damages the hair structure, leading to breakage, dryness, and split ends. An example of bad hair bleach is a bleach that contains harsh chemicals such as ammonia or peroxide.
Hair bleaching is a common practice for achieving lighter hair colors, but it can have adverse effects if the bleach used is of poor quality or not applied properly. Bad hair bleach can strip the hair of its natural oils and proteins, making it weak and prone to damage. Historically, hair bleaching has been used for centuries, with ancient Egyptians using henna and lemon juice as natural bleaching agents.
