Beard bleaching agent, also known as sweat hair bleaching agent, is a bleaching cosmetic that acts on fine sweat hair and can be used for bleaching of fine facial hair, small beard, excessive sweat hair, excessive thick eyebrow hair and other hairs. By using the bleaching agent, small beard and body hair can be bleached quickly, and the hair after bleaching is transparent, which immediately eliminates the trouble of small beard and heavy sweat hair. The principle of beard bleach is similar to hair bleaching, which allows the original hair color to gradually fade to blonde to facilitate reagent coloring. It is well known that bleaching and dyeing hair is very harmful to the scalp and hair, and by the same token, beard bleach can also harm the skin. Therefore, it is not recommended that candidates use beard bleach frequently or for a long time, especially for people with sensitive bodies or sensitive skin, because facial skin is fragile, especially sensitive skin, and beard bleach may cause allergic reactions, or burns if used improperly. If you need to use this type of product, it is recommended to perform a skin test before use to avoid adverse reactions. It is important to note that beard bleach does not permanently whiten fine hairs and will gradually fade and require repeated bleaching to maintain its effect.
