Our black hair soap contains sodium palmitate and glycerol. It can strengthen hair roots and follicles, making hair healthier, helping to restore and prevent hair pigmentation, and promoting natural recovery of hair color. It's easy to use: first wet your hair or beard with warm water, rub soap on your palm to produce foam. After that, use foam to massage and wash your hair or beard, and finally use water to rinse foam to make your hair look black and shiny.
