Our Polygonum polygonum White Turn Black shampoo soap contains sodium palmitate and glycerin. It can deeply moisturize and nourish the scalp, balance the oily scalp, strengthen the hair roots, and help solve problems such as scalp itching. The way to use it is very simple: first wet your hair with warm water, then lather it with a foam net and a shampoo stick, massage your scalp and hair for 2-3 minutes, and finally rinse your hair with water to remove the foam. After use, it stimulates blood circulation, nourishes hair, and supports stable nutrient delivery throughout the scalp, promotes hair follicle growth, and improves hair quality.
