Our store's hair turning black treatment utilizes the essence of precious ancient Chinese herbal formulas to help hair naturally regain its blackness and luster through three scientific mechanisms:  [Activating Melanin] Ingredients such as Polygonum multiflorum and black sesame deeply nourish hair follicles, stimulate tyrosinase activity, and promote melanin synthesis.  [Improving Microcirculation] Blood-activating ingredients such as Angelica sinensis and Ganoderma lucidum, combined with scalp acupoint massage, enhance the nutritional supply to hair follicles.  [Delaying Hair Turning White] Antioxidant ingredients such as Platycladus orientalis leaves, Centella asiatica, and Chrysanthemum morifolium neutralize free radicals and extend the melanin cycle of hair. After a 28-day treatment cycle, 86% of customers reported that new hair growth turned noticeably black, and the hair texture became stronger and more lustrous."
