(Hibiscus rosa-sinensis) In Ayurvedic medicine, Hibiscus is used as a powerful herb to stimulate hair growth, even from dormant hair follicles. It can stop hair loss and encourage regrowth. It can also prevent premature graying. Hibiscus is rich in vitamin C and amino acids that boost collagen production. (Collagen is the amino acid chain that gives your hair its strength). Ensuring healthy hair growth while strengthening the hair's roots will keep your hair lustrous and healthy, and discourage split ends. Hibiscus can also help balance the pH level of your scalp.
