Hair growth grease, a type of topical treatment, refers to a cosmetic product formulated to promote hair growth. A common example is Jamaican black castor oil, derived from the roasted seeds of the Ricinus communis plant.
Hair growth grease has been used for centuries to combat hair loss and improve hair health. Its benefits include nourishing the scalp, moisturizing hair strands, and stimulating hair follicles. A significant historical development was the discovery of minoxidil, an active ingredient found in many commercial hair growth products, which was initially used as a blood pressure medication.
