May 2026 in “International Journal of Drug Delivery Technology” The review explores the use of herbal drugs, specifically Hibiscus rosa-sinensis, Allium cepa L (onion), and Aloe vera, for promoting hair growth, particularly in cases of androgenic alopecia. These herbs are noted for their ability to block dihydrotestosterone (DHT), a key factor in hair loss, and enhance the anagen phase of the hair cycle. Hibiscus rosa-sinensis has antioxidant properties that protect hair follicles, onion provides sulfur and antibacterial benefits for scalp health, and aloe vera contains vitamins and compounds that repair hair strands. The review suggests these herbal treatments as promising alternatives to conventional medications like Minoxidil and Finasteride, which have limitations and potential side effects. Additionally, the psychological impact of hair loss and the importance of addressing stress and hormonal imbalances are emphasized.
