Onion Juice (Allium Cepa L.), A New Topical Treatment For Alopecia Areata

The study investigated the effectiveness of topical crude onion juice as a treatment for patchy alopecia areata compared to tap water. It involved 38 patients divided into two groups: 23 patients treated with onion juice and 15 with tap water. The onion juice group showed significant hair re-growth, with 73.9% of patients experiencing re-growth at 4 weeks and 86.9% at 6 weeks, particularly among males. In contrast, the tap water group showed minimal improvement, with only 13% experiencing re-growth at 8 weeks. The study concluded that crude onion juice was significantly more effective than tap water for treating patchy alopecia areata.
