A study had an 87% success rate at reversing hair loss using the method. A landmark study published in The Journal of Dermatology reveals that crude onion juice could be a surprisingly effective natural remedy for patchy alopecia areata. Researchers found that applying the juice twice daily led to significant hair regrowth in nearly 87% of participants within just six to eight weeks. Results were particularly striking among male participants, who saw a 93.7% success rate compared to 71.4% in women. This simple topical treatment significantly outperformed tap water, which served as the control group, marking a potential breakthrough for those seeking accessible, non-pharmaceutical options for hair restoration. The science behind this unconventional method suggests that onion juice acts as a topical irritant. Experts believe this irritation triggers a localized response that diverts the body's autoimmune attack away from hair follicles, effectively allowing them to transition back into a growth phase. However, the study does come with notable caveats, including a small sample size and a lack of professional blinding, which can introduce bias. While the results are promising, users should be cautious as the high sulfur content can cause scalp irritation or itching, and the treatment’s pungent aroma remains a significant practical challenge for daily application. source: Sharquie, K.
