The participants started to experience hair growth within just two weeks of treatment. After four weeks, hair regeneration was noticed in 17 subjects and in 6 weeks, significant hair growth was evident in 20 people. The study concluded, after examining the results, that the use of onion juice as a homemade natural remedy for people with alopecia areata had a positive effect.
