Study participants were divided into two groups. In the first case, onion juice had to be applied to the scalp, and in the second, only tap water. The procedure was the same for everyone: two applications per day for two months. In just 6 weeks, hair growth has been recorded in 86.9% people who ate onions. On the other hand, in the control group, where tap water was used, more hair grew only on 13% participants. And this was not at week 6, but when a full two months had passed.
