Hair loss is very common and may involve bald patches, complete baldness or gradual thinning.According to the American Academy of Dermatology, about 80 million men and women in the United States have some degree of hair loss.
The most common cause of hair thinning or loss is a hereditary condition called androgenic Propecia. It can also happen as a side effect of some medications or because of hormonal changes.
One home remedy many people may not have heard of is onion juice.
The use of onion juice for hair regrowth has not been extensively researched.
One small study published in the Journal of Dermatology indicated that applying onion juice to the scalp might help hair regrow in some people.
The study involved participants who had alopecia areata, which is a non-scarring, patchy form of hair loss.
Researchers found that hair growth started after 2 weeks of using onion juice, which was applied to the scalp twice daily.
