Did you also come across people appreciating onion juice for their healthy long hair?. I did, and in fact, many many times. Out of curiosity and to know if something as simple and readily available as onion juice can really do such a wonder, so, I did some digging and what I found actually amazed me, will make you too. I found out that onion juice can effectively cure spot baldness medically termed as alopecia areata.

Onion juice cures spot baldness: Study

A 2002 study conducted by the University of Baghdad and published on the US National Library of Medicine National Institutes of Health revealed how applying onion juice to hair twice a day for 2 months treated spot baldness both in men and women.

Two groups of patients with spot baldness (alopecia areata) were studied over a period of two months.

Group A (onion-juice-treated): The group consisted of 16 males and 7 females with ages ranging from 5-42. The group was advised to apply onion juice to the hair twice a day.

Group B (Control group; tap-water-treated): The group consisted of 8 males and 7 females with ages ranging from 3-35. The group was advised to wash hair twice a day with normal tap water.

Results: The onion juice group started growing terminal coarse hair within just two weeks of the treatment. By the end of the study period, 22 out of 23 patients treated with onion juice regrew hair.

Only 2 out of 15 patients treated with tap water showed some signs of hair regrowth.

Thicken, strength, and elongate hair

Other than bringing back the lost hair in spot baldness, onion juice can do other wonders as well. This includes strengthening, thickening, and preventing hair whitening. The method of growing long healthy hair using onion juice is something people practice for hundreds of years. If there are no researches to back these claims, it’s simply because none were made to verify or otherwise nullify them.
