Yes, it’s true the humble everyday vegetable, onion really helps boost hair health. Onion juice has been used in ancient medicine as a natural remedy of thinning, falling and graying of hair.
Latest research into this wonder veggie has thrown multiple possibilities into its importance in hair care. Most of it has to do with its anti bacterial, anti fungal and anti parasitic properties that keep the scalp clean of dandruff and hair roots unclogged. Genetic sensitivity to Dihydrotestosterone (DHT) is a major cause for genetic male pattern baldness. Onions has proved to provide the hair follicles with nourishment that has been blocked by DHT sensitivity or due to lack of nutrients from an unhealthy diet.
Greying and thinning of hair is also caused by oxidative stress through a buildup of hydrogen peroxide and a decrease in the natural antioxidant, catalase. Onion juice, when applied to the scalp increases catalase levels on the skins surface, reducing the buildup of hydrogen peroxide and boosting hair health.
Few research results found that just after four weeks of using onion juice, 74% of individuals with alopecia areata (extreme medical case where the immune system forces hair fall) experienced significant hair regrowth. Within six weeks of using onion juice, 84% of the individuals were reported to have hair regrowth.
This simple household remedy is a boon especially for those undergoing hair loss as a result of hormonal changes or the aging process. While further studies are necessary to reach a full conclusion, this is a great start for the fight against hair loss.
