Onion 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.
Sulphur ( also called the “beauty mineral”) which is present in every cell of the human body especially the skin, nails and hair, is another important nutrient in onions that decreases inflammation, reinvigorates and regenerates hair follicles growth.
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.
