Onion Hair Treatment

We all have had nightmares about losing all our hair. Hair loss is very common and may involve bald patches, complete baldness, or gradual thinning. Hair fall or thinning is due to a hereditary condition called androgenetic alopecia. Various causes can trigger alopecia. For instance,  side effects of some medications, hormonal imbalance, stress, local skin disorder and nutritional deficiency are some of the causes. Onion juice is a known remedy for hair health, specifically for hair loss. It has been used for decades for hair problems as a home treatment. Onion juice is said to have other additional hair benefits such as: dandruff, dry or brittle hair, scalp infections like bacterial and fungal infections.  It restores luster and shines to hair.

Onion juice for Hair

Human hair is made of a fibrous protein called keratin which is rich in sulfur and is required for proteins to maintain the shape, strength, and health of the hair. Disulfide bonds stitch these proteins together, giving them strength and rigidity. These bonds are responsible for making the hair healthy. But Too much exposure to sunlight and products such as bleaches, straighteners, and dyes breaks the disulfide bridges, making hair brittle.

Hair loss is very common nowadays in men, termed as ‘Androgenic alopecia’ (male pattern baldness) and women too experience hair loss  (female pattern baldness). It’s all due to Dihydrotestosterone (DHT) imbalance. An increase in Dihydrotestosterone (DHT) levels has been one of the primary contributors for both male pattern baldness and female pattern baldness. All these conditions can be treated with Onion juice.

Onion contains sulfur, flavonoids, vitamins c, antioxidants, and some minerals. Researchers have found that the antibacterial and antifungal properties of onions help to prevent hair fall. The sulfur compounds present in onions are responsible for the smell and flavor of onions.  When you apply onion juice, the disulfide bond makes the hair stronger nourishes your hair follicles, and helps in minimizing the hair thinning and breakage. The sulfur from onions may also help promote collagen production. Collagen, in turn, helps the production of healthy skin cells and hair growth. It’s also believed that onions may boost circulation. Applying onion juice to the hair and scalp could increase blood supply to hair follicles, which in turn improves hair growth.
