How To Use Onion Juice For Graying Of Hair

Research studies say that gray hair is due to a massive buildup of hydrogen peroxide in hair follicles. This is accumulated due to wear and tear. The hair cells produce a little of hydrogen peroxide because this is a by-product of respiration.

As you grow old, the amount of hydrogen peroxide production by the hair cells increases. So your hair starts to turn gray and then white. To make it simpler, you start to bleach your hair from within.

Naturally catalase is an enzyme produced by our body to remove hydrogen peroxide. When the level of catalase is low, and the level of hydrogen peroxide is high.It affects the production of Tyrosinase another enzyme which produces melanin in hair follicles.

Ultimately everything bubbles up to the buildup of hydrogen peroxide in our hair follicles.

Onion juice has been used for centuries for treating gray hair. It is rich in the enzyme Catalase. As we saw earlier gray hair is caused due to the reduced amount of Catalase. Studies say that Catalase neutralizes hydrogen peroxide and reverses gray hair. The buildup of hydrogen peroxide in hair follicles results in graying and thinning of hair.
