By the shedding phase, the hair falls out, which eventually completes its own life cycle. This is an endless process, and other active hair strands take their place.

Based on a study, onion is loaded with anti-inflammatory compounds that can actually help in struggling against loss of hair. However, if you suffer from hair loss due to alopecia, most of the hair in the shedding phase is not replaced as quickly or sufficiently with new hair. The results are people who are suffering from thinning of hair, bald spots, and even visible scalps.

The cysteine molecules which provides hair its additional strength connect with each other through strong disulfide bridges which provides hair its additional strength.

The magnesium, calcium, and potassium in onions also improve the circulation of the blood and even reduce inflammation.

While catalase, glutathione peroxidase, and even superoxide dismutase are enzymes that your body produces in order to break down the extra hydrogen peroxide. Onion has the ability to increase the activity of all three in order to battle against hydrogen peroxide damage. As a result, it can provide protection against the graying of the hair due to free radical damage.
