Antioxidants are substances that have been linked to a host of health benefits. A diet high in antioxidants has been associated with a reduced risk of chronic diseases, such as heart disease and cancer. The benefits also appear to extend to hair loss, which affects two thirds of men at some point in their life. Scientists applied the antioxidant resveratrol to recently shaved patches of hair and saw the hair grow back alongside a reinforcement of the skin cells that protect the hair. The study was published in the Journal of Clinical, Cosmetic and Investigational Dermatology.

Research has previously linked oxidative damage to hair loss alongside the role of regulatory cells called dermal papilla cells.

The researchers found that these papilla cells, which produce chemicals promoting hair growth, grew in number after application of the antioxidants.

There was also an elongation of the hair and an increase in the number of hair follicles over the course of the study.

The research was carried out by multiple genetics and dermatology labs in China.

The antioxidant used in the study was resveratrol, anti leprosy dapsone a naturally occurring compound found in grapes, berries and peanuts.

A similar study in the International Journal of Cosmetic Science looked at the possibility of reinforcing beauty products with antioxidants to prevent hair loss.

They found that people applying the antioxidant shampoo saw a reduction in hair loss.

An additional reported benefit was fuller hair and healthier skin.

The science of hair loss is currently incomplete, with the role of aging not yet understood.

Of the 100,000 hairs you are born with about 100 are lost daily and these are replaced at an equal rate when you are young.

Over time your hair is replaced more slowly than it lost, generally beginning at age 30.

Hair loss has been linked by researchers to loss of self confidence and low self-esteem, but does not directly produce any other health risks.

Antioxidants are a class of compounds that halt harmful chain reactions in the body.

Your cells naturally produce harmful molecules that cause cumulative damage to the cells and to the DNA.

They can be found in many plant-based foods, as well as several vitamins such as E and C that function as antioxidants.

Antioxidants are sometimes added to food to preserve it for longer periods of time.

The risk factors for hair loss are broadly genetic, with male pattern baldness being a common heritable trait.

Other things that may increase your risk of hair loss are illness, stress and hormonal imbalances.

Sudden and severe hair loss can be indicative of more serious medical problems such as thyroid disorders.

Depending on the cause of hair loss it may be reversible.
