Antioxidants are substances that have been linked to many health benefits. A diet rich in antioxidants has been linked to a reduced risk of chronic diseases, such as heart disease and cancer. The benefits also seem to extend to hair loss, which affects two-thirds of men at some point in their lives. Scientists applied the antioxidant resveratrol to areas of recently shaved hair and saw the hair grow back along with strengthening the skin cells that protect the hair. The study was published in the Journal of Clinical, Cosmetic and Investigational Dermatology.
The antioxidant used in the study was resveratrol, a naturally occurring compound found in grapes, berries, and peanuts.
A similar study published in the International Journal of Cosmetic Science examined the possibility of boosting beauty products with antioxidants to prevent hair loss.
They found that people applying the antioxidant shampoo saw a reduction in hair loss.
An added benefit reported was fuller hair and healthier skin.
DO NOT MISS
The science of hair loss is currently incomplete as the role of aging is 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 is lost, usually from the age of 30.
Hair loss has been linked by researchers to loss of self-confidence and low self-esteem, but does not directly produce other health risks.
The risk factors for hair loss are largely genetic, with male pattern baldness being a common inherited trait.
Illness, stress, and hormonal imbalances are other factors that can increase the risk of hair loss.
Sudden, severe hair loss can be a sign of more serious medical problems such as thyroid problems.
Depending on the cause of the hair loss, it can be reversible.
