Cause of Grey Hair
Graying of the hair is a result of increased levels of hydrogen peroxide, which can bleach the hair from the inside out. Hair cells in people of all ages produce some hydrogen peroxide. But in young people, its effect is low as it’s quickly broken down into its harmless elements of hydrogen and oxygen. With advancing age, hydrogen peroxide is broken down less and builds up in larger amounts in the hair follicle and ultimately inhibits the synthesis of the color pigment melanin. Increasing hydrogen peroxide causes premature hair whitening.
