The latest research by French scientists on why our hiar growing gray as we getting older revealed that hydrogen peroxide may play a key role in the process. If that is the case, the graying process would be more like a “natural bleaching”. 

If one is looking for supporting evidence, he or she does not need to go too far. A Chinese herb named ”He Shou Wu” (polygonum multiflorum), literally meaning “black head” in Chinese, has long been used to prevent premature gray hair.  Laboratory studies by Chinese and Japanese scientists suggest that polygomum multiflorum could increase syntheiss of antioxidant Anthraquinone in cultured hair folics. Anthraquinone is a strong redox  agent. The fact that A derivative of anthraquinone (2-ethylanthraquinone) is used to produce hydrogen peroxide commercially suggests that it could be involved in life cycle of hydrogen peroxide synthesis and eleimation. If that is confirmed, we may find another link of traditional Chinese medicine with modern medicine.
