I'm 76 and have almost no grey hair. Several university studies suggested that catalase enzyme prevents hydrogen peroxide from bleaching the hair at the follicles. The more glutathione being available keeps catalase levels high. If this is all true, perhaps my love of glutathione producing foods like collard greens may hold the key for my lack of grey. I've always been a supplement taker, so NAC supplementation may be an advantage for more glutathione and less grey hair. Have you seen the study on why hair turns grey by the university (I can't remember where, but it can be googled)? I read this years ago.

Excerpt:

A high concentration of H2O2 accumulates in graying hair follicles, as described in published reports [5], [6], which might be explained in part by the intrinsic deficiency of catalase in gray hair since catalase is an important antioxidant enzyme that catalyzes the conversion of H2O2 to water and molecular oxygen [6].
