"Going gray is caused by a massive build up of hydrogen peroxide due to wear and tear of our hair follicles. The hydrogen peroxide ends up blocking the normal production of melanin, our hair's natural pigment. Melanin is the pigment responsible for hair color, as well as skin color, and eye colour."

"[P]eople's hair goes gray because of massive oxidative stress caused by a build up of hydrogen peroxide in hair follicles. This causes hair to bleach itself from the inside out. The researchers found that this massive build up of hydrogen peroxide can be reversed with a UVB-activated compound called PC-KUS, a modified pseudocatalase. The research team developed this new proprietary treatment." (Read more here...)
So we're self-bleaching? That last sentence is why we're hearing so much about this four years after the initial study. My husband has vitiligo, and apparently this proprietary treatment will be appropriate for him.
I've decided to cultivate my gray hair rather than dying for three reasons: One, I seriously don't have the time or money to dye my hair every six weeks. Two, I don't want to damage my hair more than necessary. And three, I want to have waist length white hair like my former boss, Mrs. Edwards, who looked like an Ice Queen! I realize this might also make the kids on my block think I'm a creepy witch lady, but either way - result!
What are you doing with your gray hair?
