My real hair color is mousey brown (yuk). I use a non-peroxide color, Clairol Radiance, to richen my hair color. Since I'm 51, I guess it is normal to see more grey hair, and that is what's coming in. But, boo-hoo, prior to last fall, I had very little grey hair. Maybe the damage to my follicles from seb.derm. has "aged" the follicles to produce grey hair (or however the science works)?? If all I can get is grey hair, bring it on!! Grey hair is better than thin hair :hairy: !!!!!
