Help. I have naturally dark raven hair and so it is more obvious when my gray roots begin to come out. They are coming out faster that I can handle. I am 37 and began going gray at 25. Now I have salt and pepper hair which makes me look older so I try to have it colored but the grays are stuborn little suckers. Is there any procedure out there that might reverse this loss of pigment in my hair? I am so tired of the hair coloring, since all it does is color my black hair and leave the grays alone. Oy!
