I am 80 percent gray and not 40 so color is a must for my. My sister colors my hair for me now and we have fun with it. I am not picky as long as the gray is covered and it is not too outrageous. Last week I cut myself bangs again on a whim and I am happy with them. I have a high forehead with wrinkles creeping in.
I haven't cut my hair in almost a year and recently have started a no shampoo regimen. I have very thick hair and so far so good.
