My hair is a-la-Jenny (my stylist LOL) and she does a great job hiding my greys. Naturally I'm a mousy brown but she makes me a reddish brown. I tried using the boxes (Miss Clairol and L'oreal were my friends) but when my hair turned green, I found Jenny! At 43, I got too many greys to count. Mom was totally white in her thirties and I won't cave.
