My mom started dying her brunette hair in the early 70's. When she had chemo 4 years ago, she decided to let it grow back grey. After chemo, she had lasik surgery and I have to tell you, my mother looks fabulous with her beautiful blue eyes and silver hair, especially if she's wearing pink or light blue! :)
Me on the other hand, I've done some highlighting in the past, but have not colored. I've got plenty of grey hair and DH calls me his "silver haired beauty". He also says he gave me all of my grey hairs and he's right!
