I'd been coloring my hair since I was 12 yo as my mother was a hairdresser it was easy for me to get what I needed back then. I continued to color my hair till just about the time I would retire at the ripe old age of 57 plus I had a job related injury and they wouldn't give me a desk job to recover so decided to reitre as I had 26.5 yrs in anyway.
Anyway, I was worried how the roots would show up as my hair grew out with the combination of auburn, grey and mousy brown and went to my hairdresser to ask about frosting it. She suggested low lighting it instead when it basically the opposite of frosting. So she added a much nicer brown tint to my hair and I liked it. No one noticed I was no longer dying my hair auburn and now after all these years my grey is coming in as streaks so it almost looks like I frosted it. I worked hard for my grey hairs..............as I keep telling folks....:-)
