I started going grey in my 30's and before I was 40 I was totally grey. I had to go every 3-4 weeks to have color touched up. We moved from NJ to Florida in 2000 and I didn't know anyone so I decided to get my hair cut really short and just let the color grow out from there. I'm really glad I did. I ended up with a platinum with natural highlights. People ask me all the time where I get my hair colored. That is really funny because I used to beg my mother to let me dye my hair platinum blonde. It is a whole lot healthier that I stopped putting color on it.
