I'm chiming in with a vote that color is for fun!. I've been having weird stuff done to my hair ever since I started bartering personal training for hair styling and color. My client/stylist is awesome when it comes to both. I just wish I had better hair (mine's pretty thin and fine). I've had it extremely short for the last eight years or so because of all the sweating I do when teaching spinning classes, personal training or riding. I've also had my hair with varying shades of purple, fushia, dark brown w/deep maroon highlights, and currently, bright wide blond highlights, with my natural darker brown underneath and a color called "chili" as the third color.
The other day, as I was leaving the gym after teaching a cycle class a woman passed me and said, "I love your hair. I just wish I was that bold!"
Believe me, if I wasn't bartering for this...I doubt I would put this much money into my hair. But...I'm having fun with it. (by the way, I know I have grey in the front. I don't think there's any in the back cause that's pretty short and is my natural hair...but I'm currently growing out my hair somewhat....going from a short cut to an asymetrical kind of bob thing. So, if I have more grey back there, I'll soon know.
Vertically challenged, but expanding my horizons.
