Ok, anyone with red, green, purple, yellow or blue hair. I don’t get it, now having said that my 16 year old daughter wanted to change the undertone of her hair blue. For the first two years I said no. Finally, at a moment of thinking it was her hair, and her soul- I trusted her taste and bought the dye.
To be perfectly honest it looks kind of cool. We get to spend 45 minutes every two weeks, sort of doing girl stuff. And when all is said and done, I am glad that she is happy enough with the way she looks to wear blue hair undertones. A week later she came in my room and had a heart to heart about her problems and decisions. Not sure- but maybe some battles are better to let your children win.
