I hate having my hair touched. I am and have always been a ginger. My whole life strangers would grab my hair and run their hands thru it. "Oh look at your lovely red hair". I bleached it blonde for a few years when I was old enough. Now I keep it cut pretty short, and the only one who can touch it is my daughter.

oops...I think I got triggered. Anyway, you can ask, just make sure you are prepared for a "no".
