I know this is an old post...
If I don't expect it, I react violently to someone touching my hair. I understand - my hair is quirky, with cork screw curls that spring bag to place when a tress is pulled, so people want to touch. But that's ONLY in the case that it's unexpected.
However, if there's one thing I love, it's having my hair played with when I've given permission. Nothing can put me to a near comatose state as quickly as that. With my ethnic background, it was imperative that as a youth my mother kept my hair well done either every day or every other day, so the sensation of her pulling, twisting, using the comb to create a split was all pleasantries to me. And when she washed my hair! Oh boy! I loved the scalp massage! And then my father did something weird - he would use a needle and poke my scalp from time to time, no doubt to playfully torture me. But boy did I love that sensation as well, and surprised him with an, "Again, Poppi!". From time to time, he will still humor me and do that for a minute or so, poking, poking, poking gently with a needle or safety pin.
