The only time I've gotten annoyed is when a coworker was using a duster stick (sans duster) to poke at my hair. This particular guy likes to see how far he can get with anything before I react though, which doesn't usually bug me - it's like a competition...but I didn't want frizz.
My boss will pet my hair or grab a handful every now and then, others do it too, but it's never been anything that will mess it up - they've always been gentle. I take it as a compliment. Maybe it doesn't bother me because I've always been a very tactile person. If I see something that has an interesting looking texture, I have to touch it. I don't usually mess with other people's hair without asking, though...not anymore. I used to.
