Usually it's just friends and family and it used to happen way more when i was younger... when i was younger i'd be scared for people to touch it because used so much grease lol... i once had a friend run up to me after i had taken my hair out of a bun and it was a huge dry stringy thick mess almost butt length tell me "it looks like your hair stinks" and me roll my eyes and say yeah right you wish.. and she proceeded to grab it all and stick her face in it only to say no it doesn't stink it smells really good like flowers(i was using herbal essence lol) that by far was the weirdest touch i've had... one of the reasons why i recently stopped using gel is because my little brother can't keep his hands out of my hair.. ever time he touches it, it hurts like heck(because it hard and frozen in place)
