#1: Styling nightmares -- what's yours?
I was looking at the Denman brush and thought about how my sister would pull a brush from root to end in one stroke and yank without stopping at a tangle. She would then braid my hair too tight or put a too tight ponytail in my hair. I'd run screaming as a child when I saw any brush!! I still flinch when hairdressers reach for their brushes.
