This is a great thread that will need to be stickied!
And I'm always trying to get stylists to cut my right side a tad shorter, since it's the straighter side. I have to insist that I don't straighten, and that I don't care if it's even when wet, just how it looks when dry.
I told the last stylist that if she didn't, I'd just go home a snip it myself.
She did it.
