Would you tell your hairdresser if she made you look horrible?

I tried all the hairdressers when I moved here and settled on the one nearest to my house. It's five minutes down the hill. I only ever have a dry trim. They listen to me and do what I suggest. If they think I've got it wrong, they say so, and suggest alternatives. I like my hair short. I used to try and grow it long when I was younger, but it never got longer than collar length!
