I thought I had asked this question here, but I don't see it.
My hairdresser is actually the owner. I usually tip her, but once in a while, I forget while she's ringing up my card. She waves it away when I ask her to ring it back in, but I make up for it the next time.
I've read that you should never tip the owner, and she's not doing anything fancy or out of the ordinary, so would you tip?
On the same topic, I had to have another girl do my hair when my stylist wasn't available, and I prefer the way she highlighted it. I mean, the other girl rocked my highlights; she threaded them, versus the chunkier way my lady does it, despite my explaining/asking. Is it rude to have another girl do my hair at the same business if my usual stylist is the owner?
