ive found this very interesting as I am a hairdresser!! Personally, I would NEVER expect a tip off anyone, but when clients do tip, to me, it is a confidence boost as you feel you have done something right and made them happy. If someone doesnt tip, my paranoia tells me they weren\'t happy with their hair. And I only ever hang around at the till, as we are trained to open and close the visit, by greeting at the door and leaving at the door!
Also, hairdressers, or the majoirty are NOT on a good wage, but thats no need for you to tip i just wanted to point that out! I am a senior hairdresser and wages are poor in a busy city salon.
To me who I tip throughout the year is a personal thing, I will tiip my beautician when she does a lovely job, my waiter/ress, when Im pleased with my service and anyone else who i feel has gone out of their way to be nice to me......
