Sorry, I know, I know, this has been done 1,000,002 times but I can't find a thread on the first page. How much do you tip your hairdresser/beautician? Just totaled up a haircut, eyebrow thread, eyelash tint and perm is £106, so wondered is £120 OK? Too little? I get very shy about tipping so want to have it all sorted before I go. Thanks!
