$35 about every 6-7 weeks.
I have a friend do it for £30. I don't mind as all the barber shops here are awful, plus she's professionally trained from a top salon and does the job cheaper than them.
When not shaving his head my husband pays 40$ plus a 5 to 10$ tip. It is a lot but he really adores his hairdresser who he has been going to for close to 20yrs. It makes me laugh because I only pay 30 plus a 5 to 10$ tip for my haircuts.
