Over quickly and as pain free as a Brazilian wax can be. Would be good if the venue accepted card payments for ease but in future will remember to bring cash.
Be very strict with your hairdresser if you go here. I asked mine not to do several things, but ultimately ended up trusting what I thought would be her professional better judgement. I went in for a trim, but ended up with a too-short, lopsided, straggly haircut I hate and a knock to my confidence.
