I would have left a 1 unless I hadn't have gone back the next day to sort. the eyebrow last left loads of strays and my left one thinner than my right. I went back the next day to sort it. they were nice and apologetic about it and luckily I had Marianna who did her best to sort so ask for her if get your brows done! she was great. shame I have wonky eyebrows until they grow back, not what I paid for.
