They didn’t want to do it because of their “safety” rules. You need to do a patch test 48h- 24h before but if you want to have you hair done on Tuesday it has to be exactly on Monday 10 am because they don’t allow it done early. I came twice for a patch test. Both times I was refused because it was “too early” or “too late. In short go here if you have unlimited time during work hours, if you’re ready for inconsistent communication, rude treatment, and not having your hair done in the end.
