I have got one client that is just a nightmare all the time..
Today she asked me what colour I used on her hair before so I told her and she went out and got this colour and then texted me saying it was really dark brown[ it was a 7/0} hardly not dark brown .. Anyway I give her some advise what to do and she wants me to go and correct it but I just know she will not be happy what ever I do with it then it ends up costing me in colour.. I need to get rid of her how do I say I don't want to do her hair no more nicely p.s this isn't the first time she has done sometime like this and I felt sorry for her so I go and correct her mess for free I feel sorry for her because she has no money
