This is the problem when you mix business and personal! I fully sympathise with you, but you are paying her for service and if you're not getting it you should be able to go elsewhere. I honestly would find it very difficult if I were in your shoes so I'm no help....maybe you could get in touch in a few days and say it just doesn't look right, could she tidy it up for you.

I used to go to a hairdresser who was a brilliant cutter (ubnlike my previous one at the same shop who retired) but I stoppped going because prices went sky high almost overnight. Now I have someone from a friend's recommendation and friend and I are getting into a similar situation as yourself....B is a lovely girl but not a good cutter
