Salon A did good job of cut, bad job of colour.
Salon B did good job of colour, bad job of cut.
I'm inclined to think my hair, my money. But to go to A for cut and B for colour is a bit uncomfortable to think about. It would also cost more but that is secondary to being happy with my hair.
I guess I could explain what it was about the cut that I didn't like. But I don't have the easiest hair (LOTS of it, wavy (neither curly, nor straight), very strong with a mind of its own. Hmmm, bit like me actually)... hence having someone cut it well is rather important.
