So I have been to this particular hairdressing salon, 4 times before, (I go every 3 months for a dry cut, and 'Julie' usually cuts my hair.) My old hairdresser retired so I started going to this new one about a year and a quarter ago...
This time I had Lisa. (Julie had rang in sick.) For context, my hair is about 6" below my shoulders, and wavy/curly. It's thick and blonde and I love my hair.
I got into the hairdresser chair to sit down for my cut, and Lisa got the hair straighteners out, then spent about 15 minutes straightening my hair within an inch of its life! Several times I kept smelling burning hair, when she kept them on for too long!!! I kept saying 'my hair is burning, you need to stop.' She carried on, and didn't remove the straighteners for another 10 seconds, and kept chatting shit to her colleague who was a few feet away from her. She barely made eye contact with me, despite me trying to chat - several times!
Then - when it was all straight - she said 'that's much better now it's straight.' I said 'what? Why is it better?' She said 'it looks much better on you than the curly hair.' I said 'but that's my natural hair, it's curly and wavy.' She said 'yeah but it looks better straight.' 
It was 100% flat and straight because she's fucking fried it with the hair straighteners!
She then started chatting shit to her mate again, and proceeded to cut about half an inch off my hair, and a quarter inch off my fringe. No layering or feathering or any attempt to style it. She spent 5 minutes cutting it... And as I say, she cut it very little! Then she said 'all done' and walked to the till... (I could have done that at home, cut that tiny bit off! In about 2 minutes!)
And I don't believe she straightened my hair to make it easier to cut because it's wavy/curly, as every single hairdresser I have ever had, just sprays it with some water, and combs it through, to make it a easier to cut it properly. The silly mare didn't even cut it properly! And she charged me £45 for it. A shitty, non-cut, and half my hair fried!!!
AIBU to never go there again, and should I make a complaint? About the poor cut, her frying my hair, and her basically telling me that my wavy/curly hair is shit?! 2 pics included are 1) what my hair is like, and 2) how she MADE it look!
