First time visit, I was pleased with my hair colour although not so much after I left and realised I still had dye all round my hairline. I also had a cut which was okay.
I felt less appreciated as a customer, being a treatwell customer. The hairdresser reminded me I couldn't ever use this voucher again, a couple of times. They did a nice job with my hair though I had to wait a whole as they flickered between clients. Not worth the money that you pay, but I guess that is London for you.
