I have bought a voucher for hair colouring for long hair, however as soon as I arrive the stylist approach to ask me in a very rude way that she wanted to see the length of my hair, anyway I did show her and also told her that even though my hair length is at my shoulder to avoid all that I have bought a voucher for long hair. She was not satisfied and said that was a mistake with the promotion and that I need it to pay an extra £10 if I wanted the service. In the end I decided to pay because I was already there and have taken some time off to get it done. Terrible experience!!!! False advertisement.
