I booked for medium hair and paid online, however when I got there and blowdry was nearly finished the lady at reception said oh its long hair and you need to pay extra. Online the difference was £2 but in the salon they charged £7.50. They should have told me before the treatment as I could have declined. I have had very long hair and got it cut to just below shoulder length so for me that's medium. However the lady doing the blow dry was lovely and did a great job.
