I pay £19 for a wet cut, but I have short hair and she dries it and puts a bit of gunk on it too, so it is basically a cut and blow dry really! I do go regularly though, depending on how short my hair is at the time - if I have it in a really short style I can't go much over a month between cuts.
I have paid a lot more, but I was lucky to find this hairdresser locally who does a great job and is cheap.
