I also usually go to messy cuts. Sometimes I go to Makas Barber which is closer to me, the guy that runs the place is really good but some of the others can be a bit mixed.
Severall years ago Image Salon [15 Ferme Park Road,N4 4DS, 0207 998 7070] put a leaflet through my letterbox which in a small bottom corner noted "Mens cut and style". I made an appointment with Kuba and have been getting my hair cut by him every month since. He's better than the West End hairressers I used to use. And now that I've reached a certain age, I get Ewa to give me a pedicure every second time I have my hair cut. Good little place with deliious coffee. Ring for an appointment--£22 for the shampoo and cut.
