Bleach

This Dalston salon was a trailblazer of the dip-dye trend, as seen on the famous barnets of Lady Gaga and Alexa Chung. Founded by colourist-of-the-moment Alex Brownsell, and her agent and friend Sam Teasdale, Bleach has a client list that reads more like a who's who of London party people, including Pixie Geldof, Daisy Lowe and Alice Dellal, and happily co-habits its Dalston space with Wah Nails – so you can get art on your finger tips as well as your hair. While colouring here is truly expert, don't bother popping in for a set of honey highlights – Bleach specialises in the dramatic: two-tone hair will set you back £80, a full head of highlights £120. While Brownsell, and the Dalston salon, are usually rammed with back-to-back industry appointments, there's a concession in Topshop Oxford Circus.
