Bloomsbury has a more limited selection for k18 treatment right now, so it's worth casting the net a little wider. A small handful of 3 salons here publish prices — prices start at £35 and rise to £113, with £43 marking the midpoint. Taylor Taylor London at Liberty and Decadence Hair & Beauty both sit among the more highly-rated options. At £43, the middle of the range here tracks the London average for this treatment closely. Fitzrovia, Soho, and Covent Garden are all within easy reach.
