John Masters Organics

A visit to this environmentally friendly salon—powered by wind energy—is akin to entering an intoxicating botanical garden: The floral scents that waft in the air during the organic scalp treatment will send you into relaxed oblivion, and ammonia-free, herbal-based color treatments will appeal to your inner purist. The Soho spot boasts all-natural shampoos and conditioners (blended from plant extracts and essential oils) and avoids toxic chemicals, like ammonia and sulfates (staples in most dye treatments).
