L’Oréal has just unveiled a new super-gentle, ammonia-free hair color system, called INOA, that produces rich hues, makes strands soft and shiny, and doesn’t have that migraine-inducing dye stench. Only a handful of salons in the U.S. have it so far. Book your appointment now at Jay Michael Salon in Ardmore or Laurentius Salon near the Italian Market, and at Salon Vanity in Washington Square come March.
