Barb Thompson has been cutting, coloring, and styling hair professionally for over twenty years — three of them assisting one of Hollywood's most in-demand celebrity stylists before stepping out on her own. She splits her time between salons in Northern California and Silver Lake, Los Angeles, where she cuts, colors, and styles for a regular client base alongside editorial and celebrity bookings. She is a global cutting educator for R+Co, which means she trains other stylists in technique and philosophy.
