GIOVANNI Styling Glue Custom Hair Modeler puts you in charge of your own customized style, so spike your tips, slick your slides, and pull a pompadour. Look in the Ingredients section to find a listing of *USDA certified organic ingredients. GIOVANNI was the first full-range, salon-inspired hair-care brand in natural product stores, and today is the #1 selling Hair Care line in the United States Natural Products Industry. But before there was a brand, there was a pioneer. Arthur Guidotti had a vision and a love for all things hair. He began developing his passion as a hairstylist in Hollywood and Beverly Hills. He worked for a time with hairstylist icon Gene Shacove and was good friends with “the father of hair color,” Al Lapin.
