Our new FHI Heat Hot Sauce is the latest achievement in FHI, Inc.'s dedication to developing the most innovative and highest quality professional hair products on the market. Most finishing hair products are silicone-based, which means they simply coat the outside of the hair to leave it feeling smoother. This is a temprary effect and will allow unwatned product residue to build up on the hair. FHI Heat Hot Sauce is moisture-based - when used in conjunction with FHI Heat irons it will actually penetrate into the core of the hiar to reconstruct and deeply condition the hair from the inside out!. FHI Heat Hot Sauce has heat-atived jojoba crystals that dissolve and deeply penetrate into the hair, thus dramatically improving the quality, condition and texture of the hair. This is not a temporary effect - with regular use of FHI Heat Hot Sauce, dry hair will be moisturized and damaged hair will be restored!
