For hair that has become dry, dull, with a mind of its own, it may be time for the HeatSmart Serum Line. The inspiration for this product grouping naturally progressed from HeatSmart Serum (HSS), the award winning Dry Oil Hair Treatment that instantly controls frizz and produces a healthy shine with touchable softness. In its original form HSS is Pure HeatSmart Complex with the added benefits of 3 certified organic essential oils – Argan, Acaí, and Flaxseed. These same hydrating and shine properties can be found in HSS Shampoo, HSS Condition, and HSS Aerosol Spray. And, above all, the heat protection you come to expect from Thermafuse.
