Like a sunscreen creates a barrier between the sunrays and your skin, a thermal protectant spray for your hair forms a barrier between your hair styling tools and your hair. Using a thermal spray before your heat styling tools protects your hair strands from damage by forming a protective layer over your hair cuticles. Some thermal protectants sprays also help to tame frizz and add shine to your hair. The Matrix Style Link Heat Buffer Thermal Styling Spray protects your hair from the heat and offers a light hold for smooth and crunch free hair styles. Spray the fine mist of the thermal protectant on damp or dry hair before going in with your straighteners, curlers, or other thermal styling tools.
