Let the heat-deflecting ingredients in this GHD Thermal Protector form a protective coating around the strands of your normal to fine hair. This lightweight spray from GHD is specially formulated to protect normal to fine hair from heat styling damage. The heat-deflecting ingredients form a protective coating on each strand of hair to provide a barrier from high temperatures of flat irons, curling irons, hot rollers and hair dryers. Added Wheat Amino Acids and Panthenol repair damaged hair and add strength, while the natural Sunflower Seed Extract provides UVA protection to keep out the damaging rays of the sun. If you are following GHD's 4-step thermodynamics™ system, this is step 2 – protect.
