A lightweight heat protector spray that defends your hair against damage from blow dryers, straighteners, and curling tools. Infused with silk proteins to maintain softness and shine. If you regularly use heat styling tools, your hair faces daily stress and moisture loss. This thermal protector creates a barrier between your hair and high temperatures, helping to prevent breakage, dryness, and loss of shine that comes from repeated heat exposure.

  • Guards hair against heat damage up to 450°F
  • Seals the hair cuticle for a smoother, shinier finish
  • Lightweight formula that won't weigh hair down or leave residue
  • Silk proteins work to nourish and strengthen while styling

How to use: Spray evenly onto damp hair before using any heat styling tools. Work through the hair with your fingers or a comb to ensure full coverage. Allow a moment for the spray to set before applying heat. Use on both mid-lengths and ends for best protection.
