Defend your hair from structural heat damage, lock in sleekness, and boost natural shine with the iconic formula of the CHI 44 Iron Guard® Thermal Protection Spray, this pro-grade formula works inside-out to seal, protect, and strengthen hair strands before they ever touch hot tools.

Key Features:

• Superior Thermal Protection: Engineered to shield strands against extreme styling heat from flat irons, curling wands, and blow dryers, keeping the internal hair bond secure.

• Enriched with Silk Proteins: Formulated with essential silk elements that penetrate the cuticle to lock in hydration, dramatically improve elasticity, and build a smooth, reflective surface shine.

• Balanced pH ~4.5 Base: Features an acidic chemical structure that instantly closes and tightens open hair cuticles, dramatically cutting down daily styling frizz and static.

• Paraben-Free & Weightless: Delivers a clean, residue-free layer of protection that won't create heavy buildup, feel sticky, or weigh down fine textures.

• TSA-Compliant Travel Size: Packaged in a vibrant red, travel-friendly 2 fl. oz. (59 mL) spray bottle featuring a precise finger pump and clear protective cap, making it perfect for your carry-on luggage.
