HeatBounce Conditioning Heat Protectant

A conditioning heat protectant formula powered by resilicore™ heat shielding technology to help prevent heat damage up to 450°F from the inside out, condition and detangle hair, and defend against heat, mechanical, and UV environmental damage that can cause color fade, dryness, dullness, and breakage.

This leave-in conditioning heat protectant detangles, softens, and delivers deeper heat protection than ever before*—for 85% less breakage after blow drying.

resilicore™ heat-shielding technology is a breakthrough innovation inspired by resilin—a natural protein that can withstand extreme temperatures.
Unlike traditional heat protectants that only coat the cuticle, the size + molecular makeup of resilicore™ allows it to penetrate deeper than ever before*, into the cortex where heat damage can occur, forming a protective shield that fortifies from within.

  • Conditioning blendconditions, softens, and detangles even damaged hair
  • Created for all hair types + textures
  • Can be used on extensions
  • Protects from heat up to 450°F
  • 85% less breakage after blow drying

Not great for blow drying!!! Grimy & Stiff feeling

Pre-blow dry the product is great. Good detangler, softens my hair. However it’s a blowout product and I greatly dislike how my hair feels after it’s dry. Feels grimy and a heavy film over its. My hair feels stiff and dry and it didn’t help with humidity. If I can return this I will!

Not worth it

Used on fine damaged hair without noticeable results. Not worth the price.
