The Future of Heat Protection

Description

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

*k18proeducation.com/pages/disclaimers

Apply throughout sectioned hair, brushing through to help with even distribution. Use on towel-dried hair before blow drying and on dry hair before hot tools.

resilicore™ heat-shielding technology is inspired by proteins in nature 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 hair's inner cortex where heat damage can occur, forming a protective shield that fortifies from within.

Conditioning blend conditions, softens, and detangles even damaged hair

Created for all hair types + textures. Can be used on extensions.
