What Else You Need to Know
Heat protection from cuticle to the cortex*: resilicore™ heat-shielding technology is a breakthrough innovation inspired by resilin—a natural protein that can withstand extreme temperatures. Unlike traditional heat protectants that stop at hair\'s cuticle, resilicore™\'s size + molecular makeup allows it to penetrate deep into the cortex, forming a protective shield that fortifies from within. This targeted protection delivers extended defense where hair needs it most.

Weightless conditioning: Lightweight cream transforms into a spray + binds to hair to help regulate lasting moisture balance, detangle, smooth for more manageable hair. pH-balanced formula minimizes cuticle swelling for less frizz, and more shine.

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