What Else You Need to Know: 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 and 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. This formula was created for all hair types and textures and can be used on extensions.
