what is the k18peptide™?
K18PEPTIDE™ is a biotech-developed peptide that mimics hair’s structure to reverse damage by reconnecting polypeptide chains and disulfide bonds broken during damage from bleach + color, chemical services, and heat*
*Disclaimers
why do I need to skip conditioner before using the K18 mask?
Conditioner leaves a film that blocks K18PEPTIDE™ from penetrating effectively. Once the 4-minute wait time is up, feel free to use a conditioner, a leave-in, or any type of product.
is HeatBounce activated by heat?
No, HeatBounce does not need to be activated to protect from heat.
Do I have to wait to use heat after applying HeatBounce?
No, you can blow dry or use hot tools immediately after applying HeatBounce.
how is HeatBounce different from traditional heat protectants?
HeatBounce is powered by resilicore™ heat-shielding technology, an innovation inspired by resilin—a natural protein that can withstand extreme temperatures. Unlike traditional heat protectants that only coat the outside cuticle layer of hair, 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.
