KERASYLIUM™ is a plant-based alternative to keratin, able to repair damaged hair, and to protect it from daily aggressions. The environment and our lifestyle damage the hair every day, altering its major component keratin that ensures hair’s resistance and elasticity. However, keratin-based ingredients that are usually contained in hair treatments are of animal origin. Kerasylium™ provides a plant-based alternative from upcycled milk thistle seed cake. The keratin-like peptides can penetrate deeply into the fiber. Kerasylium™ has a double action: it repairs damaged hair and protects it from daily stress.
