CHI Silk Infusion Reconstructing Complex Treatment (59ml) is a nourishing leave-in treatment designed to restore and protect damaged hair. Infused with pure silk proteins, wheat, and soy proteins, this formula helps to repair, strengthen, and hydrate hair, leaving it soft, smooth, and shiny. The treatment works by penetrating the hair shaft to provide deep moisture and enhance elasticity, making it ideal for dry, brittle, or over-processed hair. It also helps to reduce frizz and prevent heat damage, providing a protective barrier for styling. The 59ml size is perfect for regular use to maintain healthy, vibrant hair.
