So what exactly is keratin? Scientifically, keratin is an intensely strong protein that has been found to be a major component in all skin, hair, nails, and even teeth. Every day, our body sheds millions of these cells due to stress, improper diet, environmental conditions, and lack of care. Keratin has been put into liquid form to replace old cells with new ones, consequently replacing and restoring elasticity and durability to your hair's true and natural condition. When used in our keratin treatment, it seeps into the core of the hair cuticle and is sealed in by heat to replenish those nutrients that we lose daily. The result is softer, shinier, and virtually frizz-free hair.
