When you wash your hair, shampoo opens the surface structure of the hair – the cuticle. This is why it is important to apply hair care after washing to reseal the cuticle. This is exactly what the KERASILK Essentials Color Protecting Conditioner will do. In addition to sealing the hair fibers, it provides them with nourishment, hydration, and softness, which beautiful, shiny, and healthy hair cannot do without. It protects them from mechanical damage and dryness, and also smooths their surface, helping to soften them and making combing and further treatments easier.
