HASK Biotin Boost

When you wash your hair, shampoo opens the hair's surface structure – the cuticle. That's why it's important to follow up with a conditioner to seal the cuticle back down. That's exactly what HASK Biotin Boost conditioner does. In addition to closing the hair fibers, it nourishes, hydrates, and softens them – everything beautiful, shiny, healthy hair needs. It protects hair from mechanical damage and dryness, smooths the surface, and makes combing and styling easier.
