Ideal for fine, fragile and thinning hair, the Nioxin Deep Protect Density Mask nourishes the lengths to promote a fuller appearance while protecting from breakage and excess hair fall. Fortified with Densiprotect™ technology, the lightweight mask deeply conditions and hydrates the strands, encouraging a volumising effect with a thicker-looking finish. Suitable for all hair types, including coloured and curly, apply after shampoo and allow the softening formula to nurture the lengths in a silky-smooth veil, enhancing subsequent manageability and supporting a high-shine result.
