Nú Brow is a brow-enhancing serum of proteins and vitamins. It contains Capigen, a hair tonic that slows down excess hair loss and stimulates regeneration and MDI Complex, which inhibits the matrix metalloproteinase enzymes that destroy the skin's collagen network. Unlike other eyebrow re-growth products that take months to work, Nú Brow is clinically proven to stimulate the hair follicle within four to six weeks! The gel reshapes the eyebrow line and protects against induced irritation.
