This luxurious hair mask is expertly formulated to transform dull, colour-treated hair, enhancing its natural radiance and protecting its vibrancy. Infused with Glycolic Acid to laminate the hair fibre for a sleek, polished look and Rosehip Oil to intensify vibrancy, this treatment delivers a softer, smoother feel with a mirror-like, glossy finish. Apply this indulgent mask to clean, damp hair, leaving it to penetrate deeply before rinsing thoroughly to reveal a luminous, healthy-looking glow
