This Tresemme Keratin Smooth Deep Smoothing Mask is a salon-inspired treatment designed to transform frizzy, hard-to-manage hair into sleek, manageable strands. Formulated with keratin and marula oil, this mask works to deeply penetrate the hair shaft, smoothing the cuticle from root to tip. The rich, creamy formula helps to control frizz for up to 72 hours while nourishing and softening even the most unruly hair. Ideal for those with thick, curly, or wavy hair textures, this treatment tames flyaways and creates a glossy, mirror-like finish. For best results, use this mask weekly to maintain a long-lasting, smooth appearance without weighing hair down.
