Girls with thick hair know that it's not easy to keep it sleek - if you're not careful, thick can easily turn into coarse and unruly. Tame the beast with Shu Uemura Art Of Hair Shusu Sleek Smoothing Treatment Mask, specially formulated for coarse, frizzy hair. This powerful product will help reduce frizz, getting rid of that bird's nest effect once and for all!

Exotic black cumin oil is the key ingredient in this product. It contains healthy oils like omega 3, 6 and 9 to smooth and hydrate your hair, giving you a softer, sleeker texture, while nigellone acts as an antioxidant, fighting back against damage. With a light, oriental floral fragrance, this product is free from parabens and silicones, and safe to use on coloured hair.
