In life, sometimes you've got to take the rough with the smooth. But with hair, you really shouldn't have to. Getting a smooth, frizz-controlled style shouldn't mean settling for limp locks or poker straight hair that barely moves. Well, say hello to the new look of smooth, as seen backstage at some of this season's runway shows. TRESemme Keratin Smooth, with Keratin and Marula oil from Africa, gives you 5 smoothing benefits in 1 system, for hair that's silky smooth but still full of natural movement. The system fights frizz, detangles knots, boosts shine, adds softness and tames flyaway. Once or twice a week, switch out your regular conditioner for TRESemme Keratin Smooth Deep Smoothing Mask. This intensive hair mask, with Keratin and Marula Oil, treats every strand and will smooth and nourish dry, frizzy hair, without weighing it down.
