TRESemme Keratin Smooth Heat Protect Spray offers just the protection your hair needs, without taking away its natural feel. 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 Keratin Smooth, as seen backstage at some of this seasons runway shows. This spray with Keratin and Marula oil from Africa, gives you 72 hours of frizz control and 5 smoothing benefits in 1 system, for hair that's silky smooth but still full of natural movement.
