Does EXACTLY what it says!
I’ve been using this for a few years and now I wouldn’t know what to do without it. Foil really does control static and frizz. In the winter it’s great because it’s helpful when wearing sweaters and layers of warm clothing that create major static. In the summer it’s extra protection against the humidity that frizzes my hair out of control. I love the way it smells and that there’s absolutely no residue or stickiness.
