My hairdresser sold me this product, because I have an annoying chunk of hair that is completely unmanageable! While the rest of may hair will fall straight, sleek and shiny. This piece of hair will look fine in the morning after straightening, but during the course of the morning it will slowly become more and more frizzy and coarse, until it is almost standing at right angles to my head! VO5's So Smooth Smoothing cream works, but I also have to use a thermal protection spray, just in case, as I am so worried about heat damage from my straightener and then I also have to sometimes use serum on top of that and I wanted to use one product which performed all those roles. This blow style lotion made my hair bouncy, soft and shiny... except that one chunk of hair started doing its own thing again, and I had to use the serum several times during the day to keep it in place!!!!
