Since DD I have frizzy hair. It reaches down to my bra strap at the back and is layered. It is not dry, my hairdresser is adamant that it is just frizzy. Have tried Liz Earle's hair oil totally unimpressed, loreal Miracle hair oil, nadda, and frizz ease just makes my hair greasy. Will Kerastase give me smooth shiny hair, or is there something else out there that will stop me looking like Dougal from the Magic Roundabout?
