I have very straight, flat hair. More than anything, the flatness annoys me because it means I couldn't do much in the way of styling. It also made my hair look pretty lifeless. When I started using the Herbal Essences Body Envy shampoo (in conduction with the Body Envy conditioner), I immediately noticed a difference. My hair now had volume, a definitive shape! Not only that, but I have never seen my hair so shiny without being oily. I love being able to fluff out my hair, but most of all I love that my hair no longer looks like I iron it every day. I highly recommend this for women (and men!) with flat, lifeless hair. Effectiveness It does indeed give your hair definition and volume! I recommend following it up with the Herbal Essences Body Envy conditioner. This will not only give your hair volume, but it will also give your hair a nice coat of shine. The compliments will just come pouring in! Scent The scent is a little fruity/citrus like, but it's not too overpowering and everyone always compliments me on how great it smells.
