That sounds like a good idea! If enough folk take part and offer advice. I'm afraid I'm not much use for it though - never really think about which shampoo/conditioner I use (just whatever's in the house at the time).
But why not start a thread and see what other folk know?
Theres another shampoo I'm trying to get called "Herbal Essence Dangerously Pin Straight Shampoo," but the website I'm getting it from keeps sending me the wrong thins (not that I'm complaining, I now have 3 shampoo/conditioner sets I got for free!)
