I have said this to John as well. My recommendation would be to be consistent with pictures. For example instead of showing totally different styles showing different densities, or wet vs dry hair, I think its better to use the same example. I know the factories provide those density samples.. I Think placing them on top of ur skin, and showing each one wet and dry should give people a decent idea. Ideally the same type of hair system with the same style/length etc would be perfect. But I doubt that is feasible. I would suggest Using the sample densities on human skin
