This is a more expensive line of products, costing about $30 for the bottle of shampoo. I was skeptical, but do find that investing in good shampoo/conditioner sets can mean using less product and having better results. I was not disappointed! The reNeu shampoo smells incredibly minty, and feels as though it's stimulating your scalp. My hairdresser explained that I should only condition the ends of my hair after using this shampoo, because it works so well and is so nourishing. I highly recommend it - very lightweight, leaving my hair very silky and shiny and lightweight as well. Smells amazing and I only need a small amount, maybe the size of two peas, for my long hair!
