i hate this product and same with the Nioxin version as well. both products coat the hair making it look thinner. This product is going in the trash, I am sticking to Bosley shampoo and conditioner, frankly, they work alot better, making my hair volumized! no need for this product.
I paid around $30 for a product that ended up in the trash can (couldn't return it). Didn't give me any volume or thickening effect...all I got was coated sticky unwashed looking hair, no matter how little or little bit more I've used. I bought this because I love the matching shampoo.
