I started washing my own hair after years of going to the salon and after a few months of using this last summer, my hair felt so thick and healthy. I had been using Mane and Tail, which left my hair dry and almost crunchy (if that makes sense). I haven't used this in a while because I got lazy and I've noticed my hair getting dry and thin again from salon visits. I'll definitely pick up on using the Hask shampoo and conditioner again to rebuild my hair's health. I also use the conditioner for co-washing and my hair is so soft and tangle free afterwards. It smells really good as well. I have yet to run out after a year of usage and my hair is pretty thick. A little bit goes a long way.
