I`ve been alternating between Morrocanoil and Kerastase for a couple of years now, but recently Morrocanoil stuff has become hard to come by in Japan, so for the last 2 years or so it`s been only Kerastase. For my hair, alternating products is a good thing, because it can get sensitized and the good results tend to disappear after a while. So I decided to give my hair (and wallet) a rest, and went for this 20 bucks mask from Nioxin. I wasn`t expecting miracles or anything, but I am pleasantly surprised. This mask works just as well as Kerastase, it`s about 10-15 bucks cheaper, and more conveniently packaged (squeeze tube) for travel. I am already on my second tube and I would consider repurchasing to alternate with Kerastase in the future. The smell is all right, nothing special, but not over the top or lingering either. It may seem like a small tube, but even for my long hair I don`t need too much product to evenly coat everything. I plan to experience with some stuff from Alterna next, but I have two tubes of Nioxin as a back up in my bathroom closet.
