Define "work".: While there are many claims that nioxin is a hair regrowth product, they do not come from the company that sells it. The nioxin website states "nioxin is not a hair loss product, but a scalp and hair care regimen designed to improve the scalp health environment and improve the appearance of fine and thin-looking hair." in other words, it might make thin hair look thicker. And that's it.
