Has anyone tried MONAT products to help thinning hair? in The Chat Board Posted November 5, 2017 I used their hydration system. And totally broke out. My mom just tried their confidence system. Itâ€™s supposed to help regrow thinning hair. Itâ€™s been a couple months and she hasnâ€™t seen results. Donâ€™t know how long itâ€™s supposed to take.
