Will rogaine (minoxidil) make my hair grow thicker?

Minoxidil Works!: The active hair growth ingredient in FDA-app'd Rogaine=minoxidil. When used properly & consistently, Minoxidil helps weak follicles grow thicker, longer & more pigmented hair. In hereditary hair loss, Minoxidil stimulates & keeps hair follicles in the growing (Anagen) phase. If you're not experiencing hair thinning, results are less dramatic. It takes months to measure results. Seek an ABHRS MD.
