Results may vary with every woman being unique, but as an ingredient, minoxidil has been clinically proven to show hair regrowth in just 3-6 months. Minoxidil starts working as soon as you start taking it even if you don’t see visible results right away. Consistency is the key to seeing results, so stick with it and take it as prescribed by your provider. Take pictures and check your hairline every few months to track hair regrowth progress.
