The Dermatologist told me I could take Rogaine for 4 years and I would keep almost all my hair for the rest of my life. I would even get better results when I use Finasteride with it. I’ve never heard about this 3/4 year cycle and then the hair loss magically stops, any idea what she meant? The appointment was very short, about 5 minutes.
Hair has a 3 year growth cycle. Drugs like finasteride impact both the length of this cycle as well as the quality of miniaturized hairs that are present during the growth cycle. Rogaine does not impact the growth cycle but does stimulate new hair growth in some people. For young men, finasteride is a better treatment for hair loss that minoxidil. It sounds like you did not get all of your questions answered.
