My Results from Rogaine are Leveling Off After 3 Years

I’m 61 years old and have been using Rogaine for about 3 years. I have had positive results, but they recently have been leveling off as I still have some bare spots where my hair simply won’t grow. Could this be because the hair follicles have miniturized to the point where they have simply vanished?

I would need to map out your scalp for miniaturization to determine an answer to your question, but it is not unusual for minoxidil to level off on its value over time.
