I Was Told I Should Start Finasteride But I Am Norwood 1

Hi, I went to see a ISHRS physician 7 months ago because I was concerned about family history. He told me he didn’t see anything but told me to come back in 6 months. I recently went back and he examined my crown and mid scalp and found miniaturization, however I am still a NW1. He confirmed I have MPB, and gave me Finasteride. My question is, provided finasteride works, can I expect to keep this hair for a while? My thinning is unnoticeable to the naked eye but is present on a microscope.

I think you should ask this to your doctor since they examined you. If you have signs of male pattern balding (MPB), then finasteride 1mg (Propecia) is a medication to treat this condition. The thinning may not be detectable to the naked eye but it may be present under a microscope with signs of miniaturization. This is why we have always advocated the miniaturization (microscope) test. You can also consider a Bulk Measurement as well which is fairly accurate in detecting very early balding using the HAIR CHECK instrument. It is not necessary if you already have the diagnosis, but it can still document the progress of the hair gain or loss.
