Myotonic Dystrophy and Hair Loss?

Hello, I am currently a 20 years old male, with extremely fast paced MPB in the front region. There is no extreme history of MPB in my family, although my dad and his brother are both above 50 and both thinning.

Anyways, my question is, my father has miatonic dystrophy, which of course is a genetic disease effecting muscles. I have never been tested for the disease, however I was looking up symptoms and one was listed as possible frontal hair loss at an earlier age due to hormone changes. My dad of course, did not experience this. I had just got a prescription from a dr for proscar, and was wondering IF this was the case, would there even be a point to taking it? I write to you because none of the physicians I’ve seen seem to know what they are talking about.

Hair loss in the great majority of men (especially frontal hair loss that occurs in a specific pattern) is due to genetics. It does not matter if your father or uncle didn’t see male pattern baldness until their later years, as the gene can also come from your mother and can even skip generations.

Though myotonic dystrophy can cause hair loss, I am a bit worried if none of the physicians can explain this to you before you were prescribed a medication to treat genetic hair loss in the first place. Was your doctor not aware of your family history?
