I’ve Had DUPA Since My Teen Years

I have been experiencing DUPA-patterned thinning since puberty, if you can believe it. I had my thyroid checked at 15 (20 now) and apparently everything was in order. Classic MPB runs in both sides of my family but I haven’t seen any instances of DUPA, and both my brothers seem to have been spared this condition. I took propecia for a year and it did nothing.

Are there any leads on possible underlying causes of DUPA, since it has become rather apparent that it is not [entirely] related to DHT levels/sensitivity? Could I possibly benefit from a visit to an endocrinologist or other specialist?

I do not know if you will benefit from an endocrinologist or other specialist unless you have actually been diagnosed with diffuse unpatterned alopecia (DUPA) by a physician. Are you diagnosing yourself with DUPA because you have thinning of your hair? Some people do have thin hair, but that is not DUPA. There’s no underlying cause of DUPA that is known at this time, so nothing you can really be on the lookout for. We simply don’t understand the condition all that well.

I also do not understand why you would be taking Propecia without a diagnosis of androgenic alopecia. Are you self treating? At the least you need a good examination and a diagnosis.
