My hair stills falls out easily when finger combing, shed well over 100 daily after 3yrs, w diffuse thinning throughout; accentuation at temples. I've seen gains/losses, and some regrowth changing from mostly thin to thicker diameter and darker. Looks similar every year but perhaps more flyaway now. The right side is much less dense than the left. I don't have a wide center part or scalp showing. If it is DUPA, is it easily distinguishable from CTE or TE w/ only a scalp exam? Is DUPA common?
