The Hairs I’m Losing Are Thin and Short

The hairs I see fall off during brushing are thin and short, between 1 and 3 inches, as compared to my ‘normal’ hairs on the side and back of my head. Is this an unmistakable indication of miniaturization and evidence for MPB? If Propecia and Rogaine are working (I’ve been on them for a year), should I expect to see increase in thickness and length in those fall-off hairs? Thanks

Hair loss does occur on Propecia and it could be ‘accelerated cycling’ of your existing hair. That being said, I don’t know what is happening to you, since there is no way for me to tell over the internet.

When people lose hair, the hair may be lost early in a cycle, but there is no way to tell. When hairs are miniaturized, they frequently slow down their growth rate and may just start growing in the beginning of its cycle when the “genetic axe falls”.
