Has anyone experienced very fast miniaturization of a follicle? I am talking one hair cycle. Back at the end of October, my derm asked me to collect my hair for an examination for a month. My hair bulbs back then looked fine, and my biopsy showed normal follicles. Flashforward to the beginning of January, my hair bulbs are basically so small, it is hard to see them on my fallen hair. I have no idea why it is so fast, has anyone experienced that?
