I recently shaved my head and began closely monitoring my hairline. There are a few follicles that stood out from the rest because they were isolated and a bit lower than the front of my hairline. I recently noticed two that had stunted growth and formed what resembled a blackhead. After “popping” them the hair has still not grown back. Do hair follicles have a dormant stage or does this signal that the follicles have died and that I am beginning to lose hair?
Read about hair cycling here. If you monitor your hairline this way, I would suggest that you (1) always lift your brow so as to see the highest crease and (2) collect serial photographs with your brow lifted. Good luck to you, as the quest may take a few years to understand what is happening to your hairline.
