Has anyone been measuring this consistently during their shedding period? Could you share with us how much your measurements changed? I have been shedding for over 15 months now and my ponytail circumference is around 3.2 inches not including bangs. I never measured it before, but it's definitely less than I normally had, which would be around 5 inches. I've been getting regrowth (but not enough regrowth) and I just want to get an idea of how much density people actually lose and get back.
