I agree with subrock in that when they fall out during the day, they probably get stuck in there. So when I detangle in the shower (which is the only time I do it) I'm probably pulling out the hair that I would pull out normally plus some extras that were just hanging out in there.
I lose quite a bit too. I think it's just shocking because we see them all at once.
2b/3a, primarily use Jessicurl and DevaCurl products, Curls Hair Tea conditioner and various gels. I'm modified CG-ish since 5/04.
