I am experiencing hair loss and not sure what to focus on as the cause. I am 40 years old, white female. I had gastric bypass 6 years ago and lost 100 lbs. I gained back a little after having my third child 3.5 years ago. This past September, I started back watching what I eat and walking every day. I ve lost 40 lbs since then. I also deal with anemia and have heard that can lead to hair loss as well. It s not falling out in clumps but definitely shows up when I comb my hair and on my pillow when I wake up..(6-8 strands). It s just concerning because I can tell what used to take wrapping a ponytail around twice to get all my hair up, now it takes four times...I m not sure what to do.
