Lost almost 70 lbs, now I'm losing my hair too?

happened to me when my calories were too low in late November, I immediately increased them and it fixed itself less than a month - now it's getting thicker and longer than ever

Yes; tight ponytails and braids cause traction alopecia (pulling hair) Over time, the hair stops growing back, or becomes very thin, when the follicles are damaged or the scalp develops tiny scars from the pulling.
