Mine has definitely thinned, though I can't say if that's due to weight loss or due to going under anaesthesia several times in a short period of time (which can apparently cause hair thinning). That being said, my hair has always been very thick, so now it is a "normal" thickness...though I miss having crazy-thick hair!! I wonder if it will come back?
Congrats on the thickening, though! I agree that it could be due to better nutrition.
