Hair loss -- PRP, Progesterone, Viviscal, Rogaine, Finesteride, Spironolactone
Hair loss can be stimulated any anything, any stress / genetics / hormonal or lifestyle change. I suggest you see an expert if you are concerned. Best, Dr. Emer.
Hairloss from weight loss is not uncommon in women with rapid weight loss. If the loss was over a month or more and it is not just 'water' loss, then it is unlikely that the weight loss caused the hair loss.
