hair loss
I've tried very hard to keep my protein levels up since surgery and I also began taking 5 mg of biotin about a month before surgery. I am 7 months out and have not had any hair loss.
Now, 3 years ago when I went through shoulder surgery and lithotripsy twice, all within a six month period, I went through some major hair loss!! I really believe the biotin and protein have kept me from losing hair this time.
