@cyndi2013 I was going crazy the first three months post TKR with the hair loss and the long strands covering my clothing and filling the shower drain. Guess it was a way to get me to bend to clear the drain. I now have the little hair sprouts returning and the shedding has stopped. It was as bad as post pregnancy. You are the first person who has talked about this undisclosed side effect. My hair has always been straight so I assume that is what is growing back. Thank you for your post and sending wishes your curly hair returns.
