Yes, losing hair is common. The body goes through the shock of the procedure, and the aesthesia, the changes etc. about
three or four weeks after the surgery, I looked like a radiation case. My hair was falling out in handfuls.
The part on my hair was almost an inch across, with sort of stray hairs. I was horrified! My dermatologist reassured me that the hair would grow back, and it did. I got it cut really short until it changed its mind! Hang in there!
