During my 12 week class we were told that we could experience hair loss after surgery but its something that will grow back and that makes me extremely scared. I have Dreadlocks and they are much of my identity and culture. I just keep playing in my head my locks falling out and me just holding them and crying. lol a bit extreme but so true. So has anyone experienced hair loss?? And if so how bad was it and was it noticable
