In mid-feb, my husband was wrestling with a friend in our living room. His friend picked him up and accidently slammed him on the concete floor. My husband’s head hit the floor and he had a huge bump on his head. The swealling went down but he still has a bald spot there. Will his hair ever grow back?
I would expect that the hair will grow back within 6 months (or less) from time of the injury.
