Hello the question i have is about my six year old son. He fell and hit his head causing a large bump. After the swelling went down we noticed his hair fell out in the same spot. Is this normal and should we be concerned? I greatly appreciate any feed back.

Any trauma on the scalp skin can force hair follicles to enter the telogen (resting) phase. The telogen phase may last up to 6 months, so you should expect that your son start growing the lost hair back in about 3 to 6 months in that area. I am assuming that there is no laceration which caused a scar.
