Bald Spot Growing After Getting Hit with a 2×4 Years Earlier

My boyfriend is 26 years old. When he was a teenager he was hit by his brother with a 2×4 on the back right side of his head. A scar was there after healing, but only about an inch long. A small bald spot remained there also. About 2-3 months ago we noticed a much larger bald spot there. It is about 2 1/2 inches across now. It is very smooth, there is no hair on it at all. Do you think he needs to see someone about this? I am worried there is something wrong. He just tries to forget about it and is hoping it does not get any worse. I cannot do that. What do you suggest? Thank you

If you or your boyfriend feel there is something wrong, then by all means go see a doctor. I viewed the photo you sent and I doubt a new bald spot like that can appear many years after a scarring injury, but it is clearly there… and there for a reason. What that reason is though, I couldn’t say. There are many other medical conditions that may be causing the balding, but a diagnosis-by-photograph is often very difficult to make. Unfortunately, my only suggestion is to have your boyfriend see a doctor for an in-person exam.
