Remedies for a Bald Spot I Got from an Infection?

Hello. When I was in 7th grade I contracted an abscess on the back of my scalp resulting in inflammation and pus and as it healed it left a bald spot. I thought it was from the dirty wrestling mats but never knew exactly where i contracted it. I am 29 today and hair still does not grow in that spot. What are some remedies or things i could do to grow hair back in this spot.

It would depend on the size of the spot to see if it could be excised. A hair transplant would solve that problem. I highly doubt medication would help you in a case like this.
