Well, I found someone that asked the question because they had gotten burned on their head, and here was the doctors response.


You burned your scalp 2 months ago and as of yet you have not grown any hair there. You have a blister on the burned area, which means you had a 2nd degree burn there. As a general rule, a 1st degree burn is superficial and does not involve hair follicles, so they usually don’t cause permanent hair loss. 3rd degree burns are deeper and usually damage the entire hair follicle and cause hair loss, and they may also damage nerve endings and cause numbness in the area.

In your case, with a 2nd degree burn they are in between and may or may not damage hair follicles permanently. You have to wait for about 6 months and by then if you are not growing hair in the bald spots you may want to consider hair transplantation. At that time you could be evaluated to see what could be done for you if the need is there. For now though, my suggestion would be to just wait it out.
