My Son Has Hair Loss Around a Cyst

My 12 yr old son had an infected cyst on his scalp which has caused a penny sized bald patch. Our doctor said his hair should grow back if left alone, but I am wondering if the cyst needs to be removed to allow the hair to grow back. The painful swelling of the cyst is gone down and there is just a soft jelly like lump where the cyst was. Can you tell me if his hair is likely to grow back without any surgery. Thank you.

I cannot tell you anything different than what your doctor has already told you. Hair should grow back if left alone. If it does not grow back there is an option for a hair transplant surgery to address the small bald patch. Excision of these cysts may be appropriate if it returns infected again.
