What Causes Bald Spot On Head After Taking Treatment For Cyst On Scalp?

Hi I just recently had what i believe to be a sebecaous cyst or boil on my scalp. I applied warm compresses and used some bactroban ointment that my derm gave me for two weeks. I'm also currently on doxycycline. I see my derm due to my acne and scalp eczema. After the cyst subsided it left a small little bald spot in the area that the cyst was present. Is it possible that this small bald spot is temporary due to trama to the hair follicles from the inflamation? I thought my derm had told me once before that sometimes a localized infection such as a scalp sebeacous cyst can cause a type of temp hair loss in the area? Have you ever heard of this? Is it possible? if so, providing there's no scare tissue or damage done to the follicle, will it grow back? I'm 28 years old, 6'2, and weigh about 235 pounds.
