Pressure Hair Loss?

I am a 31 year old female. I recently had 2 major surgeries on my back which required me to lay on my stomach in the OR for about 8 hours for both procudures. after which I noticed a spot on my forhead that hurt. Actually everywhere my body was touching the operating table hurt because of the amount of time and repetative movement involved in this very long surgery. 2 weeks after I notice the hair gone from that spot in my forhead. It no longer hurts but I figure with it being a month since the surgery that I would see it growing back by now. The area is still shiney and seems to be getting bigger (this could be my imagination).

Pressure hair loss does occur. Usually if the hair is healthy to start with, it will reverse. The shine you are seeing reflects the acute loss which will eventually disappear when the hair returns after 3-6 months from the date of the injury.
