Cyst Removal on Head Causing Female Hair Loss?

i have been on the depo shot for about a year now and have noticed that my hair on the top of my head is thinning. now i didnt notice this until about august i think it was after i had a cyst removed from my head. it is by the area where it was removed but all they did to remove it was make an incision and it was tough coming out so they had to pull and dig a little. my question is could that removal of that cyst have caused this and in either case, will it grow back?

Any procedure in the scalp may trigger hair loss at the surgical site. Two main factors may cause this local hair loss:

1. Shock loss: If you are predisposed to balding, you may have already had miniaturization to some degree and the surgery on the scalp may have only facilitated the process of hair loss. This phenomenon is called shock loss, and it may or may not be reversible. It varies per person.
2. Undermining the edges of incision: In order to remove a mass or cyst from the scalp or sometimes to reduce the tension of the skin edges, the surgeon may cut some of the hair follicles. Dissection of hair usually results in permanent baldness in the affected area. This baldness in a scarred area is similar to the hair loss that patients get after a craniotomy or scalp trauma.

My suggestion is to wait it out for 6 months. If the bald area doesn’t grow hair during this period, the baldness may be permanent. At that point, if the location of the scar is noticeable, you may want to see a hair transplant surgeon. The treatment options for this condition will be either to primarily remove it if the scar is small enough, or to use hair transplant to fill the bald area if it is too large.
