I have a birth mark in my head and its a bald spot. Is there a way i could get it removed or? (photo)

This can easily be done under local anesthesia and is very commonly performed.  There is always risk of some hair loss around the incision which is uncommon and usually temporary if it occurs 

Without examining your scalp, it appears that your birthmark represents an area of cutis aplasia.  It is most commonly seen where the hair cowlick of the scalp.  It can be removed surgically, often under local anesthesia. While it has been associated with several genetic conditions, it is most commonly seen in people with no other medical issues.

Birth marks are classified into vascular and pigmented lesions and it is difficult to determine the type of "birth mark" this is in the photo. If you noticed any changes in it recently such as enlarging, ulcerations, or pain you should have it evaluated soon by a physician.  You "mark" does appear to be small enough that you could have it excised and the area closed with a suture line.  The bald patch would be gone, but you have would have a linear scar that would not have hair but could be easily concealed by the surrounding hair as long as you keep the your hair with some length.  This can be performed under local anesthetic or general if you prefer.  Depending on the exact margins and the amount that needs to be removed, it may need to be performed with multiple excisions to avoid tension on the closure and widening of the scar.  Please seek a certified physician in your area to assess the mark and discuss the procedure details with you in person.  Good luck and I hope this helps.
