I have a keloid on the back of my head. I've been getting the steroid shot for a year and I just want to have surgery (Photo)

Surgery may not be your best first option. I would use a combination of injections, lasers, and skin resurfacing to help improve your scars. Best, Dr. Karamanoukian @kareplasticsurgery on Instagram

Steroid injections can only help to reduce the inflammation and symptoms of discomfort. But they won’t actually get rid of the bumps. If your condition is entirely due to ingrown hairs and the bumps are small and short, it is possible to undergo laser treatment to epilate (remove the hair shafts) which may flatten the bumps significantly. If you are experiencing a more complex manifestation of Acne Keloidalis Nuchae (AKN), surgical removal will be the best way to get rid of the bumps once and for all. Nonetheless, you should have your condition diagnosed to clarify if your bump is due to AKN, general folliculitis, or other conditions which may be benign or life threatening. 

Thank you for your question and I am sorry to hear of your keloid issues.  There is a condition termed acne keloidis nuchae which can develop after a hair clipping which is a bad case of ingrown hairs causing repeated bouts of infection and scarring.  This is most commonly seen in the african american population and requires surgical excision of the area.  Be seen by a board certified reconstructive plastic surgeon for appropriate diagnosis and treatment.
