Before you choose to have surgery, please give medication a chance to improve your hair. Doing so will probably improve/ fill your crown and the quality of your existing hair. There are a lot of options. Some guys have had good results with oral minoxidil or finasteride. Some including myself have been experimenting with topical Dutasteride. After 6 months, reevaluate and then decide if you want to proceed with surgery. Dr. Arocha seems like a good doctor, but I would meet with him personally and ask to see some of his patients results that most resemble yours. Best of luck.
