Male pattern baldnes: Only time will tell whether or not you have male pattern baldness. Drug options include finasteride, taken as a pill, and minoxidil which is applied to hair follicles (not hair strands). But even then, medications are only indicated for specific types of MPB. Check w/your Dermatologist or Hair Transplant Surgeon to make sure it's not due to infection or inflammation. Maybe check dihydrotestosteron
