As Melvin mentioned, you should be consistent with your finasteride and minoxidil usage. If you start getting side effects from the oral finasteride, try lowering the dosage and if you're still getting side effects, switch to topical finasteride. I'm starting to recommend my patients use oral minoxidil as well since it's been shown to be very effective. Consult with your physician first.
You should consult with the surgeons recommended on here:
