I had a small hair transplant to hold my frontal area (photo)

You have a Norwood Class 3A pattern of balding reflecting significant frontal recession. There is no such thing as a minor hair transplant as you should have put the hair back where it belongs and tackle the transplant the right way so you don’t have to maintain your recession. Any doctor who did a minor hair transplant just made you into a hair transplant addicted person who will have to finish what was started sooner or later because if you lose hair behind the hair transplant you will have an island of transplanted hair, a bald area and then the hair behind it that is yours. Your call of course to finish what you started.
