It’s a good idea to try meds because you’ll get a better idea of what you can get with a hair transplant. If the meds work and you get some growth without having side effects then you will need less grafts and you may be able to go a little more aggressive with density or where you create the hair line. If the meds aren’t working for you, or if you get side effects, or just decide you don’t want to stay on them long term then you’ll know you need to be more conservative with density and the hair line design.
