Advice on hair transplant

[Alvin23]

I am scheduled to get 1300 fue grafts in a couple of weeks and am just wondering if there is anybody out there that was in a similar case. I am 24 years old and have been on finasteride for 1.5 years now. Hair loss has seemed to stop since I have started finasteride. I am not looking to get a new hairline as much as I would like to add density to the hairline I have currently. Is this a reasonable expectation?
