Hello AI 7, first, we don't recommend getting a hair transplant for men who are under the age of 21. Since you are 25, you are suitable for a hair transplant in that matter, but we are always suggesting getting a hair transplant treatment when the hair loss process is stabilised.
Quitting smoking would be a good idea to have a successful hair transplant treatment.
You can get an FUE hair transplant with approximately 4500-5000 grafts. That would be enough to have a dense and natural look.
After the hair transplant, you can get PRP therapy to support your hair growth.
