A consult with the doctor is a good idea. From what you described you sound like a good candidate for FIT. Most people that are candidates for HT are candidate for FIT. Actually even some people that are poor candidates for traditional HT surgery are still FIT candidates.
Your age is working for you. Your stable hair loss is too. And most importantly, you have realistic goals. Hairline/frontal reconstructions are quite common.
Understand that you can still lose hair in your crown on the meds. So after you get FIT you may continue to lose hair. You will still have a natural looking pattern of hair loss though. At this point you can 1) opt for another session, 2) enjoy the full front and let the back go, or 3) clip your hair very short (this is possible with FIT as scarring is far less visible). Also hair cut short can give an illusion of more hair.
The doctor will be able to predict a worse case scenario for you during consultation. This should give you a clearer picture of where your hair loss is going and give more information to think over.
Glad the meds are working for you
