Sorry to say but you’re way past the point where medication can do anything for you LOL
I don’t even know why this forum is hellbent on advising medication as if it’s going to make a difference and suggesting anyone that comes here to waste another year of their life on medication then another year that these hair surgeons make him waste on a waitlist. Literally there was a NW6 at 22 years old and the forum ganged up on him telling him oh no don’t get a hair transplant you’re so young lol, the guy was like let me enjoy my life if I waste my 20s with this bald head, what the hell do I do with hairs in my 30s? There’s few Casanovas here who pull teenage girls in their 30s and waited 5 years for a HT but he knew he wasn’t one.
The only reason you should take medication (finasteride) is to stop progression to NW7. That’s it. You’re not going to grow any hairs, your hairs are clearly dead. You can try Minoxidil or microneedling or onion juice but if medication grew hairs, there wouldn’t be any hair transplants. You should absolutely not use medication and wait for a year giving up on HT thinking you are going to become a NW3 or NW2, I can only LOL at that. And after a year when you book a HT they will make you wait another year
My advice is to get a HT asap and enjoy life. You’re 28 and NW6, you will need two surgeries, expect full head of hair results in 3-4 years depending on clinic wait times. The top popular clinics have wait times in excess of 1 year now, even the Turkish clinic wait times are reaching 1 year. A year later I imagine they will be 1.5-2 years like most European/US clinics. Then hairmills are the only places that can take you
