Been using Toppik

[noodles14]

for 3/4 years on my crown and am pretty happy with the results, but wondering if I should try to find a more permanent solution now before hair loss gets worse, or wait until that happens.

Could anyone advise if it is worth looking into a transplant now, or if something like rogaine is worth a try first? I have been using nizoral for years but not sure how effective that is or not. Pics attached are hair wet, blowdried, and with toppik.

So 3.5 years on its definitely got worse, although am still relatively happy with the toppik results. Sides of fin scare me tbh so have been thinking about rogaine, although also concerned any shed would leave the toppik useless and a big bald spot for a while? last resort is obviously a ht but not sure surgery should be my first move? anyway pics below are again wet, blowdried, and with toppik. any input would be appreciated.
