Help with choosing treatments (18M)

I am a diffuse thinner. I am on topical (fin 0.1% + min 5%), 2ml a day since November 2024. My hair hasn’t gotten worse, I would say it did get very slightly better. I would guess I am a topical minoxidil non responder. I see two options:

1. Topical minoxidil with tretinoin; readily available in my country. But applying two topicals a day seems very tedious. Would I get okay-ish gains if I did it once or twice a week?
2. Add oral minoxidil. The issue with this is that I can’t get topical finasteride which does not have minoxidil in my country. So I’d be using both topical and oral.

Oh, and I also plan to add topical dutasteride 0.025% maybe once every two weeks. It’s pretty inexpensive and easy to get.
