I think you should take both Minoxidil in addition to the Finasteride you are already using. Minoxidil takes some time to notice if it is working or not, and Finasteride will do most of the work (for androgen alopecia).
In my own opinion, I really feel that topical Progesterone does the most work. I am a man in his fifties, and when I used a 2% topical Progestserone solution, I had virtually no hairloss at all. I have been balding since my twenties.
In the United States, you can only get a 1% Progesterone prescribed solution from hairregrowthmd.com. Medicalwellness center is much cheaper, but they only do a maximum of 0.25%. (* Disclosure, I received the 2% Progesterone solution from hairregrowthmd, and then their doctor, because they went out of business in 2018, and were bought by a different owner). Hairregrowthmd is better, but they are much more expensive.
If you don't live in the United States, you probably get it from their because they have a*** prescription laws (and without saying, are not foreign worker friendly at this point in time.. for other reasons).
That said, Minoxidil does not really tamper with your hormones. Finasteride has a short half life, and while it is active, it cuts down 70% of your DHT levels (which you don't need for strength building, because testosterone does that).
Dustasturide has a long half life, although it does cut down more DHT. I tried Dustasteride and had ED for a month after I quit it. That went away though.
