Bingo, you're correct.
Finasteride and Dutasteride (but not Flutimide of which I know less about but isn't in the same class of drugs) are 5AR inhibitors. 5AR are the enzymes responsible for the chemical conversion of Testosterone to DHT. By inhibiting 5AR it inhibits that conversion and hence lower levels of DHT.
However, in addition to that, it also produces Allopregnanolone and Tetrahydrodeoxycorticosterone, both neurosteroids which will also be inhibited by the same mechanism of action of the drug. Disruption of these chemicals in addition to DHT can cause numerous side effects such as brain fog, depression, anxiety, and other neurological effects. Some have reported these symptoms persisting for indefinite periods of time after discontinuing the medication.
I would recommend against pursuing the 5AR inhibitors until other options have been looked into.
For one, it may take a while for your hair levels to decrease after starting Spironolactone. I would recommend waiting at least 7 months or so. After that, assuming your testosterone levels are in female reference ranges, you may want to consider laser. If you can't, then these medications may indeed help you, but like all medications, they have risks.
