Up the dose. .5 MG. Don't listen to meme reddit science stating .25mg is enough, it usually isn't. I read in Korea that they prescribed it at .25 but keep in mind Asians are typically lower test. If you are European, .25 is dangerously low with risk of having unsatisfactory effects on hairloss. Try either 3 1mg per week or .5 every day. There are these 2 guys on YouTube who advise the first idea but I'd go with a consistent dose of .5. If that doesn't work then just try 1 MG or jump on dutasteride.
Keep in mind finasteride has varying degrees of success. About 90% see a stop in hairloss or slow down. But some don't respond at all.
