Dosing finasteride

Doc, i have a question, Does it happen usually that someone stops reacting to the current dosage and has to move to higher concentrated dosages. Ex, someone stops reacting to 1mg finestride and has to move to 2mg to keep seeing results. I am kinda scared of it, I started with 1mg per day, but later came across someone mentioning it, so I reduced the dosage to 1mg every alternate day, bcoz 0.5mg per day wasn’t available. Was it a smart move or me just believing in a myth?

The original Merck studies showed that the 1mg dose was the ideal dose for hair loss. Half that dose is 82% as effective, so taking a pill every other day is essentially half the dose and it should still be 82% effective in your situation.
