Miniaturized hair shedding on finasteride

I’ve been on finasteride for about 4 months now. Shed began about a two months ago, nothing too out of the ordinary. Shedding miniaturized hair everytime I brush or shower. I was wondering, how long is this gonna last? Does one reach a point where the only hair you lose are terminal hair?

You need patience. Finasteride doesn’t always work so you and your doctor should re-examine your personalized Master Plan if it doesn’t work by the 6th month.
