Shedding from finasteride, how long does it last?

Normally how long does it take for the anti-androgens to push all the telogen hairs out and replace them with anagen hairs with a bigger diameter, thicker, denser, which is what the increased shedding phase boils down to being afraid.  My mother’s a dermatologist and told me to wait for 6 weeks for it to stop and if it takes longer than that and the shedding doesn’t stop then it’s abnormal and I should try another drug

Ignore the shedding with finasteride because it eventually goes away and the benefits then come on. Sometimes the shedding is not shedding but a rapid genetic hair loss being expressed and in that situation drugs like finasteride work to slow or stop the loss
