Does taking dutasteride and finastride together cause more hair loss/shedding? Does dutastride cause more hair loss?

im 22yo with male pattern baldness, i been taking finasteride(in morning) for two years,it made me lose less hair on average day, but still i lost a lot of hair, so i decided to add dutastreide to my regimen by taking it at night. the first month everything was ok, but in the seconed month i noticed more shedding than normal. i went to two hair specialist docs. one said perhaps i'm under stress period and the second doctor didn't give me an answer.so i turn to you, do dutasteride cause shedding?
