Welcome to HealthcareMagic.
First of all you are doing very well (hair loss reduction of 80% in just 3 days is wonderful).
As for the frequent urination
, it is not listed as one of the side effects. I have treated hundreds of patients with finasteride
(finepecia), but hve not encountered this problem.
This frequent micturition may be due to urniary tract infection or diabetes
Please get your urine tested (routine microscopy and culture) and get your blood sugar done.
