I have been on finasteride ( 1 mg ) for the almost the last four months and I guess it's a little early to predict whether it is working or not. However, I don't want to give hairloss as good a fight as I can. So I was thinking if it would be more effective to use 2.5 mg finasteride ( or for that matter 5 mg). Also are there sides involved in switching from 1 mg to 2.5 mg ? Please let me know soon. Thank you.
