How long will it take for a combination of Finasteride and Minoxidil to work?

I would recommend you to use Minoxidil and Finasteride 1mg for 3 months and regarding to your results, if you are satisfied you can keep taking them for another 2 months. There should not be a problem to take the two tohether, although make sure you are not allergic for them at first. 

İt takes 4-6 months for finasteride and minoxidil combination to work . you should be patient and go on to treatment for a couple of months  without care of initial shedding . 

Most hair loss treatments take 6-9 months to see results. Shedding is normal in the first few months. About 25 % have a response to minoxidil. 80-90 % to finasteride (stopping loss or regrowth). Continue close follow up with your physician.
