Though Finpecia starts blocking the creation of dihydrotestosterone as soon as it arrives inside the body, some time is required for the hair to begin its growth. You have to remember that strong and healthy hair grows for about 1 centimeter a month, that’s why only in some time you’ll be able to see and feel the positive result.

Medical researches worked out the plan, which says that Finpecia has to be used every day for three or even more months, for at least to stop the hair loss or to renew the hair growth. 

In six months you’ll be able to notice that some new hair begins to grow instead of the lost. And this hair is really strong and healthy. But in case there are no results after 12 months use, it seems that you shouldn’t use Finpecia anymore, because there probably won’t be any positive effect.
