Hello, I started taking Finasteride 1mg (Brand) 3 years ago and had amazing results. I lost coverage through work so I decided to take the 5mg pill and divide it up into quarters (1.25). Within 2 weeks my hair started shedding extensively, after 4 months my hair was still shedding extensively so I switched back to the 1mg dose and after anohter 4 months of the 1mg my hair is still shedding. And I have lost all my results I gained from taking it for 3 years prior. What should I do?
