At the age of 26, I noticed frontal hair loss along with thinning hair. I tried Nizoral shampoo, and it wasnât entirely futile, but it could not work well for my frontal hair. I have heard a lot of things about Propecia, and its efficacy in treating hair loss, therefore, I want to know from somebody, who has already used propecia, about its effectiveness for a young woman of my age. Please help!
