Finasteride is mainly used for the treatment of male pattern baldness and benign pro-static hyperplasia. FDA's approved dose is only 5 mg once a day and if it is increased that level it may affect you inversely. Recently I done a hair treatment from Canadian Hair Transplant center (chtc.ca) and they suggested me no to use this in an increased level. Finasteride have many side effects and it concerning an increased risk of prostate cancer. So it's better to consult any hair treatment clinic before you use this one.
