Finasteride

Finasteride is a medication used to treat male pattern hair loss in men. It works by blocking an enzyme that converts testosterone into a hormone that can shrink hair follicles, helping to promote hair growth. You take it as a tablet, with a recommended starting dose of one milligram once a day, and it usually takes at least three months of daily use to see results. It's important to note that finasteride should not be used by women, especially if they are pregnant or may become pregnant, as it can cause serious birth defects. Additionally, if you have liver problems, you should be cautious when using this medication, as it is processed in the liver.
