Propecia is a medication that is used to treat male pattern baldness. It contains the active ingredient finasteride, which works by blocking the conversion of testosterone to dihydrotestosterone (DHT) in the scalp. DHT is a hormone that is linked to the development of benign prostatic hyperplasia and male pattern baldness. Finasteride 1mg is the standard dose used for treating these conditions. It can be prescribed by a doctor or purchased overthecounter at a pharmacy. However, it's important to note that finasteride should only be taken under the guidance of a healthcare professional as it can have side effects and interact with other medications you may be taking. If you decide to buy Propecia online, make sure to choose a reputable online pharmacy to ensure you are getting genuine medicine. Also, consult your doctor before starting the treatment.
