Propecia is an oral prescription drug which is approved by the FDA. Propecia is one of the most popular drugs used for treating mild to moderate male pattern hair loss, particularly on the top and mid-scalp area of the head. In small doses, this drug is also used to treat prostatic hyperplasia, while larger doses are recommended during the treatment of prostrate cancer. A number of clinical trials have proved that in most cases, Propecia can successfully prevent further loss of hair, while in some men it can also lead to hair re-growth. However, results do vary depending on the severity of the case, and it may not be possible to re-grow all the hair you have lost.

Does Propecia live up to all the hype?
Propecia is available in the form of a pill and contains 1mg of the drug called finasteride. It is manufactured by Merck & Co. Inc. The benefits of Propecia are well documented by a series of clinical trials. Most men suffering from hair loss reported visible improvement after a course of Propecia, either in the form of re-growth or stopping of hair loss. However, in order to be effective, the drug needs to be taken every day for a period ranging between 3 and 6 months before results show. And if you want to retain your re-grown hair, you need to keep up with the course.
How does Propecia work?
One of the major reasons why some men are affected by male pattern baldness, known as androgenetic alopecia in medical terms, is excessive levels of a chemical called DHT in their scalp. DHT shrinks hair follicles so that they are no longer visible. Propecia helps in reducing DHT levels to a significant extent by inhibiting its formation. Thus, the affected hair follicles are prevented from further shrinking. Finasteride, a drug that was originally used in the treatment of prostrate cancer, is the main component of Propecia. The drug is generally prescribed in doses of 5mg and is particularly successful in combating hair loss in the crown of the head.
