Propecia (finasteride): Effectiveness As A Hair Loss Treatment, And Side Effects

Propecia finasteride is one of the most prescribed treatments for male pattern baldness which is one of the most common causes of male hair loss. Developed by Merck pharmaceuticals, Propecia was approved by the US FDA in 1997 as a prescription only treatment for male pattern baldness (androgenetic alopecia).

About Propecia finasteride and how does it work?

Propecia finasteride is found to be effective in 90% of men who have tried the treatment. The drug not only helps to prevent further hair loss but also stimulates the growth of new hair. To achieve the most effective results, Propecia treatment should be started in the early stages of male pattern hair loss.

The active ingredient in Propecia is called finasteride. The compound belongs to a class of medicines called type II 5-alpha reductase inhibitors. Propecia finasteride inhibits the natural conversion process of male sex hormone testosterone into dihydrotestosterone (DHT). Although DHT is an important sex hormone, in some men the level of DHT becomes quite high. When in excess, DHT shrinks the hair follicles in the scalp, eventually leading to the hair falling out. Propecia helps to lower the level of DHT in the body and thereby helps to prevent further hair loss.

Positive effects of Propecia

Propecia finasteride helps to normalise the level of DHT and help it stay low enough so the adverse effects of DHT on the hair follicle stop. By working this way, Propecia helps to normalise the hair growth cycle and in turn reverse the hair loss process. The results of the Propecia treatment are noticeable within 3 months of starting the treatment. In 5 years time, men may notice a head full of hair depending on what stage they started the treatment and how well their body adapts to the treatment. The effects of Propecia have been studied in a 5-year clinical study in which 90% of the patients reported a visible improvement.
