The drug propecia is a prescription hair loss medication designed mainly for men with mild to moderate hair loss. The effects of hair loss and propecia were studied in several clinical trials, and propecia was found to be better than a placebo.

Men of all ages use it in combination with minoxidil to achieve a hair loss strategy that both halts hair loss and encourages new growth.

Scientist has recently discovered that men who suffer from male pattern hair loss have an increased level of a substance called DHT in their scalps. Both PROPECIA and its generic form block the formation of DHT and in this way appears to interrupt a key factor in the development of male pattern hair loss in men.

Propecia works by treating an underlying cause of male pattern hair loss by inhibiting the production of DHT, which is believed to be a major cause of hair loss. The enzyme Type II 5-alpha-reductase is involved in the production of DHT. Propecia inhibits the action of Type II 5-alpha-reductase, thereby decreasing DHT concentrations in treated men by approximately 60 percent.

This medication is available in the strength of 1mg. With regular usage of Propecia, you can see visible re-growth within a span of three months.
