How does it work?
Propecia tablets contain the active ingredient finasteride, which is a type of medicine called a 5-alpha reductase inhibitor.
Finasteride works by inhibiting the action of a compound in the body called 5-alpha reductase. This compound is called an enzyme, and is responsible for converting the male hormone testosterone into dihydrotestosterone (DHT). DHT is a hormone that can damage hair follicles and lead to hair loss in men who are genetically sensitive to it.
As finasteride prevents the action of 5-alpha reductase it prevents the formation of DHT. This decreases the amount of DHT both in the blood and the scalp and can lead to reversal of the balding process.
The medicine is taken by mouth to increase hair growth and prevent further hair loss in men with male pattern baldness. It may take three to six months of treatment before you notice a decrease in hair loss or increase in hair density. Continued use of this medicine is recommended to obtain the maximum benefit. If you stop taking it you are likely to lose any hair you have gained within 9 to 12 months.
