Propecia, also known as finasteride, is one of two U.S. FDA approved drugs for hair loss. Taken in the form of a pill, it is a prescription drug that is considered to be a more effective than its erstwhile rival, Rogaine (minoxidil).
The Benefits of Propecia
Propecia blocks dihydrotestosterone, the hormone thought to be responsible for male pattern hair loss. It also helps stimulate hair follicles.
The success rate for Propecia is very high. Around 80% of all Propecia users report a positive change when it comes to their hair. For some users, Propecia stops the hair loss process. In others, it goes beyond that – it actually causes more hair to grow.
You will most likely see the effects of Propecia after three months of regular use. Once you stop taking the drug, however, you will lose what you have gained over the course of one year. It is recommended that you use Propecia on an ongoing basis.
Propecia and Proper Caution
Of course, no drug is free from side effects. According to Merck, which markets Propecia, around 3-6% of users will experience sexual side effects, usually a lowering of the libido or decreased fertility. However, the effect is temporary and the user will soon regain his normal drive.
Another thing: Propecia is currently considered safe for men only. Clinical tests have not been performed on women. Pending such a trial, it is best for women to use other hair-loss drugs such as Rogaine. Propecia has been known to cause birth defects when women of childbearing age use them.
