Propecia is an antiandrogen and operates by reduces type two 5-alpha reductase. Type two 5-alpha reductase is an enzyme that changes testosterone into dihydrotestostorones.
As such, Propecia reduces the levels of dihydrotestosterone (DHT) which is a vital for regulating hair follicle. To fully understand how Propecia works, one must understand the process of male pattern hair loss.
Male pattern hair loss is not a new phenomenon. All you need to do is have a look around your office or a local sports fixture to realise that, if you are having problems with androgenic alopecia, then you are not alone.
Male pattern hair loss concerns about half of all men by the age of 50. People can start losing their hair as early as their teens.
If you don’t start a treatment like Propecia soon after onset you could lose much of your hair very, very quickly.
Hair loss goes through a series of stages and Propecia works by stopping male pattern hair loss in its tracks.
There is a scale called the Norwood-Hamilton scale which can be used to examine what stage your hair loss is at.
The main cause of male pattern hair loss is the hormone DHT and, as mentioned above, Propecia has been proven extremely effective in tackling high levels of this hormone by blocking the enzyme 5-alpha-reductase.
In this way, you will start seeing the results of Propecia in a matter of months. In 50% of cases Propecia not only stops hair loss in its tracks it also increases the number of scalp hairs, which helps to “fill-in” thin and balding areas of the scalp.
Of course hair growth is a naturally slow process so it will take a natural amount of time to start seeing the effects of Propecia.
Propecia only works as long as the medication is still taken, so it’s important that once you start taking the medication you stick to it.
If you do, however, Propecia will bring a solution to the problem of male pattern hair loss for you.
Propecia has held up in many clinical trials. One study showed that 86% who used Propecia did not suffer any further hair loss; this was in comparison with 42% from the placebo-treatment group.
In the placebo group only 7% of men had improved hair growth, compared to 48% of men in the Propecia group.
