Propecia

A man who is searching for the >best hair loss products needs to know know that the drug named Propecia contains a DHT blocker. How can a DHT blocker help to prevent hair loss? The chemical in Propecia that blocks the formation of DHT is called Finasteride.

Finasteride interferes with a particular biochemical reaction, a reaction catalyzed by the enzyme 5-alpha-reductase. The reaction catalyzed by 5-alpha-reductase leads to DHT production.
In the presence of DHT, that same chemical binds to the roots of hairs in the scalp. As the scalp hair in any man become covered with DHT they are deprived of valuable blood. In the absence of nutient-rich blood, the hairs in the scalp die and fall out.

The biochemical pathway described above can not be found in the scalp of an adult female. It can only be found in the scalp of certain older men. Men who have a large amount of the proper androgen hormone normally initiate the chain of reactions that lead to formation of DHT. A series of biochemical changes transform that androgen into testosterone.

Testosterone has two roles in a man’s body. First, it initiates the changes that change a small boy into a virile, adult male. Later, when that same male becomes older, the testosterone binds to the 5-alpha-reductase in the scalp. That binding action triggers the biochemical reaction that is responsible for formation of DHT which causes hair loss.
In the absence of Propecia, testosterone can combine with 5-aphpa reductase. Normally the mixing of testosterone and 5-alpha-reductase leads to formation of DHT. In the presence of Propecia, the biochemistry of scalp hairs undergoes important changes. Due to those changes, the hairs of the scalp can not produce DHT. In the absence of DHT, the hairs of the treated scalp enjoy a longer period of growth. This is a similar process to what Provillus and Procerin hair loss treatments offer.

Men must realize that any drug that acts to alter a particular biochemical reaction could have the ability to impede or accelerate other body reactions. Physicians are all to aware of that possibility. That then explains why any man who wants to try Propecia must get a prescription for the drug from his physician.

If a man finds that his physician agrees to give him a prescription for Propecia, then he must make every effort to follow the directions on the Propecia package. Failure to adhere to the directions on any prescription medication reduces the likelihood that that same drug should deliver its anticipated effect.
