Propecia: Primary Causes of Hair Loss

Early Onset

Hair loss can begin as early as 15, and many young men aged 20 to 25 have already experienced the loss of self-esteem and the resulting embarrassment that baldness can cause. Losing one’s hair at 50 is disturbing enough. Losing it at 18, when a male is just emerging from adolescence, with all its pimples, shyness, awkwardness and hormone surges, is devastating. 

Everyone loses hair. Doctors agree that it is quite normal to lose 100 strands of hair a day. Since the average scalp contains abut 125,000 hairs, the loss of 100 is considered insignificant. More hair loss than that, however, and you are experiencing Alopecia. 

What Causes Hair Loss?

Hair loss is not just a male issue, of course, and 22 percent of women have the problem as well.  Propecia, the first clinically proven prescription treatment for Androgenetic Alopecia, or male pattern baldness, is not recommended for pre-menopausal women because it causes a specific birth defect in male fetuses.

There are a number of causes of hair loss other than Androgenetic Alopecia: excessive exercise, extremely high cadmium and thallium levels (which directly affect the nervous system), extreme dieting (the loss of vitamin K alone can reduce hair count drastically); smoking, stress (which leads to Telogen Effluvium, an episodic, non-scarring form of Alopecia), depression, radiation, Lupus (yes, men get it too), Warfarin (a blood thinner), and Hypothyroidism, which is less common in men than women, but still occurs. Additional causes of hair loss are chronic venous insufficiency (CVI) - which destroys not only hair but the follicles it grows from - and specific kinds of heart disease. In fact, studies have shown a definitive link between heart problems and hair loss, but don’t panic. Only a doctor can determine if hair loss is related to heart problems, and if you are losing your hair, a doctor’s office is the first place you should visit anyway to discuss options such as Propecia.

Treating Androgenetic Alopecia

Androgenetic Alopecia is diagnosed by the pattern of balding from the hairline back, and eventually including the entire top of the head (the vertex). In carefully controlled studies conducted in the United States, Propecia has been proven to re-grow hair lost to Androgenetic Alopecia in more than 65% of men, with almost 80% of men reporting a slowing of their original hair loss. 

Reporting from Japan, a group of researchers from Kitasato University, in conjunction with 47 medical facilities around the nation, have confirmed that Propecia appears to work in 90% of men who take the medication for at least six months. The report, published in the July 31st issue of Asia Pulse, noted that 92.2% of respondents said using Propecia reduced their hair loss, either substantially or noticeably. Since not all of the 380,000 respondents stayed on Propecia for the full course of the study, the conclusions are not definitive. However, the study suggests that men who use Propecia for long periods of time (up to 5 years) can expect both a reduction in hair loss and an increase in the amount of hair.

Banyu Pharmaceutical released Propecia in Japan in late 2005, and expects Propecia to reach sales of 10 billion yen this year.
