Loss of hair is common to both men and women worldwide, although women experience the problem lesser compared to males. Androgens hormones such as androsteinedione, testosterone and dihydrotestosterone are believed to trigger hair fall in men. These are all male hormones, but found in small volumes in women. As the primary cause of hair fall is sometimes believed to be common for both men and women, female hair fall is likened to androgenic alopecia or male pattern baldness by some experts. For the treatment of androgenic alopecia, Propecia is one of the most trusted medicines around. But this drug is not recommended for women, particularly those who are pregnant or expecting.

Propecia finasteride and hormones
Finasteride works by preventing an enzyme called 5-alpha reductase type II from converting testosterone into dihydrotestosterone. This hormone damages hair follicles in the scalp, which blocks hair growth and causes baldness. Propecia finasteride is a clinical breakthrough in treating male hair loss. It is available only on prescription. With regular treatment, you can also regrow hair and improve your body image. It is reported that the drug can stimulate hair regrowth in just 3 months. But some men may have to take the pill for up to a year to notice its effect on their thinning hairline.

Finasteride is not for women
Medical researches have unearthed that hair fall in women is caused mainly by an enzyme known as aromatase. Finasteride does does not have any effect on this enzyme. This is why Propecia is only prescribed to treat male pattern baldness or androgenic alopecia. It is not recommended for women who suffer from pattern baldness on the vertex or near the forehead. If you are pregnant, you should take extra precaution in handling Propecia pills. Usually the pills are coated for the safety of the people who handle them. But in case the coating is crushed, pregnant women are advised not to handle the pill.

Disadvantages of Propecia
There is no doubt that you can treat male hair loss with Propecia better than any other available prescription drugs. But still the effectiveness of this medicine is only limited to androgenic hormones such as dihydrotestosterone, testosterone and androsteinedione. This medicine can decrease a man’s sex drive and can even harm male fertility.

In case a man has low sperm counts, the Propecia treatment can further decrease the number of sperms and affect his reproductive capacities. Merck, the manufacturer of Propecia, has issued a warning that men using this medicine may experience a low volume of semen. But experts have also suggested that stopping the use of finasteride after 6 months of hair loss treatment can increase sperm counts significantly. Even though this is a good news, doubts still linger heavily over the medicine’s potential harmful impacts on man’s reproductive health.

If mishandled by pregnant women, finasteride can cause serious harm to newborns.

But in the end, the benefits of Propecia finasteride outweigh the risk factors. But it is advisable that you should talk to your doctor before using this popular hair loss medicine.
