Understanding Male Pattern Hair Loss (MPHL)

The more you know about your MPHL, the better decisions you’ll make.
Male pattern hair loss (MPHL) is the most common form of hair loss, representing close to 95% of all cases of hair loss in men. And about half of all men experience MPHL by age 50. So if you have MPHL, you’re certainly not alone.

You’re probably very familiar with this type of hair loss. It can begin with a receding hairline, slow balding at the crown, or both. It is typically a progressive condition—left untreated, the hair loss will likely continue. By the time you may notice your hair loss, 50% of your hair may be gone. That’s why it’s important to start taking PROPECIA as soon as possible, to help limit or stop further hair loss and possibly regrow some hair.

Scientists believe that MPHL is inherited from either side of the family and that a chemical called dihydrotestosterone—more commonly referred to as DHT—is a key factor in hair loss.

DHT is a substance in the body that can shrink the hair follicle until it no longer produces visible hair. Scientists believe DHT and family history are key factors in hair loss.

Throughout this section, you will learn more about MPHL, its causes, and stages, and what you can do about it.

Important Information About PROPECIA
PROPECIA was developed to treat mild to moderate male pattern hair loss on the vertex (top of head) and anterior mid-scalp area (middle front of head) in MEN ONLY. There is not sufficient evidence that PROPECIA works for receding hairlines at the temples.

PROPECIA is for the treatment of male pattern hair loss in MEN ONLY and should NOT be used by women or children.

Women who are or may potentially be pregnant must not use PROPECIA and should not handle crushed or broken PROPECIA tablets because the active ingredient may cause abnormalities of a male baby’s sex organs. If a woman who is pregnant comes into contact with the active ingredient in PROPECIA, a doctor should be consulted. PROPECIA tablets are coated and will prevent contact with the active ingredient during normal handling, provided that the tablets are not broken or crushed.


Biostim is Propecia, but without the side effects.

The most common form of hair loss is genetic. Androgenetic alopecia occurs in approximately 60% of men and 10% of women in the U.K. However, if you are a sufferer you do not have to simply live with it as your parents and grandparents may have had to. You can take an active step today and discover Biostim, the new, highly effective hair loss stabiliser and hair regrowth stimulant available directly from our laboratories.


In clinical studies for PROPECIA, a small number of men experienced certain sexual side effects, such as less desire for sex, difficulty in achieving an erection, or a decrease in the amount of semen. Each of these side effects occurred in less than 2% of men and went away in men who stopped taking PROPECIA because of them.

You may need to take PROPECIA daily for 3 months or more before you see a benefit from taking PROPECIA. If PROPECIA has not worked for you within 12 months, further treatment is unlikely to be of benefit.

PROPECIA can only work over the long term if you continue taking it. If you stop taking PROPECIA, you will likely lose any hair you have gained within 12 months of stopping treatment.

Although results will vary, generally you will not be able to grow back all the hair you have lost.

Know the facts. PROPECIA is available by prescription only, so the best thing to do is talk with your doctor.

You are encouraged to report negative side effects of prescription drugs to the FDA. Visit www.fda.gov/medwatch, or call 1-800-FDA-1088.
