Male Pattern Baldness
From LoveToKnow Hair
Male pattern baldness is the most frequent form of hair loss and affects millions of men throughout the world. There is no known prevention for this condition, but knowing how it occurs and what can be done to slow the loss can help many men adjust to this very obvious sign of aging.
Causes of Male Pattern Baldness
The principle cause of this familiar baldness – technically called androgenetic alopecia – is heredity: fathers and sons often share similar baldness patterns. As men age, their hair follicles constrict, eventually growing shorter, finer hair and eventually ceasing to produce hair altogether, even though the follicles remain active. Because those follicles are still viable, there are a number of restorative products that seek to stimulate hair regrowth, though with limited success.
There is no predetermined age for the onset of baldness. Some men may have a receding hairline as early as their 20s, while others may not see visible recession until their 50s. While genetics is believed to be the primary factor determining whether a man loses his hair or not, there are several conditions that may cause accelerated hair loss, though the direct correlations are still being studied. These conditions include:
- Diabetes
- Obesity
- Prostate Cancer
- High Blood Pressure
- Low Testosterone Levels
In some studies, male pattern baldness slowed as these conditions were corrected, though how the two were connected is still being determined.
Typical Pattern
The classic baldness pattern begins with a receding hairline forming a characteristic “M” shape with a peak reaching down the forehead, combined with a thinning crown or bald spot at the top and back of the head. As the condition progresses, the two bare patches may meet, leaving only a ring of hair from one sideburn, across the back of the head, around to the other sideburn. At first, the balding areas may still have fine “peach fuzz” type hair in white or light gray shades, though eventually all hair growth ceases.
Women can also be afflicted with androgenetic alopecia (androgenetic is related to the word androgynous, meaning without sex differentiation), though they do not exhibit the same pattern of progressively complete baldness. Instead, the hair typically gets thinner and finer over the entire head, and small patches of baldness may appear in extreme cases.

TmplKnght - You're right, testosterone does play a tremendous role in baldness, but there are other factors as well. As with any genetic trait, the thickness and pattern of one's hair is determined by many different factors. Thanks for your comment!
-- Contributed by: MayntzBaldness is caused by the testosterone hormone or more specifically DHT. It isn't to do with contricting folicles. Hair growth occurs in cycles; a growth phase and a rest phase. Each folicle has its own cycle and they are not in sync. When we have a full head of hair, the growth phase is longer than the rest phase, but during baldness, the growth phase is short and so over all we look bald. The folicles still produce hair, but it is very small and has no pigment (translucent, not white).
