That percentage rate increases by 10 points for every decade. Other authoritative sources say that 3 in 5 men will be affected by male pattern baldness by the time they reach their 50s.
In the 1940s, an anatomist by the name of Dr. James Hamilton published two papers in which he observed that hair loss was dependant on 3 factors: male hormones, genetic predisposition and age. The most important of these 3 factors being androgens, the male hormone. However, it wasn't until the 1970s or 80s that scientists fully understood exactly how male hormones caused baldness. With advancements in technology, they were able to observe that in some hair follicles, an enzyme called 5 alpha reductase combined with testosterone produced dihydrotestosterone (DHT). This DHT is harmful to hair follices and "attacks" it, slowly breaking it down, reducing the diameter and length, so that the hair follicle becomes smaller and smaller while the color fades away. This kind of hair is known as vellous hair. Soon, this vellous hair will fall out and will not be replaced by new hair.
In men, hair that grows near the temple region, front, vertex (top) and crown (back top of head where it starts to go in a 90 degree angle toward the neck) are most susceptible to DHT. Hair on the back and sides of the head (above the ear but below te top, are the LEAST susceptible to hair loss.
One of the myths surrounding male pattern hair loss is that it is inherited trait from your mother's father. This is not true. Nor is it true that clogged pores, poor blood circulation, lack of oxygen to the follices and vitamin deficiency (only when you are dying of scurvy is this true) - cause hair loss in men. Hair follices, as does all living tissue, receives it's oxygen from the bloodstream. And if poor blood circulation where true, then not only would the hair fall out, but the scalp would start to disintegrate as well.
Besides dismissing these common myths during your investigation of male pattern hair loss, you should also come to understand the typical hair growth cycle which takes place in three stages. Hair grows from its follicle at an average rate of a 1/2 inch per month. Each hair grows for 2 to 6 years, then rests, and then falls out. A new hair soon begins growing in its place. At any one time, about 85% of the hair is growing and 15% is resting.
The psychological impact of male pattern hair loss can cause serious damage to a man's self esteem and confidence.
