I would like to think that less than optimal circulation in the scalp is a factor in the shrinking and eventual death of the hair follicles. This would make my approach to hair loss more credible. The truth is that decreased blood flow to the scalp does not cause pattern baldness. Many scientific studies have shown that the scalp has more than a sufficient supply of blood to nourish the hair follicles. Hair transplant surgery has also demonstrated this fact.

The tendency towards male pattern balding is genetic and can be inherited from either the mother or father i.e. it is not sex linked. Balding is started when dihydro testosterone molecules bond with special receptor sights on hair follicle cells. This causes the hair follicle to miniaturise and eventually to die.

Spider veins develop from tiny veins that are not important to your circulation. Varicose veins are larger veins that are part of the superficial venous system. When functioning normally, the entire system of superficial veins returns less than 10% of the blood flow from the legs. But varicose veins are not normal veins. They are diseased vessels that allow blood to move backwards. See similar questions...

Shaving your head will not, in and of itself, affect the rate of your hair's growth in any way. However, belief that shaving does affect hair growth is common. There's an article in the ShaverLog about this. See similar questions...

it develops, the hairs in the affected areas of the scalp (top of head and middle front of head) become shorter, finer and less pigmented with successive growth cycles. This androgenic alopecia seems to be associated with the presence of dihydroxytestosterone (DHT), a metabolite of testosterone. Men with a genetic deficiency of 5alpha-reductase, the enzyme that converts testosterone to DHT, do not suffer male pattern baldness. See similar questions...

This is probably a consequence of their genetic base - its affects different groups of people to different extents. Almost half of white males will experience some level of baldness by the age of 50, whereas other groups such as the Japanese and the Chinese are not affected as much. See similar questions...

In the United States where people usually get enough proteins, vitamins, and minerals, nutrition is not the culprit. Most people, of course, could improve their diet but it is doubtful if this step would halt hair loss or grow new hair. I eat a diet rich in all the nutrients, mostly from natural sources. It would be a delusion, though, to think that this is the reason why my hair is still in good shape. See similar questions...

Most scientists agree that a person's genetic makeup determines whether this person becomes bald or not. This seems straightforward if not too interesting. What is interesting is the "expression" of the genes. Expression is the degree to which a gene has an effect: for example, the rate (how fast) of baldness, the age it occurs, and the extent. Geneticists do not yet fully understand the mechanism of gene expression. See similar questions...

No. People who make such comments don't understand the oxygenation process in the transplanted grafts or the anatomy of the scalp's circulatory system. The issue is one of oxygenation, not blood supply. By their very size, large grafts over 2 mm, will result in oxygen deprivation to the hair located in their center. This has been proven over and over again by observing the phenomenon called donuting (the loss of hair follicles in the center of larger grafts). See similar questions...

Yes, but unfortunately, male pattern baldness is not a simple matter of poor circulation. If it were, hair transplants would never be successful and vibrators would be. See similar questions...

Normal hair growth can be considered as a balance between normal cyclic growth and hair loss, therefore hair loss can be considered when hair loss exceeds hair growth. Male pattern baldness begins with hair loss, and more specifically when more hair is falling than the one that is growing. This can begin from teenage years and becomes more apparent as men age. Don't think this is not common, as it affects 50% of the male population. See similar questions...

The most common cause of hair loss in men is "androgenic alopecia". genetics and hormones play a significant role specifically dihydrotestosterone (DHT). The hair in the front and top of the scalp have been "genetically programmed" to lose blood supply under the influence of a DHT at a specific time in a patient's life, at that point the hair becomes finer and eventually is completely lost.

Wearing a tight hat may abrade the hair shaft in an area where it rubs against it, but this does no harm to the follicle. The hair will grow back again with a new hat or no hat. Some people believe that the hair needs to "breathe." They believe that the continual wearing of a hat might cut off air circulation to the hair- that the hair needs an airing out once in a while. The hair follicles are not nourished by air; they are nourished by the blood supply at the base of the follicle. See similar questions...

The cause of male pattern baldness is no longer a mystery. Research has shown that when the male hormone - testosterone is exposed to 5-alpha-reductase, an enzyme in the hair follicle, it produces another hormone called dihydrotestosterone (DHT), which causes permanent hair loss. This hormone (DHT) causes the hair follicle to shrink and grow a finer hair that is lighter in color, shorter and less deeply rooted than its predecessor. See similar questions...

No, it is not. Baldness is a condition where there is loss of hair root hence no possibility of hair growth. In case of Alopecia areata there is a great chance to regain hair growth. See similar questions...
