The most common cause of baldness in men is testosterone. This is a hormone most women's bodies do not produce.
You might say baldness is more widespread in Alaska and Anchorage because there are statistically more men living there!
Many women view baldness in men as sexy. And contrary to what many men believe, most women care more about what is in a man's head than what is on it. A man's personality, honesty, loyalty, etc. mean much more to women than a full head of hair on a man does.
It is related to testosterone levels.
growth hormones and the fact that women age slower than men
The term dominant is a misnomer here as the trait is not dominant or the number of women with the trait would be much higher. Pattern baldness is a sex-linked trait. Male pattern baldness alleles are present on the X chromosome which means that only one copy of the allele is required for a male to exhibit the trait (the y chromosome, being much smaller, doesn't have the gene locus for this trait). Females must have 2 alleles for the characteristic in order to exhibit the the trait.
Genetics and testosterone levels are correlated with male pattern baldness.
Androgenic alopetia (Male Pattern Baldness) is caused by a genetic sensitivity (of hair follacles) to DHT (dihydrotestosterone, I think), an androgen that controlls sex drive and hair reproduction and is rampant/necessary at birth and puberty, this sensitivity cause follicles to shink, preventing proper growth of hair, and shortening the overall lifespan of said follicles.
The medical term for baldness is alopecia. Baldness is hair loss or absence of hair, and it can happen anywhere on the body where hair grows. There are many types of baldness, each with a different cause, and it can be localized to the front and top of the head, patchy, or involve the entire head. Male-pattern baldness is the most common form of alopecia, and it affects around 50% of men by the time they reach the age of 50. It is hereditary and thought to be associated with having an excess of a certain hormone, which has an effect on hair follicles.
Dr. Gu Yuanfei, director of hair transplantation, said: general baldness is male hormone alopecia, and this type of hair loss is more serious in men than in women, and the form is not the same. Androgenetic alopecia is the most common type of hair loss, accounting for more than 95 percent of hair loss. Male androgen hair loss is the performance of the hairline, gradually spread to the top of the head, serious is baldness. The performance of female male hormone alopecia is the overall thinning of the hair on the top of the head, and increasingly sparse, and even visible scalp. However, women do not go bald and still have hair.
Obviously, baldness can be caused by physical removal of the hair by shaving and in stress disorders or with severe anxiety, it can be being pulled out by the individuals with an emotional condition (sometimes called trichotillomania). The most common benign form of baldness is male pattern baldness that is an inherited condition from either side of the family. It is also possible for some women to have hereditary baldness, although the patterns differ from male pattern baldness. Baldness can be an infrequent side effect of malnutrition, is present in radiation treatment or poisoning, and with chemotherapy or accidental exposure to some other chemicals that cause poisoning. Additional causes are fungal diseases; thyroid disorders; braids and ponytails pulled too tight too often; physiological "shocks to the system" like major surgery, pregnancy, high fever, and crash diets. Other more rare and infrequent conditions can also result in baldness of the head as well as hair on all parts of the body, such as alopecia areata. The exact cause is unknown, but it is likely an inherited genetic disorder that may be associated with autoimmune disease that causes the body to attack its own hair follicles.
It is more common in men.
