The X or female chromosome carries the primary baldness gene, and men inherit this X chromosome from their mothers. This makes the hereditary factor around baldness most dominant on your mother's side.
However, much of your phenotype is determined by the genetic instructions, or genotypes, you inherited from both sides of your family. Although your hair characteristics may seem to physically favor one side over the other, you get the same amount of genetic information from both parents.
By the time you turn 30, you have a 25% chance of displaying some balding. By age 50, 50% of men have at least some noticeable hair loss. By age 60, about two-thirds are either bald or have a balding pattern. While hair loss is more common as you get older, it doesn't necessarily make it any easier to accept.
There are several other causes of hair lossincluding medical illnesses like thyroid, or diabetes; stress, certain medications can cause it too like anti-coagulants, blood thinners, etc, nutritional deficiencies, hormonal imbalance, crash dieting, and oral contraceptives.
One popular myth is that hair loss in men is passed down from the mother's side of the family while hair loss in women is passed down from the father's side; however, the truth is that the genes for hair loss and hair loss itself are actually passed down from both sides of the family.
The X or female chromosome carries the primary baldness gene, and men inherit this X chromosome from their mothers. This makes the hereditary factor around baldness most dominant on your mother's side.
Male pattern baldness tends to be hereditary and runs in families. Sometimes men go against family traits and lose hair even if their male relatives don't. This may be due to the baldness gene skipping a generation or lifestyle choices switching the gene on.
On average it takes 15-25 years for men to go completely bald. This process can begin at any age. About two thirds of men are either bald or have a balding pattern by the age of 60. In a nutshell, there is no particular age when you can expect to see hair loss.
Many of the genes responsible for baldness and hair loss tend to come from your maternal grandfather, even though genes from both of your parents and all of your grandparents can also play a role. If your maternal grandfather is bald or is losing their hair, you are a likely candidate for hair loss problems yourself.
There are racial differences, however, in the incidence of male pattern baldness. The highest rates are found among Caucasians, followed by Afro-Caribbeans. Chinese and Japanese men have the lowest rates.
So, for the questions “Do women like bald men?” the overwhelming majority of women gave positive answers. 87.5% of women of different ages and nationalities surveyed find bald men attractive compared to only 12.5% of women, who gave negative answer.
Japan, Korea and the Rest of East Asia
East Asians are furthest from the Mediterranean region and also have the lowest rate of baldness which does not seem to be an accident. Incidentally, their baldness rate can range from 20% to the low 30s, which is still a significant portion of the population.
Physical features. Physical features such as hair color, hair texture, hairline, skin, and varicose veins are inherited from your mother.
The general consensus seems to be that parting on one's left makes a person look competent and masculine, whereas parting on the right makes a person look warm and feminine.
About 70% of men will lose hair as they get older. And 25% of bald men see first signs of hair loss before age 21. “Recent advances offer a lot of hope in both treating and preventing different types of baldness,” says dermatologist Amy Kassouf, MD.
Certain races have higher rates of hair loss compared to others. Caucasians have the highest rates out of all the ethnic groups. On the opposite end of the spectrum, Native American Indians, Inuits, and Chinese have the lowest rates.
Male pattern baldness is related to your genes and male sex hormones. It usually follows a pattern of receding hairline and hair thinning on the crown. Each strand of hair sits in a tiny hole (cavity) in the skin called a follicle.
Baldness can of course skip generations! If you have bald relatives on both sides of your family tree the chances are high you will be too. However, if the baldness shows up only on one side, it's highly possible the MPB gene will skip not only you but also your siblings.
“It's a combination of androgens, which is DHT, and genetics, which you get from both your mother and your father,” said Dr. Ivan Cohen, an associate clinical professor of dermatology at Yale University School of Medicine. Like other genetic traits, hair loss can strike one brother in a family and not the other.
You might be tempted to blame your pillowcase if you're noticing hairs on your pillow in the morning. But, there is no evidence that pillowcases cause or contribute to hair loss.
Unfortunately, male and female pattern baldness is not reversible without surgical intervention. However, if detected early enough, certain medications, such as minoxidil, finasteride, and Dutasteride can help halt the progression of thinning hair.
Is Hair Color Inherited from Mother or Father? Hair color comes from both parents through the chromosomes passed onto their child. The 46 chromosomes (23 from each parent) have genes made up of DNA with instructions of what traits a child will inherit.
All men inherit a Y chromosome from their father, which means all traits that are only found on the Y chromosome come from dad, not mom. The Supporting Evidence: Y-linked traits follow a clear paternal lineage.
