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.
Men inherit the baldness gene from the X chromosome that they get from their mother. Female baldness is genetically inherited from either the mother's or father's side of the family. Baldness may be influenced by a number of other factors as well, including age, health, diet, hormones, seasonal changes and climate.
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.
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 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.
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.
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.
Baldness is hereditary
So while you may well share some of your father's DNA as well as your grandfathers' on both sides - as well as DNA from the female sides of your family - it doesn't necessarily mean that you will inherit the gene - or set of genes - involved in genetic hair loss.
Skipping a Generation: Myth or Fact
There is no scientific basis for the idea that baldness skip generations, regardless of any old wives tales you may have heard from the grapevine.
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. For example, researchers can now grow hair follicles in a lab.
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.
Patients generally underestimate the degree of balding in the family. They may not mean to, but they often do. A patient who says “nobody in my family has balding” may be correct. I would estimate that 30 % -50 % of the time they are correct but 30 % -50 % of the time they are not.
Age: The chances of developing male pattern baldness increase with age. About 25% of people assigned male at birth see the first signs of hair loss before age 21. By age 50, half experience hair loss, and about 70% will lose hair as they get older. Hormones: Dihydrotestosterone (DHT) is a type of androgen.
Most bald men shave their heads about once a week. The best time to exfoliate your scalp is before shaving. This will soften the skin and hair to allow for a closer, more even shaving experience.
The youngest documented case of male pattern baldness (that we currently know of) occurred in a fifteen-year-old teenage boy. Despite the fact that he was healthy in every other way, the child began noticing hair loss across his hairline.
Only riboflavin, biotin, folate, and vitamin B12 deficiencies have been associated with hair loss.
Unlike nuclear DNA, which comes from both parents, mitochondrial DNA comes only from the mother.
Hereditary hair loss cannot be prevented, but there are medical treatments that can maintain, improve, and optimize hair growth, such as minoxidil, finasteride, and spironolactone. Topical minoxidil is FDA-approved for hair loss in men and women.
Baldness often begins in the hairline. The flat or mildly receded hairline you previously had has transformed into a distinctly M-shaped one. For most people, this begins with hair thinning at the crown of the head and temples and often starts with thinning hair, rather than total hair loss.
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.
Most people feel as though they look more like their biological mom or biological dad. They may even think they act more like one than the other. And while it is true that you get half of your genes from each parent, the genes from your father are more dominant, especially when it comes to your health.
Males normally have an X and a Y chromosome (XY). A male inherits an X chromosome from his mother and a Y chromosome from his father. The picture above therefore shows the chromosomes of a male as the last pair of chromosomes (XY). Sometimes, there is a change in one copy of a gene which stops it from working properly.
