The inheritance pattern of alopecia areata is unclear because multiple genetic and environmental factors appear to be involved. Overall, the risk of developing the condition is greater for first-degree relatives (such as siblings or children) of affected individuals than it is in the general population.
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.
Is alopecia areata hereditary? Yes, heredity plays a role. Alopecia areata is a “polygenic disease” which requires the contribution of many genes to bring about the disease, as well as a contribution from the environment.
Male or female hereditary hair loss is caused by genetic or hormonal influences. It is also called androgenic alopecia because it is affected by the hormones called androgens. These are present in both men and women, but in different quantities.
Asthma, hay fever, atopic dermatitis, thyroid disease, vitiligo, or Down syndrome: Research shows that people who have one of these diseases are more likely to get alopecia areata.
1) Yes, alopecia areata can pass from parents to children - but it is not common. About 6 % of your son's children would be predicated to have alopecia areata and 94 % would not. In other words, it' s possible for your son to have a child with alopecia areata but most likely he will not.
Alopecia areata is also a genetic disease and usually first appears during childhood. The good news is that when someone has alopecia areata, their hair can grow back even after it has fallen out. So while hair loss from alopecia areata cannot be prevented, it can be treated.
There is no known predictor of how many AA genes you inherit, their persistence and how strong the genetic influence is in you. Alopecia areata often skips generations with no predictability.
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.
“The best advice is to eat a healthy and balanced diet, rich in protein and [with] many vegetables.” Sobel also says that fresh herbs such as parsley and basil can lower the risk or slow the onset of male pattern baldness, otherwise known as androgenic alopecia.
Calcipotriol, a vitamin D analog, has been reported to be topically used in treating alopecia areata with promising results. Combination therapy of vitamin D analogs with corticosteroids might also be used in treating alopecia areata.
The disease usually occurs in young adults, and its incidence peaks between 20 and 25 years of age2. The first disease episode typically presents before 20 years of age2. One study reports that 85.5% of Asian patients with AA present before 40 years of age4.
Alopecia areata (AA) is a common, non-scarring, autoimmune hair-loss disorder with a complex genetic and environmental etiology. A higher incidence rate of AA in the female population is well described.
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.
Unlike nuclear DNA, which comes from both parents, mitochondrial DNA comes only from the mother.
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.
There is currently no cure for alopecia areata, although there are some forms of treatment that can be suggested by doctors to help hair re-grow more quickly. The most common form of alopecia areata treatment is the use of corticosteroids, powerful anti-inflammatory drugs that can suppress the immune system.
Genetics
In women, hereditary hair loss usually starts after the age of 40. Roughly 40% of women have noticeable hair loss by the age of 50. And less than half of women get through life with a full head of hair. Hereditary hair loss looks a little different in women than it does in men.
Can Alopecia Be Reversed? Whether your hair loss is caused by hormones or an autoimmune disorder, regrowing your hair by using new medications and modifying your diet can be possible as long as you start treatment early.
Alopecia areata can occur at any age but about half of cases come on in childhood and 80% of cases come on before the age of 40 years. Men and women are equally affected. The condition tends to be milder if it comes on at an older age.
A variety of factors are thought to cause alopecia areata (al-o-PEE-she-uh ar-e-A-tuh), possibly including severe stress. With alopecia areata, the body's immune system attacks the hair follicles — causing hair loss.
The condition can develop at any age, although most people develop alopecia areata for the first time before the age of 30. Alopecia areata is not life-threatening and does not cause physical pain. However, the psychosocial effects of hair loss can be devastating.
Most people know alopecia to be a form of hair loss. However, what they don't always know is that there are three main types of the condition – alopecia areata, alopecia totalis and alopecia universalis.
Female-pattern baldness is a pattern of hair loss (alopecia) caused by hormones, aging and genetics. Unlike male-pattern baldness, female-pattern baldness is an over-all thinning which maintains the normal hairline.
Currently, there is no cure for alopecia areata. But the good news is that even when your disease is “active,” your hair follicles remain alive. This means that your hair can grow back again — even after a long period of time and even if you have more than 50% hair loss.
