People with the disease are usually healthy and have no other symptoms. Alopecia areata typically begins with sudden loss of round or oval patches of hair on the scalp, but any part of the body may be affected, such as the beard area in men, or the eyebrows or eyelashes.
Hair loss (alopecia) can affect just your scalp or your entire body, and it can be temporary or permanent. It can be the result of heredity, hormonal changes, medical conditions or a normal part of aging. Anyone can lose hair on their head, but it's more common in men.
Alopecia areata is sometimes triggered by viral infections such as influenza that causes excess production of interferons (IFN). IFN-γ is one of the key factors that lead to the collapse of immune privilege.
“Alopecia Areata itself does not compromise the immune system or cause immune deficiency and there is no reason to think that people with Alopecia Areata are more at risk from COVID-19 than the general population, either in terms of catching the virus or being more severely affected by it.
Alopecia areata is an autoimmune disease. This means that your immune system mistakenly attacks a part of your body. When you have alopecia areata, cells in your immune system surround and attack your hair follicles (the part of your body that makes hair).
The disease is associated with increased risk of other autoimmune disorders (Table 2). Approximately, 12-16% of individuals with alopecia areata develop an autoimmune disease [29, 30].
Alopecia areata is a common autoimmune disease leading to non-scarring hair loss [1]. In the last year, there have been reported numerous cutaneous manifestations due to coronavirus disease 2019 (COVID-19), among these acute telogen effluvium [2] and alopecia areata can be encountered [3,4,5].
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.
Although, so far there is no evidence to suggest those with alopecia areata are at a higher risk of contracting the virus, if you are on medication that affects your immune system, you may want to be particularly cautious because of the potential for greater risk of complications if infected.
Alopecia areata is more common among African Americans but less common among Asians, compared with whites, according to a new study involving registry data for more than 11,000 individuals.
In most people, new hair eventually grows back in the affected areas, although this process can take months. Approximately 50 percent of people with mild alopecia areata recover within a year; however, most people will experience more than one episode during their lifetime.
There is no cure for AA. While treatments may promote hair growth, new patches of hair loss may continue to appear. The treatments are not a cure. Only the body, itself, can eventually turn off the condition.
On the AIP elimination diet, you will avoid grains, legumes, nightshades (such as potatoes and peppers), dairy, eggs, coffee, alcohol, sugar, oil and food additives. After a few months, you can work the excluded foods back in one at a time to figure out which foods trigger an inflammatory reaction.
Most people see noticeable hair shedding two to three months after having a fever or illness. Handfuls of hair can come out when you shower or brush your hair. This hair shedding can last for six to nine months before it stops. Most people then see their hair start to look normal again and stop shedding.
Ways to Stop Alopecia Areata from Spreading or Worsening
Avoiding unnecessary hair or scalp trauma, reducing stress and analyzing your diet are all worthwhile endeavors when attempting to prevent alopecia areata from spreading.
Alopecia occurs for many different reasons and presents in various ways. It can occur suddenly or develop gradually over time. Sudden-onset causes include illness, diet, medications, and childbirth. Alopecia that has a gradual onset more likely has a genetic component.
Androgenic alopecia (AGA) is associated with significant cardiovascular risk factors that also have a negative impact on brain aging.
Compared with the general population, increased prevalence rates of psychiatric disorders are associated with alopecia (Koo et al., 1994) suggesting that people with alopecia may be at higher risk for development of a major depressive episode, anxiety disorder, social phobia or paranoid disorder.
Some types of alopecia can't be cured. However, most kinds can be controlled with medical treatments to prevent worsening and, sometimes, hair can be regrown. Treatment success also varies vastly depending on the cause.
Both men and women tend to lose hair thickness and amount as they age. This type of baldness is not usually caused by a disease. It is related to aging, heredity, and changes in the hormone testosterone. Inherited, or pattern baldness, affects many more men than women.
Studies show that people with alopecia areata can have other autoimmune diseases, such as thyroid disease. However, the fact that you have alopecia areata doesn't mean you will automatically develop another autoimmune disease.
Bright colored fruits and vegetables contain antioxidants that help reduce inflammation. These include apples, strawberries, blueberries, raspberries, pineapple, cherries, broccoli, cauliflower, spinach and green cabbage. And with these, symptoms of alopecia areata might also improve. This contains many antioxidants.
