Alopecia areata is an autoimmune disease that causes hair loss in both children and adults. It often begins with a few bald spots on the scalp before it spreads to other hair follicles.
The extent of alopecia (how much hair has fallen out) varies and links to the different subtypes. Some said their hair loss involved one small patch about the size of a 1p coin which regrew after a few weeks or months. Others developed more patches which sometimes joined up into bigger bald areas over time.
Signs & Symptoms
New patches may spread by joining existing bald patches. These larger bald areas can appear while hair is regrowing in older hairless patches. Loss of hair can be permanent in some cases. Hair follicles may deteriorate, but oil producing glands in the skin (sebaceous glands) usually change very little.
In rare cases, hair is eventually lost from the entire scalp, called alopecia totalis. There is a progression to complete loss of body hair, a type of the disease called alopecia universalis. This is rare.
It may be progressive, meaning it gets worse over time, or it may not. For some people, small bare patches join together and turn into large patches. You're more likely to have extensive alopecia areata if: You have eczema.
Is alopecia contagious? Alopecia is not contagious. Individuals who develop alopecia areata typically have both a family history and some type of environmental trigger, such as emotional or physical stress.
Overview: Alopecia areata is a non-contagious autoimmune disease that occurs at any age. Its degree varies from one person to another. The disease causes hair loss on the scalp and other places on the body.
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.
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.
How Long does Hair Loss Last? In half of patients with alopecia areata, individual episodes of hair loss last less than one year, and hair grows back without treatment. These patients may experience recurrent episodes of hair loss that spontaneously regrow or respond quickly to treatments.
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.
The term end stage scarring alopecia is often tacked onto the report when the pathologist sees lots of scarring and little in the way of inflammation. To the pathologist, the finding of ESSA implies that hairs in the biopsy have been destroyed and there is not much left anymore to destroy.
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.
If you are experiencing thinning or balding, our Bosley experts recommend washing no more than three times a week.
When does alopecia areata begin? You can get alopecia areata at any age; however, most people develop it by 30 years of age. For many, the disease begins during childhood or the teenage years.
The only sign of alopecia areata is often sudden hair loss. The patches of hair loss can grow larger. Sometimes, the patches grow larger and become one large bald spot.

Thinning Eyebrows, Eyelashes, or Beard
While hair loss on the scalp is the most common, people can also lose hair all over the body. According to the National Alopecia Areata Foundation, this type of condition can cause patches of hair loss from the eyebrows, eyelashes, beard, nose hairs, or pubic hairs.
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.
Hair often looks noticeably different on the edges of bald patches caused by alopecia. These small hairs bordering the hairless spots are referred to as exclamation mark hairs since the hairs taper, thinning as they go down and looking like a classic exclamation mark.
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.
Alopecia Areata
Hair from the scalp typically falls out in small patches and is not painful. Hair in other parts of the body, including the eyebrows and eyelashes, may also fall out. Over time, this disease may lead to alopecia totalis, or complete hair loss.

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.
