Alopecia areata is a condition where patches of hair loss develop, usually on the head. In some cases, total baldness develops. Usually the hair regrows after several months. In some cases, the hair loss is permanent.
For many people, the disease does not progress beyond patchy hair loss. However, in some cases the hair loss is extensive. A small minority of patients lose all the hair on their head (known as alopecia totalis) or all the hair on their head and body (alopecia universalis).
The condition is sometimes called androgenetic alopecia. It usually takes 15-25 years to go bald, but can be quicker. Typically, at first the hair begins to thin (recede) at the sides (temples). At the same time, the hair usually becomes thin on the top of the head.
Alopecia areata rarely causes symptoms. 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.
Sometimes, hair regrows on its own without treatment. This happens more often when someone has a few patches of alopecia areata, which have been there for less than 1 year.
Causes of Alopecia Areata
In alopecia areata, the immune system mistakenly attacks hair follicles, causing inflammation. Researchers do not fully understand what causes the immune attack on hair follicles, but they believe that both genetic and environmental (non-genetic) factors play a role.
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.
Patchy hair loss (alopecia areata)
In the type of patchy hair loss known as alopecia areata, hair loss occurs suddenly and usually starts with one or more circular bald patches that may overlap.
Is alopecia areata curable? It cannot be cured; however, it's possible to regrow hair. For some people, regrowth will happen without any help. Because alopecia areata cannot be cured, people who have regrowth can have more hair loss later.
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.
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.
Alopecia areata affects 1 in every 500 to 1,000 people in the United States. It is one of many recognized forms of alopecia; alopecia areata is the second most common form after androgenetic alopecia (male-pattern baldness in men and female-pattern baldness in women).
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.
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.
It usually begins with the hair on your head. There are three severe forms of alopecia, including: Areata (patchy hair loss on your head) Totalis (complete hair loss on your head)
Symptoms of alopecia areata
Hair loss might also occur on other parts of the face, like the eyebrows, eyelashes, and beard, as well as other parts of the body. Some people lose hair in a few places. Others lose it in multiple spots. You may first notice clumps of hair on your pillow or in the shower.
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.
Ketoconazole shampoos help treat Alopecia by cleaning the skin area around your hair follicle of sebum, or the skins natural oils that are produced. Getting rid of these oils can allow your hair follicles to receive more nutrition and release for your hair to regrow.
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.
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.
Cicatricial alopecia .
It involves inflammation that destroys hair follicles. The destroyed follicles get replaced by scar tissue, resulting in permanent hair loss in the area.
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.
Often, hair grows back within several months, even without treatment. It may grow in fine or white at first, but usually returns to its original texture and color with time. People with alopecia areata may lose and grow back their hair more than once, either in the same patches as before or in different patches.
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.
