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.
Anyone can develop alopecia; however, your chances of having alopecia areata are slightly greater if you have a relative with the condition. In addition, alopecia areata occurs more often among people who have family members with autoimmune disorders such as diabetes, lupus or thyroid disease.
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.
Alopecia areata affects people of all ages including young children. It produces circular patches of hair loss that appear overnight. More patches appear over time and eventually about 5% of people affected lose every hair on their body.
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.
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.
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.
For patients who use treatments, there are several options. However, alopecia areata cannot be "cured." As noted above, most patients experience future episodes of hair loss. Corticosteroids — Corticosteroids, commonly called steroids, are anti-inflammatory medications that are used to treat alopecia areata.
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.
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.
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.
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.
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.
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.
Topical minoxidil
Minoxidil, commonly known as Rogaine, is a topical treatment that's easy to apply and can be easily purchased over the counter. Minoxidil works to help the hair grow faster once the follicle is no longer under attack by the immune system and is capable of producing hair.
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.
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.
Telogen effluvium hair loss — the type of hair loss linked to stress — typically affects your scalp and may appear as patchy hair loss. However, it can also cause you to shed more body hair or notice less hair on your body than you normally would.
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].
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.
A deficiency in vitamin D can be linked to many different types of autoimmune disease—including alopecia areata. This study found that vitamin D deficiency was a risk factor for developing alopecia areata and that a significant number of patients with this condition had low levels of vitamin D.
