In alopecia areata, the body's immune system mistakenly attacks the hair follicles for reasons that are not clear. Fortunately, the follicles retain their ability to regrow hair, and the hair loss is not permanent in most cases.
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.
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.
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.
Alopecia areata tends to appear during childhood, but it could surface at any age. It can also disappear for decades, Freidman says. "It's common to have it as a kid, have it go away, and then have it come back 20 years later," he says.
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).
The condition can develop at any age, although most people develop alopecia areata for the first time before the age of 30.
There is no cure for alopecia areata. If you have a few, small patches of hair loss on your head, it's likely your hair will grow back within a few months. Your doctor may not prescribe treatment in those cases. For larger areas of hair loss, your doctor may prescribe steroid injections under your scalp.
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. When hair fails to grow back, treatment can help. Self-care also plays an important role in the lives of people who have alopecia areata.
Baldness is hair loss, or absence of hair. It's also called alopecia. Baldness is usually most noticeable on the scalp, but can happen anywhere on the body where hair grows. The condition is more common in men than in women.
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.
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.
The Ludwig scale defines three broad stages of hair loss. In stage 1, the hair on the top of the head begins thinning. In stage 2, the scalp starts to become visible. In stage 3, all of the hair at the crown may be lost, resulting in baldness.
Scarring (cicatricial) alopecia
Scarring alopecias are typically caused by inflammation that results in destruction of the hair follicle leading to irreversible hair loss.
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.
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 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.
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.
Alopecia areata (AA) occurs when the immune system attacks the hair follicle. Studies have shown a relationship between AA and low vitamin D levels. Vitamin D should be supplemented if levels are low.
Prescription-strength corticosteroids in liquid form can be applied directly to the scalp. This is often an effective treatment for children affected by alopecia areata. Corticosteroid injections into areas of patchy hair loss on the scalp may help revive hair growth within several weeks in people with alopecia areata.
A few people who develop alopecia areata will progress to total scalp baldness (alopecia totalis). Even fewer people will lose all scalp and body hair (alopecia universalis).
Alopecia areata isn't usually a serious medical condition, but it can cause a lot of anxiety and sadness. Support groups are out there to help you deal with the psychological effects of the condition. If you lose all your hair, it could grow back.
Jada Pinkett Smith is one of the most famous celebrities with alopecia. She was diagnosed with alopecia areata in 2018, and has been open about it on social media since then. Jada has used steroid treatment and covered her hair with wigs and headscarves to disguise her condition.
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.
