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.
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.
It is believed that the person's genetic makeup may trigger the autoimmune reaction of alopecia areata, along with a virus or a substance the person comes into contact with. Alopecia areata is an unpredictable disease. In some people, hair grows back but falls out again later. In others, hair grows back and remains.
The condition can develop at any age, although most people develop alopecia areata for the first time before the age of 30. Alopecia areata is not life-threatening and does not cause physical pain. However, the psychosocial effects of hair loss can be devastating.
Frontal fibrosing alopecia
It can come on suddenly or gradually and affect just your scalp or your whole body. Signs and symptoms of hair loss may include: Gradual thinning on top of head. This is the most common type of hair loss, affecting people as they age.
The first sign of alopecia areata is often a round or oval bald patch on the scalp.
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.
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.
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.
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.
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.
Prolonged periods of stress can result in telogen effluvium. Hair loss typically occurs about 3 months after the stressful event.
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.
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.
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.
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.
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.
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 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].
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 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.
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.
One of the early symptoms of alopecia could be changes to your nail beds. If you notice pitting, small craters, or white patches on your nails, this could be a warning sign.
