Alopecia areata typically begins with sudden loss of round or oval patches of hair on the scalp, but any part of the body may be affected, such as the beard area in men, or the eyebrows or eyelashes.
Sudden Loss of Patches of Hair
Bald spots may grow very slowly in one area or you may notice a patch or strip of hair loss that appears within just a day or two. In some cases, you may notice burning or stinging before sudden hair loss.
Hair loss, also called alopecia, is a disorder caused by an interruption in the body's cycle of hair production. Hair loss can occur anywhere on the body, but most commonly affects the scalp.
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.
The hair loss associated with alopecia areata is unpredictable, and as far as doctors and researchers can tell, it appears to be spontaneous . The hair may grow back at any time and then may fall out again. The extent of hair loss and regrowth varies greatly from person to person.
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.
This type of baldness is not usually caused by a disease. It is related to aging, heredity, and changes in the hormone testosterone. Inherited, or pattern baldness, affects many more men than women. Male pattern baldness can occur at any time after puberty.
Alopecia areata frequently presents as the sudden onset of smooth, round, hairless patches on the scalp. The affected areas are usually skin-colored but may have a peach color. Occasionally, there are scattered short colored or white hairs within the hairless patch.
For some, it may take as short as 8 weeks to see improvement with treatment. For others, the same treatment may not work. It is said that most cases of alopecia areata last for a few months to a year, following which normal hair growth resumes. However, there may be cases of permanent hair loss as well.
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.
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.
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.
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.
Telogen effluvium from nutritional, hormonal, and drug etiologies can lead to large clumps of hair loss in a similar fashion to alopecia areata. The loss is diffuse, not localized. Tinea capitis has hair loss accompanied by scale and inflammation. Secondary syphilis can result in diffuse patchy alopecia.
Everyone is born with hundreds of thousands of hair on the head. The hair cycle consists of three phases: the growth phase, which is called anagen, the resting phase, which is called catagen, and the shedding phase, which is the telogen phase.
If your daily hair fall is more than the usual 80-100 strands of hair, you might be suffering from stress-related hair loss. If you notice bald patches on your scalp, it may be a sign of Alopecia Areata. If you have had the urge to pull out your hair, it may be stress-induced Trichotillomania.
Can Alopecia Be Reversed? Whether your hair loss is caused by hormones or an autoimmune disorder, regrowing your hair by using new medications and modifying your diet can be possible as long as you start treatment early.
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.
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.
Alopecia areata (AA) is an autoimmune disorder leading to non-scarring hair loss. As long as hair follicles are not destroyed, the potential for hair regrowth remains. Alopecia universalis is a severe form of AA and the chance of full hair regrowth is below 10%.
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.
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.
