Alopecia Areata – So called Puzhuvettu in Tamil

Alopecia Areata (AA):


Alopecia is the medical term for baldness.

Alopecia areata is a type of hair loss that occurs when the human immune system will falsely identify the hair matrix as a foreign body and destroys it, leading to patchy hair loss in the region of attack. The damage to the follicle is usually not permanent. It is an autoimmune disease; that is, the person’s immune system attacks their own body. In this case, their hair follicles. T cell lymphocytes cluster around affected follicles, causing inflammation and subsequent hair loss. The extent of the hair loss varies; in some, it is only in a few spots and in others, the hair loss can be greater.


It is believed that the person’s genetic make up may trigger the autoimmune reaction of alopecia areata, along with other unknown triggers.

What happens in alopecia areata?

Alopecia areata usually begins when clumps of hair fall out, resulting in totally smooth, round hairless patches on the scalp. In some cases the hair may become thinner without noticeable patches of baldness, or it may grow and break off, leaving short stubs (called “exclamation point” hair). In rare cases, complete loss of scalp hair and body hair occurs. The hair loss often comes and goes—hair will grow back over several months in one area but will fall out in another area.

Symptoms of AA:

Typical first symptoms of AA are small bald patches. The underlying skin is unscarred and looks superficially normal. These patches can take many shapes, but are most usually round or oval. AA most often affects the scalp and beard, but may occur on any hair-bearing part of the body.7d1f1d71-84a9-4a9d-9b29-55444cd77d85 alopecia-areata_691950574e5e8c1c6a22b


Commonly, alopecia areata involves hair loss in one or more round spots on the scalp.

  • Hair may also be lost more diffusely over the whole scalp, in which case the condition is called diffuse alopecia areata.
  • Alopecia areata monolocularis describes baldness in only one spot. It may occur anywhere on the head.
  • Alopecia areata multilocularis refers to multiple areas of hair loss.
  • Ophiasis refers to hair loss in the shape of a wave at the circumference of the head.
  • The disease may be limited only to the beard, in which case it is called alopecia areata barbaealopecia_areata1_beard
  • If the patient loses all the hair on the scalp, the disease is then called alopecia totalis.
  • If all body hair, including pubic hair, is lost, the diagnosis then becomes alopecia universalis.

Alopecia areata totalis and universalis are rare.



How is alopecia areata diagnosed?

Alopecia areata is diagnosed through a medical history and physical examination. The doctor will ask questions about the hair loss, look at the pattern of hair loss, and examine the scalp. And he or she may tug gently on a few hairs or pull some out.

If the reason for your hair loss is not clear, the doctor may do tests to check for a disease that could be causing the hair loss. Tests include:

  • Hair analysis. Your doctor will take a sample of your hair and examine it under a microscope. A scalp sample is also sometimes taken.
  • Blood tests, including testing for a specific condition, such as an overactive or underactive thyroid gland (hyperthyroidism or hypothyroidism).

Prone to Alopecia Areata?

Anyone can develop alopecia areata; however, chances of having alopecia areata are slightly greater if you have family history with the disease. In addition, alopecia areata occurs more often among people who have family members with other autoimmune disorders such as diabetes, lupus, or thyroid disease.

How stress triggers Alopecia Areata???


Tips for Alopecia Areata:

Cosmetic and protective techniques that people with alopecia areata can try include:

  • Using makeup to hide or minimize hair loss
  • Wearing coverings (wigs, hats, or scarves) to protect the head from the elements
  • Reducing stress. Many people with new-onset alopecia areata have had recent stresses in life, such as work, family, deaths, surgeries, accidents, etc. However, this has not been proven scientifically as a cause of alopecia areata.

Alopecia areata does not affect you as another condition might: it is not painful, it does not make you feel sick, and it does not result in serious health problems. You cannot spread it to other people, and it should not interfere with school, work, or recreation.

But if hair loss is making to feel unattractive, it is important to talk to someone about it.

Alopecia areata cannot be totally cured; however, it can be treated and hair can grow back. While the disease is not medically serious, it can impact people psychologically. Support groups are available to help people with alopecia areata deal with the psychological effects of the condition.

Alopecia can certainly be the cause of psychological stress. Because hair loss can lead to significant appearance changes, individuals may experience social phobia, anxiety, and depression.
