WHAT IS ALOPECIA?

What is Alopecia Areata?

Alopecia areata is a type of hair loss that occurs when your immune system mistakenly attacks hair follicles, which is where hair growth begins. The damage to the follicle is usually not permanent. Experts do not know why the immune system attacks the follicles. Alopecia areata is most common in people younger than 20, but children and adults of any age may be affected. Women and men are affected equally.

What you need to know about Alopecia Areata…

Alopecia areata is a common autoimmune skin disease, causing hair loss on the scalp, face and sometimes on other areas of the body. In fact, it affects as many as 6.8 million people in the U.S. with a lifetime risk of 2.1%.

People of all ages, both sexes and all ethnic groups can develop alopecia areata. It often first appears during childhood and can be different for everyone who has it.

What causes Alopecia Areata?

There are lots of factors that contribute to developing this complex condition. Alopecia areata is an autoimmune disease, which means your immune system mistakes the normal cells in your body as foreign invaders and attacks these cells.

Scientists aren’t exactly sure what “triggers” the immune system to attack healthy hair follicles when people have alopecia areata, or even if these triggers first happen inside the body (from a virus or bacteria), outside the body (from something in your surroundings) or if it’s a combination of both.

Are there different types of Alopecia Areata?

With all forms of alopecia areata, your body’s own immune system attacks your healthy hair follicles, causing them to become much smaller and drastically slow down production to the point that hair growth may stop.

Depending on which type and severity of the disease you have, you might experience hair loss in different areas and your hair loss and regrowth may be unpredictable and cyclical (happen over and over) for many years. Though for some people, hair may also regrow in a few months.

Three of the more well-known types of alopecia areata:

  • Alopecia areata patchy — The most common form, with one or more coin-sized hairless patches on the scalp or other areas of the body.
  • Alopecia totalis — Total loss of the hair on the scalp.
  • Alopecia universalis — Complete loss of hair on the scalp, face and body.

Currently, there is no cure for alopecia areata. But the good news is that even when your disease is “active,” your hair follicles remain alive. This means that your hair can grow back again — even after a long period of time and even if you have more than 50% hair loss.

What kinds of symptoms will I have with Alopecia Areata?

All types of alopecia areata result in some form of hair loss. There is no way to predict the pattern of hair loss and regrowth you will experience or how severe or long lasting it will be. It’s important to remember that alopecia areata is different for everyone who has it.

Still, there are some common symptoms of alopecia areata that are good to know and recognize. However, the only way to be sure you have alopecia areata is to make an appointment and get a diagnosis from a doctor.

Symptoms of alopecia areata may include:

  • Small, round (or oval) patches of hair loss on the scalp, beard area of the face or other areas of the body with hair
  • Hair loss and regrowth at the same time in different areas of the body
  • Significant hair loss in a very short period of time
  • Hair loss that’s mostly on one side of the scalp, instead of both sides
  • “Exclamation point” hairs that are narrow at the base/next to the scalp
  • “Stippling” or “Pitting” (rows of tiny dents) on the fingernails

What are my options for treatment and care of affected areas?

Unlike many skin diseases, alopecia areata does not cause rashes, redness, hives or severe itching. Even so, some people with alopecia areata find it helpful to protect exposed skin — the head, ears and face — from damaging sun exposure or other harsh elements. A scalp without hair is more sensitive to cold as well.

Depending on which type of alopecia areata you or your child has, your age, and the extent of hair loss, there are a variety of treatment options available for disrupting or distracting the immune attack and/or stimulating the hair follicle — especially for those who have milder forms of the disease (less than 50% hair loss).

For those who have more than 50% hair loss on their scalp or other areas of the body, there are oral and injectable medications available. However, these medications do not work for everyone. That’s why it’s important to talk with your doctor to discuss the risks and benefits of using any medications.

Did you Know?

Alopecia areata is known as a “polygenic disease.” This means that, unlike a single-gene disease, both parents must contribute a number of specific genes in order for a child to develop it. Because of this, most parents will not pass alopecia areata along to their children. With identical twins — who share all of the same genes — there’s only a 55% chance that if one has alopecia areata, the other will, too. This is why scientists believe that it takes more than just genetics to cause the disease and that other environmental factors also contribute to people developing alopecia areata.
