What are the Causes of Alopecia Areata?

Last Updated on September 15, 2022 by admin


Alopecia areata is most common on the head and face, but it can affect any body part. Small, circular patches of hair fall out about the size of a quarter. In rare cases, hair loss can be much worse. There are usually no other signs or symptoms of the condition in people who have it, and they are generally in good health.

What is alopecia areata?

As a result, it can be hard to tell where the hair has fallen out. This is called alopecia areata. If these patches get together, they could look weird. It happens because the immune system attacks hair follicles, which causes hair loss to occur.

Hair loss can sometimes occur in areas of the body that do not have a lot of hair, such as the eyebrows and eyelashes and the other body regions that do have hair. It could also take a long time to grow and come back years later.

There is a chance that the condition will cause complete hair loss. Once your hair grows back, it can fall out again. Each person loses and grows hair differently. Alopecia areata can’t be cured right now. There are many options. People who have lost their hair can also get help from resources.

Types of Alopecia Areata

It can come in three different ways:

  • Alopecia areata isn’t all the same size or shape. When someone has hair loss, small patches of hair fall out on their scalp or other parts of their body. It is the most typical type of hair loss.
  • No hair at all. These people are either completely bald or have bald spots on their scalps.
  • Alopecia Universalis is a condition that affects all people, so it is called that. People who have this kind of hair loss are scarce. 

The symptoms of Alopecia Areata

Some people have alopecia areata and have changes to their nails and hair loss. People who have the condition don’t show any other signs, and most of them are healthy.

Changes in hair

One of the most common symptoms of alopecia areata is the development of small, round, or oval patches of hair loss on the scalp. In addition, any portion of the body can be affected by the illness. There are a lot of short, broken hairs or “exclamation point” hairs near the patch’s edges. These hairs are shorter at the base than they are at the tip. There’s usually no redness or scars, even on the body parts that aren’t covered. Before the hair falls out, some people say they feel tingling, burning, or itching on aspects of their body that aren’t hairy.

It is difficult to forecast what will happen next in an environment devoid of vegetation. Numerous events could occur, including the following:

  • Hair regrows in a few months after being removed. At first glance, it may appear white or gray. It may recover to its natural hue over time.
  • There are more empty places. The first patches of hair may grow back while other body parts are left without hair.
  • Patches are made by putting together small ones. alopeciaareata is a rare condition in which all of the hair on the scalp falls out, and it is tough to treat.
  • Alopecia Universalis: This is a type of disease that makes you lose all of your hair. This is a one-of-a-kind case.
  • Hair usually grows back, but there may be more hair loss down the road.
  • People who have: are more likely to have complete hair growth.

Changes to Nails

Some people, especially those who have lost a lot of hair, have changed their nails, like ridges and pits.

Alopecia Causes

Humans have an immune system that fights against hair follicles, shrinking them and slowing down new hair growth. The immune system focuses on hair follicles for some reason that hasn’t been found yet.

Alopecia areata happens even though scientists don’t know why. People who have a close family member who has the disease are more likely to get it. It is because genetics recreate a part.

People who have a family history of alopecia areata also account for other autoimmune conditions, like atopy, hyperallergic, thyroiditis, and vitiligo.

Stress doesn’t appear to be the leading alopecia cause, which isn’t what people think. The illness may be caused by stress, but the most recent research shows that it may be hereditary.

For alopecia areata: When do you need to go to the doctor for help?

Many people with alopecia areata think their hair will grow back in a year. However, for some people, the condition gets worse and lasts longer. To receive hair loss treatment, you must first consult a doctor about your situation.


In the end, alopecia areata can be a long-term or short-term issue. There’s no way to know what will happen to you because this skin condition can change. You will have a better chance of getting better if you start treatment soon. Remember that you’re not the only one. If you’re having trouble dealing with hair loss, think about joining a support group in your area.
