Alopecia Areata


Alopecia areata can develop suddenly over a few days or weeks. It can lead to unexplained hair loss, often in patches the sizes of coins. Today, around 6.8 million people suffer from alopecia areata in the United States. In addition, around half of them are males and white. So, what exactly is alopecia areata, and what causes it? Is there any treatment for the resulting hair loss?

Let’s explore more.

What is Alopecia Acreata?

This is an autoimmune disorder that causes people to lose hair. Sometimes, it’s just a few spots, but the disease might lead to total hair loss as well. At times, hair does grow back. You may experience hair loss on your head or over your entire body. You may also experience hair thinning.

What Causes Alopecia Areata?

Alopecia areata forces your white blood cells to fight against the cells in your hair follicles.

As a result, the follicles suffer shrinkage and produce less hair. This leads to sudden hair loss that might extend for weeks.

Scientists aren’t sure what causes the white blood cells to attack the hair follicles. However, most patients have a family member who went through the same condition.

Therefore, genetics may have a part to play in the development of alopecia areata. Additionally, the disorder is related to vitiligo, where the skin loses its pigments in patches.

Usually, the condition affects people whose average age is 43.

Types of Alopecia Areata

Patients may develop alopecia areata that starts with hair loss. The hair loss may not always remain limited to the head and spread to other body parts.

As a result, patients may have the following types of alopecia areata:

  • Alopecia areata: Alopecia means bald, and areata refers to patchy. You may lose hair from scalps, armpits, beards, and eyebrows.
  • Alopecia totalis: The whole scalp loses hair and turns bald when you have alopecia totalis.
  • Alopecia universalis: This is a rare condition where the whole body loses its hair.

Treatment of Alopecia Areata

Doctors don’t have a cure for alopecia areata at this moment. However, people who lose only a few patches of hair generally get better without any treatment.

For others, physicians may prescribe corticosteroids to inhibit the immune system. Patients may need to take them orally, through injections, or apply them as ointments.

In addition, doctors may recommend other medicines to encourage new hair growth like:

  • DPCP
  • Anthralin
  • Minoxidil

Moreover, UVA phototherapy is coming up as a non-invasive way to provide an alternative treatment.

Currently, natural remedies don’t seem to work for alopecia areata. However, some people try remedies at home that include rubbing different things on the scalp like:

  • Onion and onion juice
  • Coconut milk
  • Garlic juice

However, none of them are proven by science to work.

Additional Precautions

Patients may need to follow a few precautions if they lose hair due to alopecia areata. They include:

  • Protecting exposed patches of scalp or skin with sunscreen
  • Using a cap or hat to protect the scalp
  • Wearing glasses to prevent debris falling into the eye due to missing eyebrows and eyelashes

Symptoms of Alopecia Areata

Hair loss is a prominent symptom of alopecia areata. Patients may start to lose hair in sizes or a quarter that may progress to other areas.

Additionally, they may lose hair from eyelashes, beards, and other body parts.

Moreover, the nails of fingers and toes can also be affected. Also, they may be affected first before the hair loss starts.

Nails may lose shine, turn brittle, or become rough. You may also notice the appearance of white spots or lines. Moreover, the nails may become dented.

Final Thoughts

Alopecia areata is harmless and doesn’t make you sick. However, hair loss may impact mood and well-being. Therefore, consult your physician today for a diagnosis. You might get better without treatment if you lose only a few patches of hair. However, severe cases may need medications to facilitate hair growth and suppress immunity.
