Alopecia Areata: Causes, Symptoms, Diagnosis And Treatment

Alopecia areata is a common autoimmune disorder affecting people of all ages and ethnicities. It is characterised by sudden hair loss that starts in small, round patches. While these patches might not be initially noticeable, they can grow larger over time. In some cases, it leads to complete baldness, although the hair follicles remain intact, meaning that hair can regrow. However, the disease can be unpredictable, with regrowth not guaranteed.

The most common form of alopecia disease is patchy hair loss, but in severe cases, it can result in total hair loss across the scalp (alopecia totalis) or even the entire body (alopecia universalis).

Causes of Alopecia Areata

The alopecia areata causes can vary, and while the exact cause is unknown, several factors are believed to contribute to its development. These include:

• Genetics: A family history of autoimmune disorders can increase the risk of developing alopecia disease. Those with close relatives having autoimmune conditions are more likely to experience it.
• Immune system dysfunction: The body’s immune system mistakenly attacks healthy hair follicles, causing them to shrink and stop producing hair.
• Stress: Physical or emotional stress can sometimes trigger hair loss in individuals predisposed to the condition.
• Hormonal changes: Fluctuations in hormone levels, particularly during pregnancy or menopause, can exacerbate or trigger alopecia.
• Environmental factors: Certain environmental triggers, such as infections or toxins, may contribute to the onset of alopecia areata.

Symptoms of Alopecia Areata

Understanding the alopecia areata symptoms can help in early detection and management. Symptoms may present as:

1. Patchy hair loss

Small, round, bald patches appear on the scalp, beard, eyebrows, or other body parts.

2. Hair thinning

Gradual hair thinning may occur instead of sudden bald patches.

3. Nail changes

Some people with alopecia notice changes in their nails, such as pitting or ridges.

4. Burning or itching

Affected areas may feel itchy or have a burning sensation before hair loss occurs.

5. Excessive hair loss

Significant hair loss within a short span of time can sometimes be noticed during brushing or washing hair.

Diagnosis of Alopecia Areata

Accurate diagnosis is essential for proper treatment. Diagnosis of alopecia areata typically involves:

• Physical examination: A doctor will examine the areas of hair loss and check for patterns that indicate alopecia areata.
• Medical history: Your physician may ask about your family history and if there is any occurrence of autoimmune diseases.
• Scalp biopsy: In some cases, a small piece of scalp tissue may be taken to examine under a microscope and confirm the diagnosis.
• Blood tests: These tests may be done to check for underlying autoimmune conditions or other related health problems.
• Pull test: The doctor gently pulls on hair to determine how easily it comes out, which can help confirm the severity of hair loss.

Treatment Options for Alopecia Areata

There is no definitive cure for alopecia disease, but various treatment options can promote hair regrowth or manage symptoms. These treatments include:

1. Topical treatments

Medications like corticosteroids can be applied to the scalp to reduce inflammation and encourage hair regrowth.

2. Injectable treatments

Steroid injections directly into the affected areas of the scalp can stimulate hair growth.

3. Oral medications

In cases of severe alopecia areata, oral immunosuppressive drugs may be prescribed to help reduce the immune system’s attack on hair follicles.

4. Light therapy

Also known as phototherapy, this involves using ultraviolet light to treat areas affected by alopecia areata.

5. Minoxidil (Rogaine)

Over-the-counter minoxidil is sometimes recommended to stimulate hair growth, although its effectiveness varies from person to person.

6. Lifestyle changes

Managing stress through techniques such as meditation, yoga, and a healthy diet can sometimes help manage the condition.

7. Wigs and cosmetic solutions

For those with significant hair loss, wigs or hairpieces can provide an immediate cosmetic solution.

Conclusion

Living with alopecia areata can be challenging due to its unpredictable nature and impact on self-esteem. However, understanding the alopecia areata symptoms, causes, and treatment options can empower individuals to manage the condition effectively. Whether the hair loss is mild or severe, options like topical treatments, light therapy, or even lifestyle changes can offer support.
