Alopecia Areata - Dr Colin Hong

Alopecia areata is a common, non-contagious autoimmune skin condition that causes patchy hair loss on the scalp and other parts of the body. It affects both men and women of all ages and ethnicities but is most commonly seen in adolescents. The exact cause is unknown, but researchers believe it could be linked to genetics or an underlying medical condition. There are several different types of alopecia areata, ranging from mild forms such as limited patches of hair loss to more severe cases which can result in complete baldness.

Treatment options vary depending on severity and range from topical creams, steroid injections, prescription medications, light therapy and even surgical procedures. While there is no cure for alopecia areata, it can be managed to help prevent further hair loss. Here, we’ll discuss the causes and symptoms of alopecia areata, as well as available treatments and tips for managing the condition. 

History and Definition

Alopecia areata is a type of hair loss that affects the scalp and other hair-bearing areas of the body. It is considered an autoimmune condition, meaning that the immune system mistakenly attacks the hair follicles, causing hair loss. The first recorded use of the term “alopecia areata” was by French physician Sauvages de Lacroix in 1763.

The exact cause of the condition is unknown, but it is believed to be a combination of genetic and environmental factors. Alopecia areata can be treated with a variety of methods, including topical or injected corticosteroids, minoxidil, and immunotherapy. In severe cases, hair transplantation may be necessary.


The main symptom of alopecia areata is sudden and rapid hair loss, typically in round patches on the scalp. Other symptoms may include:

  • Thinning hair or total baldness
  • Broken hairs that form a distinctive “exclamation point” shape
  • Itching or burning sensation in affected areas
  • Presence of small, firm, round bumps on the scalp (called “Alopecia Areata Nodules”)
  • Loss of hair on other parts of the body, including eyebrows, beard, and pubic hair
  • Rapid regrowth of hair in some areas, followed by new hair loss in other areas.

The symptoms of alopecia areata vary from person to person, and some people may not have any symptoms at all besides hair loss.


Alopecia areata is an autoimmune disorder which causes hair loss. It can affect any part of the body and can vary in severity. The exact cause of alopecia areata is unknown, but there may be a genetic component as it can sometimes run in families.

Other possible causes include environmental triggers such as stress or exposure to certain chemicals or medications. Additionally, some research suggests that hormonal imbalances may also contribute to the development of this condition. 

Ultimately, all these factors may combine to cause an over-reactive immune system response that attacks the hair follicles and causes them to fall out prematurely.


Diagnosis usually involves a physical examination of the affected area and sometimes a blood test to check for any underlying medical conditions, such as anemia or thyroid disease. A skin biopsy may also be performed if necessary.


Treatment for alopecia areata typically includes topical or injected corticosteroids, intralesional steroid injections, and topical immunotherapy.


Surgery is sometimes recommended as a treatment option for people with extensive baldness caused by alopecia areata; however, it is not always successful in regrowing lost hair. In most cases, surgery involves removing large sections of existing scalp with bald patches and replacing them with skin grafts taken from other areas of the body.

After surgery, patients may experience some pain and discomfort. They will also need to take medications to reduce inflammation and prevent infection. Patients should expect to limit their physical activity during recovery as well. Additionally, scarring is possible, so it is important to follow your doctor’s instructions for post-operative care carefully.

Regaining hair after surgery usually takes several months or longer. Follow up visits are essential in order to monitor the healing process and gauge the effectiveness of the procedure. It may be necessary for additional treatments if hair does not regrow sufficiently or if new bald patches appear.

Overall, alopecia areata can be a difficult condition but with proper diagnosis and treatment, it can be managed. Speak to your doctor about the best treatment options for you, and take steps to look after yourself and manage any associated stress or anxiety. With patience and dedication, regrowth of hair is possible. 

Risk Factors

Alopecia areata can affect anyone, at any age, but is more commonly seen in people under 30 years old.

Common risk factors for developing alopecia areata include:

  • family history
  • certain medical conditions (such as thyroid disease and anemia) 
  • high levels of stress, and exposure to certain chemicals or drugs.

People with weakened immune systems are also at an increased risk for developing this condition. In rare cases, alopecia areata can be triggered by traumatic events such as surgery or severe emotional distress.


Complications of alopecia areata can be both physical and emotional. Physically, the condition can lead to permanent hair loss from a particular area or from the entire body. This type of hair loss is referred to as alopecia totalis or universalis and may cause significant disfigurement or embarrassment for those affected. In addition, permanent skin damage such as scarring may result from excessive scratching in areas where hair has fallen out due to itching associated with the condition.

Emotionally, alopecia areata can be devastating for individuals who experience it, leading to low self-esteem, anxiety and depression. Social ostracism may also occur in some cases due to negative reactions from other people who are unfamiliar with the condition. In some cases, people may even experience an increased risk of suicidal thoughts or behavior due to the emotional effects of alopecia areata.

To combat these complications, it is important for those affected to seek support from family and friends, as well as from mental health professionals. Furthermore, talking to a physician about management strategies can be beneficial in helping reduce physical and emotional symptoms associated with alopecia areata.

When to See a Doctor

If you have noticed any unusual patterns of hair loss, it is important to see a doctor as soon as possible. Alopecia areata can appear quickly and without warning, so if you notice any changes in the amount or pattern of your hair loss, even if it looks like normal shedding, it is important to get checked out by a doctor. 

It’s also important to consult with a doctor if you are experiencing other symptoms such as:

  • itching 
  • burning 
  • pain on the scalp

A doctor may be able to diagnose alopecia areata based on your physical appearance alone and order further tests if necessary.

Step-by-Step Guide to Alopecia Areata Treatment

This step-by-step guide to alopecia areata treatment provides an overview of the steps you can take to manage your condition and achieve successful treatment outcomes.


It is important to consult a doctor or a plastic surgeon who specializes in alopecia areata. They will evaluate the current condition of your scalp, look at your medical history, and perform a physical examination. This consultation will help them determine if you have alopecia areata or another type of hair loss disorder.


Your doctor may suggest topical medications or light therapy such as PUVA (psoralen + ultraviolet A). These treatments are intended to slow down the progression of alopecia areata and improve hair regrowth. In some cases, steroids may be used in injection form or topical creams.


If the hair loss is extensive or if there are no other treatments that are effective, your doctor may suggest a surgical procedure known as scalp reduction surgery. This involves removing a portion of the scalp with balding areas and then stitching the remaining portions together to reduce the amount of baldness.

Follow-Up Visits

After any type of treatment for alopecia areata, it is important to keep up with follow-up visits in order to monitor the response to therapy and look for potential side effects or complications from medications or surgery. Additionally, these visits can help you make sure that you are taking all necessary steps to prevent further hair loss. 

It is important to remember that although there currently is no cure for this condition, treatment and lifestyle changes can help minimize hair loss and promote regrowth. With the right care, it is possible to gain back some of your lost self-confidence and enjoy a more normal appearance.


In conclusion, alopecia areata is a common and treatable autoimmune disorder that can cause hair loss on the scalp and other parts of the body. Although there is no cure for it yet, there are treatments available to help control symptoms. 

It’s important to remember that if you or someone you know has this condition, they’re not alone; many people experience alopecia areata in varying degrees and can take comfort in knowing that support is available. With proper management and care, those living with alopecia areata can look forward to better quality of life.
