Understanding the Autoimmune Disorder that Causes Hair Loss

Alopecia, also known as spot baldness, is a medical condition characterized by hair loss in one or more areas of the body. It is an autoimmune disorder that occurs when the body’s immune system mistakenly attacks hair follicles, leading to hair loss. Alopecia can affect people of all ages, genders, and ethnicities, and it is estimated that about 6.8 million people in the United States alone have alopecia areata, the most common form of the condition. 

While hair loss is a common issue that many people experience at some point in their lives, alopecia is a distinct medical condition that requires a proper diagnosis and treatment plan. Alopecia is caused by an autoimmune disorder. This means that the body’s immune system mistakenly attacks hair follicles, leading to hair loss in one or more areas of the body. 

There are several different types of alopecia, each with its own set of symptoms and treatment options. The most common form is alopecia areata, which is characterized by round patches of hair loss on the scalp, face, and other parts of the body. Other forms include alopecia totalis (total hair loss on the scalp) and alopecia universalis (total hair loss on the scalp, face, and body). 

The hair loss in alopecia is usually sudden and can be accompanied by itching, burning, or a tingling sensation. The patches of hair loss may also be accompanied by broken hair or “exclamation point” hairs (short, tapered hairs at the edge of the bald patch) affecting all people of all ages, genders and ethnicity. It is estimated that about 2% of the world’s population is affected by alopecia areata. The exact incidence of alopecia areata in the Philippines is not well-documented, but it is estimated that it affects around 0.1-0.2% of the population. This is similar to the estimated incidence of alopecia areata in other countries.  

The exact cause of alopecia is not fully understood. However, it is believed to be a combination of genetic, environmental, and immune factors. 

Research suggests that people with alopecia areata have a higher incidence of certain genes. Some studies also show an increased risk of other autoimmune disorders, such as thyroid disease, lupus, and rheumatoid arthritis, suggesting a link between the immune system and the development of alopecia. 

Some environmental factors have also been linked to the development of alopecia, such as exposure to certain chemicals, stress, and viral infections. Some viral infections may trigger an immune response that leads to the development of alopecia. 

Alopecia is not caused by poor hygiene or a lack of hair care. It is not contagious and not caused by lifestyle choices. 

Currently there is no cure for alopecia, but there are a variety of treatment options available that can help to manage the condition and improve the chances of hair regrowth. 

One of the most common treatments for alopecia areata is the use of topical corticosteroids. These medications are applied directly to the affected areas of the scalp and work by reducing inflammation and suppressing the immune system. Topical corticosteroids are typically used in the early stages of alopecia and can be effective in promoting hair regrowth in around 50% of patients. 

Another treatment option is the use of topical minoxidil, a medication that is applied directly to the scalp and is believed to increase blood flow to the hair follicles and promote hair growth. Minoxidil is typically used in combination with other treatments and can be effective in promoting hair regrowth in around 30-40% of patients. 

In more severe cases of alopecia, patients may be prescribed oral corticosteroids or immunosuppressant medications. These medications are taken orally and work by suppressing the immune system and reducing inflammation. These medications can have serious side effects, and it’s important to discuss the risks and benefits with your doctor. 

Another treatment option for alopecia is phototherapy, which involves exposing the affected areas of the scalp to ultraviolet light. Phototherapy can be effective in promoting hair regrowth in around 20-30% of patients. 

In addition to these treatments, there are a variety of hair loss concealers and hairpieces available that can help to camouflage the affected areas of the scalp and improve self-esteem. 

It’s worth noting that not all treatments are effective for everyone, and it may take some time to find the right treatment plan. It is important to consult a specialist and work together to find the best treatment plan for you. 

While there is currently no known way to prevent alopecia, there are some things you can do to reduce your risk of developing the condition, such as: 

• Managing stress levels: Stress can trigger or worsen alopecia, and it’s important to find ways to manage stress levels, such as through exercise, meditation, or therapy. 

• Eating a healthy diet: A healthy diet rich in fruits, vegetables, and lean protein can help to support overall health and reduce the risk of autoimmune disorders. 
• Avoiding harsh hair treatments: Using harsh hair treatments, such as hair dyes, relaxers, and hot tools, can damage hair and increase the risk of hair loss. 
• Avoiding tight hairstyles: Wearing tight hairstyles, such as braids, ponytails, and cornrows, can put strain on the hair and increase the risk of hair loss. 
• Avoiding certain medications: Certain medications, such as blood thinners, antidepressants, and birth control pills, can increase the risk of hair loss. If you’re concerned about hair loss while taking a medication, speak with your doctor.

If you suspect that you may have alopecia, it is important to consult a dermatologist for a proper diagnosis and treatment plan.
