I understand that alopecia hair loss affects millions globally, bringing emotional and psychological challenges. If you or someone you know is facing unexpected hair loss, it might be due to an autoimmune condition called alopecia areata. This condition occurs when the immune system mistakenly attacks hair follicles. The result can be patchy hair loss or, in severe cases, complete baldness of the scalp or the entire body. Recognizing the alopecia areata causes is key to understanding and managing this condition.

Grasping the different forms of alopecia areata, like alopecia totalis, and knowing the treatment options is essential for managing this condition effectively.

Alopecia areata can impact anyone, regardless of age, gender, or skin tone. It often starts with what's known as patchy alopecia in children and young adults but can begin at any age, representing a form of childhood alopecia that is particularly concerning for both parents and the affected youth.

The word "alopecia" means hair loss, and "areata" describes the patchy pattern of this condition. For those with alopecia totalis, losing all scalp hair is particularly challenging. In this article, I will guide you through the symptoms, causes, diagnosis, and treatment options for alopecia hair loss, helping you navigate this complex condition.

Symptoms and Causes

Alopecia areata shows up with noticeable and often sudden symptoms. The main sign is round or oval, smooth bald patches on the scalp or other body parts.

These patches are usually the size of a coin and can appear on the scalp, beard, eyebrows, or eyelashes. Unlike other types of hair loss, these patches typically do not have signs of irritation like swelling, rash, or redness.

Besides visible hair loss, some may feel itching, tingling, or burning in areas where hair is falling out. Nail changes are also common, such as tiny dents, ridges, brittleness, or nails feeling rough. About 10% to 20% of people with alopecia areata experience these nail changes.

The progression of alopecia areata varies. Some experience small isolated patches, while others see these patches connect or spread to other body areas.

In severe cases, this can lead to alopecia totalis, with all scalp hair lost, or alopecia universalis, with all body hair lost.

Alopecia areata is an autoimmune disease. This means the immune system mistakenly attacks hair follicles, leading to alopecia patches. The exact alopecia causes in females and other individuals are not fully clear, but several factors contribute to its development, including hormonal changes that might lead to hormonal alopecia.

Genetics play a significant role. If you have a family history of alopecia areata or other autoimmune diseases, your risk increases.

Other triggers might include environmental factors like bacterial or viral infections and certain medications. Additionally, having other autoimmune conditions such as asthma, Down syndrome, pernicious anemia, seasonal allergies, thyroid disease, or vitiligo raises the risk of developing alopecia areata.

Stress is also considered a possible trigger, though its relationship with the condition isn't fully understood. There is a growing body of evidence suggesting alopecia caused by stress is more common than previously thought, affecting the overall stress load on an individual.

The immune system's attack doesn't destroy hair follicles, allowing for hair regrowth. However, the extent and frequency of regrowth vary among individuals.

Some people may see spontaneous regrowth, while others might need treatment to stimulate hair growth.

Diagnosis and Tests

Diagnosing alopecia areata starts with a thorough assessment by a dermatologist. This includes a visual examination of the hair loss areas and an inspection of the nails, as nail changes are common in alopecia areata.

The dermatologist looks for signs like round or oval bald patches, smooth skin in affected areas, and nail abnormalities such as dents, ridges, or brittleness.

During the assessment, the dermatologist will also inquire about your medical and family history to identify any genetic predispositions or related autoimmune conditions. Discussing your health history, including past illnesses or medications, helps rule out other causes of hair loss.

Simple tests like the pull test and tug test may be conducted. The pull test involves gently pulling small sections of hair to assess hair loss severity. The tug test checks for hair brittleness by tugging on strands to see if they break.

In some cases, advanced diagnostic tools are needed. A dermatoscope, a handheld magnifying device, provides a closer look at hair follicles and the scalp.

Trichometric analysis using tools like the Folliscope® involves a high-definition microscopic camera to capture detailed images of the scalp and hair. This method allows up to 100x magnification for precise analysis of hair coverage, follicle health, and scalp condition.

If the diagnosis remains unclear, blood tests may be ordered to check for underlying conditions like thyroid disease, iron deficiency, or other vitamin and mineral deficiencies contributing to hair loss. A skin biopsy, removing a small skin sample for microscopic examination, may also help distinguish between different types of hair loss, especially if there are scalp lesions or scarring.

Additionally, a fungal culture might be recommended if a fungal infection like tinea capitis (scalp ringworm) is suspected. This involves scraping or swabbing the scalp and sending the sample to a laboratory for testing.

Management and Treatment

Managing alopecia areata often involves a mix of conventional treatments aimed at reducing inflammation, suppressing the immune system's attack on hair follicles, and stimulating hair growth. Corticosteroids are among the most common treatments. They can be administered as intradermal injections directly into affected areas, topical applications like creams, ointments, or gels, or oral medications for severe cases.

Topical corticosteroids work better in children than in adults and are often the first-line treatment for patchy hair loss. Scalp injections of corticosteroids can be effective for adults, with hair regrowth usually seen within three months of the first injection.

For widespread hair loss, systemic corticosteroids like prednisone may be prescribed, though they are reserved for severe cases due to potential side effects.

Other conventional treatments include minoxidil (£0.00), applied to the scalp to help maintain hair regrowth after initial treatments. Anthralin and diphencyprone (DPCP) are also used, though they can cause skin irritation and are typically combined with other treatments like minoxidil.

Janus kinase (JAK) inhibitors, such as baricitinib, deuruxolitinib, and ritlecitinib, are FDA-approved for treating severe alopecia areata. These medications calm the overactive immune system, allowing significant hair regrowth, including eyebrows and eyelashes.

Beyond conventional treatments, several innovative and supportive therapies are emerging. One promising approach uses microneedle patches to deliver immune-regulating molecules directly to the scalp. This teaches T cells not to attack hair follicles, promoting regrowth. Studies in mice have shown promise, reducing inflammation and allowing hair regrowth without systemic immune effects.

Other innovative treatments include platelet-rich plasma (PRP) patches, which involve injecting PRP into the scalp to stimulate hair growth. Additionally, topical retinoids, cryotherapy, and light-based therapies like excimer light are being explored for managing alopecia areata.

For those preferring non-pharmacological approaches, photochemotherapy and certain natural remedies might be considered, though they lack extensive proof. Photochemotherapy uses light and a photosensitizing agent to treat affected areas. Natural remedies like onion or garlic juice, cooled green tea, almond oil, and rosemary oil are sometimes used by patients seeking alternative treatments.

Supportive therapies are essential for managing the emotional and psychological impact of alopecia areata. Counseling, support groups, and cosmetic solutions such as wigs, hairpieces from Simmys Wigs, and semi-permanent tattoos help individuals cope and maintain self-esteem and quality of life.

Conclusion

Alopecia areata is a complex and unpredictable autoimmune disease causing patchy or complete hair loss in individuals of all ages. It’s important to recognize that alopecia areata affects both physical and emotional well-being. The condition is marked by the immune system mistakenly attacking healthy hair follicles, leading to symptoms like round or oval bald patches, nail changes, and occasional sensations of itching or burning.

While there is no cure, various treatments including corticosteroids, minoxidil, and newer medications like JAK inhibitors can help stimulate hair regrowth. Consulting a dermatologist is essential for an accurate diagnosis and exploring the most suitable treatment options.

Supportive therapies and counseling also play a vital role in managing the condition.

If you or someone you know is experiencing alopecia areata, seek medical advice and support. Early intervention and the right treatment can significantly impact managing the condition and promoting hair regrowth.

Remember, alopecia areata does not reflect overall health. With proper care and support, individuals can effectively navigate this condition.

FAQ

What is the best way to treat alopecia?

The best treatment for alopecia areata depends on its severity and the individual case. For mild cases, topical minoxidil or corticosteroid injections may work well.

For extensive hair loss, treatments like topical immunotherapy or Janus kinase (JAK) inhibitors such as baricitinib, deuruxolitinib, and ritlecitinib are often recommended.

What triggers alopecia?

Alopecia areata is triggered by the immune system attacking hair follicles, likely due to a mix of genetic and environmental factors. Specific triggers may include extreme stress or anxiety, although this isn't fully proven. It's also linked to other autoimmune diseases like thyroid disease, vitiligo, asthma, and eczema.

Can your hair grow back if you have alopecia?

Yes, hair can regrow with alopecia areata. Many people, especially those with a few patches of hair loss, see hair regrowth within six to twelve months, either naturally or with treatment. However, relapses are common, and the condition can recur throughout a person's life.
