Alopecia areata (AA) is a common autoimmune skin disease characterized by non-scarring hair loss that can affect the scalp, face, and other areas of the body. The term "alopecia" means bald, while "areata" means patchy, aptly describing the condition's typical presentation. Affecting approximately 2% of the global population, or an estimated 160 million people worldwide, AA transcends age, gender, and racial and ethnic boundaries. While it can manifest at any stage of life, the onset of alopecia areata often occurs early, with over 80% of individuals exhibiting signs before the age of 40 and 40% experiencing symptoms by age 20.
Recent evidence suggests a potentially higher prevalence of AA in people with skin of color. Moreover, studies indicate that women are more likely to develop alopecia areata than men. Racial and ethnic disparities also exist, with Asian individuals experiencing the highest lifetime incidence of alopecia areata and Black individuals facing a disproportionately higher risk of anxiety disorders associated with the condition. This article delves into the specific manifestations, diagnostic considerations, and management of alopecia areata in Black men, highlighting the unique challenges and insights relevant to this population.
Alopecia areata is an autoimmune disease, meaning the body's immune system mistakenly attacks healthy hair follicles. Although scientists know it is an autoimmune disease, they aren’t sure why the immune system attacks the healthy hair follicles of people with the gene variations in the first place. The exact triggers of this immune response remain unclear, but research suggests a complex interplay of genetic predisposition and environmental factors. About 20% of people with alopecia areata have at least one family member who also has the disease. The risk of alopecia areata increases if you have a close relative with it. Potential triggers may originate from within the body, such as bacteria or viruses, or from external environmental factors, or a combination of both.
Alopecia areata is diagnosed based on your symptoms (hair loss and pattern). The hallmark of AA is typically the sudden appearance of circular, coin-sized patches of hair loss on the scalp. In more severe cases, the condition can progress to complete hair loss on the scalp (alopecia totalis) or the entire body (alopecia universalis). The hair often grows back white. The condition appears to occur more commonly in people with darker hair. It’s cause may be due to an autoimmune reaction to hair pigment.
In addition to your symptoms, your doctor will want to take a family history and your medical history to rule out other things that could cause hair loss. Doctors who specialize in skin conditions, called dermatologists, treat alopecia areata. When looking for a dermatologist, look for one who is board-certified in dermatology.

Unlike most autoimmune diseases, alopecia areata does not generally cause physical discomfort or disability. However, hair loss can be difficult for many people. It can have a significant impact on their mental health, affecting how they feel about themselves. Having alopecia areata can be frustrating and emotionally challenging because hair loss and regrowth are unpredictable. Different people have different ways of coping with their hair loss. Some wear wigs or use camouflage techniques to hide the bald areas, while others don’t bother hiding it at all.
Notably, a study published in the British Journal of Dermatology revealed that alopecia areata has a greater impact on the mental health and work-related outcomes of non-White individuals compared with White individuals. Increased risk of mental health conditions is typical among patients with alopecia, with previous research demonstrating a 33% greater risk of new-onset anxiety and a 38% higher risk of depression. Data show patients with alopecia areata are 56% more likely to have to take time off work and 82% more likely to be unemployed.
Hair loss affects people of all ethnic groups. African Americans, however, can be predisposed to certain types of hair loss. In African Americans, hair loss can occur due to various reasons, including the unique characteristics of kinky hair, certain hairstyles, and underlying medical conditions. It’s important for black, or African American people with hair loss to get help from professionals with knowledge and experience in caring for their specific hair texture.
African Americans have a variety of hair textures. They more commonly have the more unique hair texture of kinky hair. Kinky hair, also known as coily or curly hair, has a distinct spiral shape that makes it more susceptible to damage, breakage, and hair loss. Moreover, the use of harsh chemicals, such as relaxers and straightening agents, can further damage the hair.
Traction alopecia is a type of hair loss that occurs due to prolonged tension on the hair follicles. Common hairstyles associated with the condition include buns, braids, hair extensions, weaves, and dreadlocks. It is more common in African Americans due to the frequent use of these hair care practices. The constant pulling and tugging on the hair can damage the hair follicles, leading to hair breakage, thinning, and bald spots. To prevent traction alopecia, it’s essential to avoid tight hairstyles that pull on the hair, such as tight braids, weaves, and extensions.

Central centrifugal cicatricial alopecia (CCCA) is a type of scarring hair loss that primarily affects women of African descent. CCCA usually starts at the crown of the head and spreads outward in a centrifugal pattern. CCCA is associated with a history traction from tight or heavy hair styles, such as braids, weaves, extension or dreadlocks, in a susceptible person. The exact cause of CCCA is unknown, but it’s believed to be a combination of genetic, hormonal, and environmental factors. Early diagnosis and treatment are crucial to prevent permanent hair loss and scarring. Treatment options for CCCA may include protective hair styling, topical or oral medications, steroid injections, or surgical hair restoration.
Acne keloidalis nuchae is a chronic skin condition that primarily affects African American men. It’s characterized by the formation of hard, painful bumps on the back of the scalp and neck. These lesions can lead to scarring, keloids and hair loss. The exact cause of acne keloidalis nuchae is believed to be linked to inflammation in the hair follicles that occurs from the trauma of curly and kinky hair curling back into the skin.
Dissecting cellulitis, also known as perifolliculitis capitis abscedens et suffodiens, is a rare inflammatory condition that affects hair follicles on the scalp. While the exact cause of dissecting cellulitis is unknown, it is believed to be related to abnormalities in the hair follicle, including increased sebum production and blockage. The condition may also worsen due to bacterial superinfection. Dissecting cellulitis can be a chronic condition that can be difficult to treat. Early intervention and a combination of medical and surgical approaches may help to manage symptoms and prevent further hair loss.
Tinea capitis is a fungal infection of the scalp that can cause hair loss, scaling, and itching. It is more commonly seen in children. Studies have suggested that African American children may be at a higher risk of developing tinea capitis due to differences in hair texture and structure, which can create an environment that is more conducive to fungal growth. Diagnosis of tinea capitis requires a fungal culture.
Diagnosing AA in Black men can be challenging due to the potential overlap with other hair loss conditions prevalent in this population, such as traction alopecia and CCCA. It is crucial for clinicians to thoroughly review symptoms as well as clinical and trichoscopic findings and have an appropriate threshold for scalp biopsy when there is concern for a scarring process.

A retrospective analysis of trichoscopic images and medical records of 10 Black patients with a clinical diagnosis of AA revealed several key findings:
This study underscores the need for improved understanding and documentation of AA in Black individuals. Identification of trichoscopic features in AA will aid physicians with diagnosis and decrease the threshold for diagnosis of co-existing alopecias.
CCCA, a scarring alopecia predominantly affecting women of African ancestry, can sometimes be misdiagnosed as androgenetic alopecia (AGA) in Black men. Both conditions can initially present as hair thinning on the vertex scalp. However, there are key clinical distinctions:
Three cases of biopsy-supported CCCA in Black men highlight the importance of considering this diagnosis in men presenting with hair loss on the vertex scalp:
These cases highlight a key clinical distinguishing feature of male CCCA, demonstrating notable thinning on the vertex scalp with relative maintenance of the hairline, a feature that is yet to be noted in previous literature and can help clinicians more easily differentiate this form of scarring alopecia in Black men from AGA.
Alopecia areata can have a significant impact on mental health, particularly among non-White individuals. Studies have shown that Black individuals with alopecia areata face a disproportionately higher risk of anxiety disorders.
It is crucial for healthcare professionals to recognize the psychological burden of AA and provide appropriate support and resources. Encouraging open communication, connecting patients with support groups, and offering referrals for psychological therapy can help individuals cope with the emotional challenges associated with hair loss.
The history of racism in American has sometimes manifested as discrimination against people with kinky and curly hair. In addition to the negative emotional and economic impact, hair discrimination can be a cause of hair loss. The CROWN Act, which stands for “Creating a Respectful and Open World for Natural Hair,” is a law that prohibits discrimination based on hairstyle or hair texture. Specifically, the CROWN Act seeks to end discrimination against people who wear their hair in natural styles. The act aims to ensure that people are not subjected to unequal treatment, bias, or ridicule in the workplace or other settings because of their hair. The CROWN Act has been passed in several states in the United States, including California, New York, New Jersey, Virginia, Colorado, Washington, Maryland, and others, as well as in several cities and counties.
