Hair loss is a common concern that affects individuals across all ethnic groups. However, Black men may experience hair loss differently due to unique hair characteristics, cultural practices, and specific conditions. Understanding the various causes, available treatments, and special considerations is essential for effectively managing hair loss in this population.
Several factors can contribute to hair loss in Black men, including:
African Americans often have kinky hair, characterized by a distinct spiral shape. This unique structure makes the hair more susceptible to damage and breakage. The use of harsh chemicals, such as relaxers and straightening agents, can further weaken the hair, increasing the risk of hair loss.
Certain hairstyles and hair care practices commonly used within the Black community can contribute to hair loss. These include:
Traction alopecia is a type of hair loss caused by prolonged tension on the hair follicles. Hairstyles like tight braids, weaves, extensions, buns, and dreadlocks can exert excessive pulling on the hair, leading to damage, breakage, thinning, and bald spots. To prevent traction alopecia, it is crucial to avoid tight hairstyles and give the hair follicles a break.

CCCA is a scarring type of hair loss that primarily affects women of African descent, but it can also occur in men. The exact cause of CCCA is unknown, but it is believed to be a combination of genetic, hormonal, and environmental factors. CCCA often starts at the crown of the head and spreads outwards. It has been associated with traction from tight or heavy hairstyles. Early diagnosis and treatment are essential to prevent permanent hair loss and scarring. Treatment options may include protective hair styling, topical or oral medications, steroid injections, or surgical hair restoration.
Certain medical conditions can also contribute to hair loss in Black men:
Acne keloidalis nuchae is a chronic skin condition that primarily affects African American men. It is characterized by hard, painful bumps on the back of the scalp and neck, which can lead to scarring, keloids, and hair loss. The condition is believed to be linked to inflammation in the hair follicles caused by 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 affecting hair follicles on the scalp. While the exact cause is unknown, it is believed to be related to abnormalities in the hair follicle, including increased sebum production and blockage. Bacterial superinfection can worsen the condition. Dissecting cellulitis can be chronic and difficult to treat, requiring early intervention and a combination of medical and surgical approaches to manage symptoms and prevent further hair loss.
Alopecia areata is an autoimmune condition that causes non-scarring hair loss in smooth, round patches. While it affects people of all races, it may appear more commonly in people with darker hair due to a possible autoimmune reaction to hair pigment. In alopecia areata, the hair often grows back white.

Tinea capitis is a fungal infection of the scalp that can cause hair loss, scaling, and itching. Studies suggest 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 conducive to fungal growth. Diagnosis requires a fungal culture.
Male androgenetic alopecia (MAA), also known as male pattern baldness, is the most common cause of hair loss in men, including Black men. It is a hereditary condition characterized by a receding hairline and thinning hair on the crown of the head.
MAA affects an estimated 30% to 50% of men by age 50. While the prevalence of MAA tends to be lower among Black men compared to white men, it is still a significant concern. Black, Oriental, Native American, and African-American men are more likely to have preservation of their frontal hair lines, less extensive and late onset baldness than Caucasians.
MAA is caused by a combination of genetic predisposition and hormonal factors. Androgens, particularly dihydrotestosterone (DHT), play a crucial role in the development of MAA. DHT binds to androgen receptors in the hair follicles, causing them to shrink and produce thinner, shorter hairs. Over time, the hair follicles may stop producing hair altogether.
The key pathophysiological features of MAA are alteration in hair cycle development, follicular miniaturization, and inflammation. In MAA, the anagen phase decreases with each cycle, while the length of telogen remains constant or is prolonged. Ultimately, anagen duration becomes so short that the growing hair fails to achieve sufficient length to reach the surface of the skin, leaving an empty follicular pore. Hair follicle miniaturization is the histological hallmark of androgenetic alopecia.

A receding hairline can be initially diagnosed by observing the pattern of hair loss. Looking at your current hairline and comparing it with pictures that show a more forward hairline can be helpful. Diagnosis of MAA is typically based on the characteristic pattern of hair loss. In some cases, a skin biopsy or blood test may be needed to rule out other underlying conditions.
Several treatment options are available for MAA, including:
Combining medications with different mechanisms of action enhances the efficacy. Topical antiandrogens, prostaglandin analogues, topical antifungals, growth factors, and laser treatment are all emerging medical treatments for MAA, yet lack the necessary research to confirm efficacy and safety.
Hair transplantation involves removing hair from the occipital scalp and re-implantation into the bald vertex and frontal scalp. With modern techniques, graft survival in excess of 90% can be reliably achieved. A combination of these therapeutic options is now available for men experiencing MAA, with favorable cosmetic outcomes possible.
Alopecia areata is an autoimmune disease that causes patchy hair loss on the scalp, face, and sometimes other body areas. It affects people of all ages, genders, and racial and ethnic groups.
Alopecia areata causes hair to fall out in patches, usually small and round. The nails may also develop dents or pits. Diagnosis is based on symptoms, family history, and medical history.
There are many different classifications of alopecia areata. The classifications depend on the amount of hair you’ve lost and where you’ve lost it on your body.
Treatment options for alopecia areata may include topical or oral medications, steroid injections, or other therapies to stimulate hair follicles.
Central centrifugal cicatricial alopecia (CCCA) is a scarring alopecia that disproportionately affects women of African ancestry. However, it can also occur in Black men, although it may be underdiagnosed in this population.
CCCA typically manifests as hair thinning at the midline portion of the vertex scalp, progressing over time in a centrifugal pattern. In Black men, a key clinical distinguishing feature of CCCA is notable thinning on the vertex scalp with relative maintenance of the hairline.
Diagnosis of CCCA requires clinicopathologic correlation, including a scalp biopsy to differentiate it from other forms of alopecia, such as androgenetic alopecia (AGA).
Early and accurate diagnosis and treatment initiation are essential for managing CCCA and preventing permanent hair loss. Treatment options may include topical or oral medications, steroid injections, and lifestyle modifications.
The history of racism in America 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. 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.
Hair is an essential part of an individual's self-image and its main significance relates to socialization. Thus, the consequences of MAA are predominantly psychological. Hair loss can have a significant impact on mental health, affecting how people feel about themselves. It is important for physicians to address the patients’ emotional responses to alopecia, including anger, anxiety, and depression, including their beliefs about the impact of their condition.
MAA has been reportedly associated with increased incidence of myocardial infarction, hypertension, and hypercholesterolemia. An increased incidence of benign prostatic hyperplasia has been associated with MAA, and MAA could be an early marker of the disease. Prostate cancer has also been found to be positively associated with MAA in various studies. Recent studies suggested both high and low androgen levels could lead to a severe course of COVID-19.
