Several skin conditions are more common in persons with skin of color, including dermatosis papulosa nigra, pseudofolliculitis barbae, acne keloidalis nuchae, and keloids. Dermatosis papulosa nigra is a common benign condition characterized by skin lesions that do not require treatment, although several options are available for removal to address cosmetic concerns. Pseudofolliculitis barbae occurs as a result of hair removal. Altering shaving techniques helps prevent lesions from recurring. In acne keloidalis nuchae, keloidal lesions are found on the occipital scalp and posterior neck. Early treatment with steroids, antibiotics, and retinoids prevents progression. A key part of the management of keloids is prevention. First-line medical therapy includes intralesional steroid injections. The distinct structure of the hair follicle in blacks results in hair care practices that can lead to common scalp disorders. For example, chemical relaxers decrease the strength of hair and may cause breakage. Better patient education, with early diagnosis and treatment, often leads to better outcomes.

ABSTRACT: Skin of color, also known as ethnic skin, is described as skin of individuals of African, Asian, Hispanic, Native-American, Middle Eastern, and Pacific Island backgrounds. Differences in hair morphology, hair grooming, cultural practices, and susceptibility to keloid scarring exist within these populations and have been implicated in hair, scalp, and skin disorders. Acne keloidalis (AK), central centrifugal cicatricial alopecia (CCCA), dissecting cellulitis of the scalp (DCS), pseudofolliculitis barbae (PFB), traction alopecia (TA), and keloids are the most prevalent follicular and scarring disorders in skin of color. They have been associated with disfigurement, permanent hair loss, emotional distress, and decreased quality of life. Hair grooming practices, such as the use of chemical relaxers, heat straightening, and tight braiding and weaving can cause scalp irritation and follicular damage and are linked to the pathogenesis of some of these conditions. Consequently, patient education and behavior modifications are integral to the prevention and management of these disorders. Scarring disorders are also of concern in ethnic populations. Keloid scarring is more prevalent in individuals of African, Asian, and Hispanic descent. The scarring alopecia CCCA is almost exclusively seen in patients of African descent. Therapeutic regimens such as intralesional corticosteroids, surgical excision, and laser therapy can be effective for these follicular and scarring disorders, but carry a risk of dyspigmentation and keloid scarring. Ethnic skin and hair may present unique challenges to the clinician, and knowledge of these differences is essential to providing quality care.American Journal of Clinical Dermatology 05/2014; 15(4).

ABSTRACT: Dermoscopic examination of hair and scalp, also named "trichoscopy," is an essential tool in diagnosis of hair and scalp diseases. Trichoscopy is fast and noninvasive and can be used to evaluate hair disorders in all body areas. Body hair disorders are uncommon, and most publications on their dermoscopic features are limited to case reports or series. In this review we present the available information on the dermoscopic diagnosis of body hair disorders including keratosis pilaris, trichostasis spinulosa, pili multigemini, circle hairs, rolled hairs, eruptive vellus hair cyst, and ingrown hairs.
