Diagnosing and Treating Hair Loss - Article
ABSTRACT: Physicians should be careful not to underestimate the emotional impact of hair loss for some patients. Patients may present with focal patches of hair loss or more diffuse hair loss, which may include predominant hair thinning or increased hair shedding. Focal hair loss can be further broken down into scarring and nonscarring. Scarring alopecia is best evaluated by a dermatologist. The cause of focal hair loss may be diagnosed by the appearance of the patch and examination for fungal agents. A scalp biopsy may be necessary if the cause of hair loss is unclear. Alopecia areata presents with smooth hairless patches, which have a high spontaneous rate of resolution. Tinea capitis causes patches of alopecia that may be erythematous and scaly. Male and female pattern hair losses have recognizable patterns and can be treated with topical minoxidil, and also with finasteride in men. Sudden loss of hair is usually telogen effluvium, but can also be diffuse alopecia areata. In telogen effluvium, once the precipitating cause is removed, the hair will regrow.
Medical Treatments for Balding in Men - Article
ABSTRACT: Two drugs are available for the treatment of balding in men. Minoxidil, a topical product, is available without a prescription in two strengths. Finasteride is a prescription drug taken orally once daily. Both agents are modestly effective in maintaining (and sometimes regrowing) hair that is lost as a result of androgenic alopecia. The vertex of the scalp is the area that is most likely to respond to treatment, with little or no hair regrowth occurring on the anterior scalp or at the hairline. Side effects of these medications are minimal, making them suitable treatments for this benign but psychologically disruptive condition.
A Lesion That Should Raise Suspicion - Photo Quiz
ABSTRACT: 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.
