A scalp biopsy may be necessary if the cause of hair loss is unclear.

The cause of focal hair loss may be diagnosed by the appearance of the patch and examination for fungal agents. These patches can take many shapes but are most usually round or oval.

Typical first symptoms of alopecia areata are small bald patches the underlying skin looks superficially normal. Alopecia areata (AA) is a medical condition in which hair is lost from some or all areas of the body, usually from the scalp. The clinical presentation is typically a single or multiple patches of hair loss, sometimes with a “black dot” pattern, that may be accompanied by inflammation, scaling, pustules, and itching. The disease is primarily caused by dermatophytes in the Trichophyton and Microsporum genera that invade the hair shaft. Tinea capitis is a superficial fungal infection of the scalp.

The clinician must be able to separate the types and causes of hair loss into those that reflect primary dermatologic conditions and those that represent reaction to systemic disease. The most frequent causes of hair loss in pediatric patients include tinea capitis, alopecia areata, traction alopecia, and trichotillomania. Losing hair is not usually health threatening it can scar a young child’s vulnerable self-esteem by causing immense psychological and emotional stress, not only to the patient, but also to the concerned parents and siblings so the cause of hair loss should be diagnosed and treated early to overcome the resulting problems. Trichoscopy can be used as a noninvasive tool for rapid diagnosis of tinea capitis and alopecia areata in pediatric patients. While in alopecia areata patients, the most trichoscopic specific features were yellow dots, exclamation mark, and short vellus hairs. Our obtained results reported that, in tinea capitis patients, comma shaped hairs, corkscrew hairs, and zigzag shaped hairs are the diagnostic trichoscopic features of tinea capitis. They were exposed toclinical examination, laboratory investigations (10% KOH and fungal culture), and trichoscope examination. This study included 40 patients, 20 patients with tinea capitis and 20 patients with alopecia areata. Aiming to compare the different trichoscopic features of tinea capitis and alopecia areata in pediatric patients. Like clinical dermatology, trichoscopy works parallel to the skin surface and perpendicular to the histological plane like the histopathology, it thus allows the viewing of structures not discovered by the naked eye. Trichoscopy is a rapid and noninvasive tool to detect more details of patchy hair loss. Diagnosis of patchy hair loss in pediatric patients is often a matter of considerable debate among dermatologists. We concluded that the most common cause of tinea capitis in South Africa is T. Twenty percent of the children presented with more than one clinical type simultaneously. The most common clinical variety was the “black dot” type, seen in 50% of patients. Wood light was positive in one patient with Microsporum gypseum. Trichophyton violaceum was isolated in 90% of positive cultures. The mean age was 4.6 years (range 1–11 years). All cases were classified clinically and subject to Wood light examination, microscopy, and culture. A prospective, cross‐sectional study was conducted over a 1‐year period. The goal of this study was to determine the demography, etiology, and clinical patterns of tinea capitis in South Africa. The hair involvement can be classified as endothrix, ectothrix, or favus, and the clinical appearance is variable.
