    Area of Science:

    • Dermatopathology
    • Trichology

    Background:

    • Scalp biopsies are essential for diagnosing hair loss.
    • Understanding normal hair patterns and histology is key.

    Purpose of the Study:

    • To outline the diagnostic utility of scalp biopsies.
    • To identify common scalp conditions through histologic examination.

    Main Methods:

    • Excision or punch biopsy of scalp tissue, including subcutaneous fat.
    • Histologic evaluation of biopsy specimens.

    Main Results:

    • Biopsies allow identification of conditions such as common baldness, trichotillomania, alopecia areata, discoid lupus erythematosus, lichen planopilaris, tinea capitis, and follicular mucinosis.
    • Histologic features correlate with specific diagnoses.

    Conclusions:

    • Accurate diagnosis of hair loss through scalp biopsy is important.
    • While often psychologic, hair loss diagnosis has significant clinical implications.
