    August 2001 in “ International Journal of Dermatology ”
    Virendra Sehgal, Pramila Bajaj
    TLDR A 20-year-old had hair loss and skin issues from lichen planopilaris starting at age 10.
    The document described a case study of a 20-year-old laborer who began experiencing symptoms of lichen planopilaris (LPP) at age 10, characterized by progressive hair loss on the scalp, pruritis, and slate-blue eruptions. The condition led to complete hair loss on the scalp, resembling male-pattern baldness, with grayish-blue follicular papules and perifollicular erythema. Histological examination of the scalp lesions showed uniform epidermal atrophy, basal cell vacuolization, and dilated hair follicles filled with keratin plugs, alongside dermal fibrosis and lympho-histiocytic infiltrate. The study highlighted the absence of hair follicles and sebaceous glands, while arrectores pilorum and sweat glands were preserved.

      Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.

      Men with hair loss might have lichen planopilaris (LPP), which can mimic androgenetic alopecia, leading to misdiagnosis and ineffective treatment with finasteride or dutasteride. Proper diagnosis, including biopsies, is crucial to distinguish between androgenetic alopecia and conditions like LPP.
