    TLDR Lichen Planopilaris in teens is rare, often misdiagnosed, and responds well to steroids.
    The study examined four pediatric cases of Lichen Planopilaris (LPP) in patients aged 13 to 16 years, highlighting its rarity and potential for misdiagnosis as alopecia areata. Common findings included perifollicular scale, scarring, and histopathologic evidence of perifollicular interface and fibrosis. Treatments with topical or intralesional steroids and minocycline were used, with good long-term responses in two patients. The study emphasized the importance of biopsying active inflammation for accurate diagnosis and supported corticosteroids as a first-line treatment.

      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.

      The DHT itch is linked to hair loss and persists despite finasteride use; switching to dutasteride helped alleviate the itch and promoted regrowth. Some users suggest seborrheic dermatitis as a cause and recommend treatments like medicated shampoos, vitamin D, and minoxidil.
