    TLDR A man with rare Lichen Planopilaris lost body hair, not scalp hair, and treatment stopped itching but didn't regrow hair.
    The document reports an unusual case of Lichen Planopilaris (LPP), a rare inflammatory disorder that typically affects the scalp, presenting as isolated body hair loss in a 38-year-old male. The patient experienced progressive hair loss on his limbs over two years, with intense itching preceding the alopecia. Previous treatments with antifungal agents were ineffective. Dermoscopic examination revealed perifollicular erythema and scaling, and a biopsy confirmed the diagnosis of LPP. The patient's symptoms of pruritus resolved after treatment with doxycycline and topical clobetasol, but hair regrowth was not observed. The patient chose not to continue treatment but was scheduled for follow-up every three months. This case highlights the need for clinical suspicion of LPP in patients with body hair loss, as the diagnosis can be challenging due to its rarity and the delay in proper diagnosis.

      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.

      Increased Malassezia and Cutibacterium in the scalp microbiome are linked to higher sebum production and inflammation in androgenetic alopecia (AGA). Treatments include ciclopirox shampoo, benzoyl peroxide shampoo, clobetasol propionate, calcipotriol, minoxidil, finasteride, and dutasteride.

      Excess sebum rich in cholesterol and triglycerides can lead to hair loss through inflammation, with treatments like Ciclopirox shampoo, Benzoyl Peroxide shampoo, and Clindamycin gel recommended for managing conditions like seborrheic dermatitis and folliculitis. Pioglitazone is suggested for Lichen Planopilaris, while Omega-3s and reducing processed foods may improve sebum quality, though genetic factors play a significant role.

      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.
