Linear Lichen Planus Pigmentosus of the Face with Histological Findings of Lichen Planopilaris: An Uncommon Variant of Lichen Planus

Lichen Planopilaris (LPP) is an autoimmune condition causing permanent hair loss and fibrosis, often misdiagnosed. Treatments include pioglitazone, topical corticosteroids, anti-inflammatory medication, and Jak inhibitors.

Prostaglandin balance affects hair loss, particularly in conditions like Lichen Planopilaris, where an imbalance can lead to hair follicle damage. Treatments mentioned include prostaglandin analogs and Pioglitazone HCL, with a focus on maintaining prostaglandin equilibrium for potential hair regrowth.

The user is experiencing diffuse thinning and inflammation despite using 2.5mg dutasteride daily, ciclopirox, and ketoconazole shampoos. They are considering treatments like hydroxychloroquine and JAK inhibitors due to suspected scarring alopecia and have faced challenges in obtaining a scalp biopsy.

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.

Pelage is developing a topical hair follicle stem cell therapy, PP405, for non-scarring alopecias like androgenetic alopecia, with Phase III trials planned and a potential market launch by 2027. The treatment may not require continuous use after initial regrowth.

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.
