Distinguishing Histopathologic Features of Acantholytic Dermatoses and the Pattern of Acantholytic Hypergranulosis

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.

Pelage Pharmaceuticals' PP405 aims to treat hair loss by reactivating dormant hair follicle stem cells, showing promising results in early trials. The company plans to present their findings at the American Academy of Dermatology Annual Meeting in 2026.

PP405 shows promise in regenerating hair by activating dormant follicles. Other treatments like VDPHL01 and Breezula are also advancing, providing new hope for hair loss solutions.

Vitamin D deficiency can hinder hair recovery, and addressing it may help with hair loss. Hair loss may result from various issues like excess DHT, vitamin deficiency, or scalp inflammation.

A 27-year-old male with diffuse hair loss, including the donor area, did not respond to finasteride, dutasteride, or minoxidil. He suspects his hair loss may be linked to a mild connective tissue disorder, possibly affecting the structural support of hair follicles, rather than being purely hormonal.

The user diagnosed with DUPA tried treatments like dutasteride, finasteride, RU58841, and minoxidil without success and is considering a hair system. They hope for a future cure, possibly with PP405, and others suggest options like scalp biopsy and SMP.
