Transverse scalp sections are better for diagnosing non-scarring hair loss, while vertical sections are better for a specific scarring hair loss called lichen planopilaris.
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.
A user lost 60% hair density in 4 months, started finasteride and microneedling, and has greasy, flaky, yellowish scalp. They are awaiting biopsy results, and another user suggested trying ketoconazole shampoo.
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.
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.
Dutasteride may not be effective for everyone due to underlying issues, suggesting scalp biopsies for further diagnosis. Users discuss using higher doses of dutasteride, topical treatments, minoxidil, and pyrilutamide for hair loss management.
