frontal fibrosing alopecia androgenetic alopecia forehead epidermal corneocytes protein expression non-invasive monitoring FFA AGA

TLDR Protein profiling of forehead skin can help distinguish between frontal fibrosing alopecia and androgenetic alopecia.

The study investigated protein expression in forehead epidermal corneocytes to distinguish between frontal fibrosing alopecia (FFA) and androgenetic alopecia (AGA). Samples from 5 FFA patients, 5 AGA patients, and 12 controls revealed that FFA had 72 proteins significantly different from controls, with most showing lower expression, while AGA had only 3 proteins significantly different. This suggests FFA affects protein expression systemically, beyond the scalp. The findings support non-invasive monitoring of FFA through forehead epidermis protein profiling, indicating a potential for better diagnosis and treatment monitoring.

in Research/Science 40 upvotes 3 months ago

DUPA and retrograde alopecia may not be solely DHT-based, and a biopsy is crucial for accurate diagnosis and treatment. Treatments mentioned include dutasteride, oral minoxidil, pioglitazone, clobetasol, calcipotriol, ketoconazole, and doxycycline, depending on the specific condition.

community If You Have DUPA, PLEASE READ THIS: Everyone Should Be Scalp Biopsied

in Research 830 upvotes 9 months ago

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.
