Excessive scalp sebum, worsened by DHT, can lead to inflammation and hair loss, with clascoterone mentioned as a treatment. Diet changes seem ineffective for scalp sebum, and treatments like minoxidil and finasteride are suggested.
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.
