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.
Dutasteride may cause chronic infertility by reducing semen volume and motility, with concerns about irreversible prostate fibrosis. Users consider switching to finasteride or using treatments like minoxidil and microneedling, weighing hair preservation against fertility.
