Finasteride is effective in promoting hair growth and reversing hair miniaturization in men with androgenetic alopecia, with improvements seen in various studies over different durations. Some users report initial side effects like ball ache, which often resolve as the body adjusts.
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.
