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 reported success with RU58841 and a 1mm derma roller for hair regrowth, noting significant improvement in hair density and reduced scalp visibility. They also mentioned using minoxidil and black castor oil in the past, with mixed results.

How Finasteride and Dutasteride help reduce hair loss by reducing the amount of DHT in scalp areas, as well as discussing factors such as sensitivity to DHT, 5α-reductase expression in different parts of the hair follicle, and scalp tension.
