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 was prescribed 5mg of Finasteride daily for hair loss, which is a higher dose typically used for prostate issues. Many suggest using a pill cutter to reduce the dose to 1mg or less per day, as it is more cost-effective and equally effective for hair loss.
