Finasteride and dutasteride can improve skin texture and reduce acne by lowering DHT but do not reverse aging. They may enhance skin and hair health for some, but can also cause side effects like dry skin and sexual dysfunction.
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.
The DHT itch is linked to hair loss and persists despite finasteride use; switching to dutasteride helped alleviate the itch and promoted regrowth. Some users suggest seborrheic dermatitis as a cause and recommend treatments like medicated shampoos, vitamin D, and minoxidil.
Topical Finasteride doesn't directly reduce 5ar enzyme on scalp and has the same mechanism as oral, needing to go through the liver. Users debate the accuracy of this information and discuss various studies and experiences.
