Dutasteride may not effectively stop scalp hair loss and can cause thinning of facial and body hair, including eyebrows. Users suggest considering other causes like autoimmune conditions or vitamin deficiencies and exploring treatments like finasteride or minoxidil.
Finasteride can impact neurosteroids, potentially causing depression and other side effects in some users. Despite these concerns, many continue using it for hair loss, with some switching to topical applications to mitigate side effects.
Microneedling alone may not be effective for hair regrowth, though it can improve skin and reduce scars. Minoxidil caused heart palpitations for one user, leading them to stop its use.
The conversation discusses using very low dose topical finasteride to achieve specific serum DHT reduction percentages. It concludes that finasteride dosage increases linearly between 5-30% DHT reduction but requires exponential increases for reductions up to 70%.
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.
