Dutasteride might be better for hairline due to varying levels of 5AR activity in scalps. Genetic tests can determine if finasteride is enough or if dutasteride is needed.
PP405 may damage hair follicles if used long-term, suggesting cycling might be necessary. Combining it with finasteride could help maintain hair growth.
Dutasteride may not be effective for everyone due to underlying issues, suggesting scalp biopsies for further diagnosis. Users discuss using higher doses of dutasteride, topical treatments, minoxidil, and pyrilutamide for hair loss management.
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.
