The user is concerned about hair loss despite using oral finasteride, oral minoxidil, and topical minoxidil. They are seeking advice on additional blood tests to identify potential causes.
Biotin supplements are not effective for hair loss unless you are actually deficient, which is rare. Some users report improved hair quality with biotin, but there's no evidence supporting its use for hair loss in healthy individuals.
User shared 1-year progress on Fin 1 mg, switching to 0.4 mg Dut and oral 1.25 mg Min. Good results with Fin, biotin supplement, and biotin shampoo; trying Dut and oral Min for potential better results.
