The efficacy of low doses of finasteride to reduce scalp DHT, and whether studies showing a 61% reduction are reflected in actual results. Replies discussed hair growth as an unintended consequence of minoxidil and finasteride use, as well as self-selective bias, potential side effects, and that studies measure effectiveness by hair count changes rather than DHT inhibition.
Dutasteride and finasteride may temporarily affect semen quality but are unlikely to cause permanent infertility. The Kim et al. study is criticized for poor methodology, and many prefer hair retention over potential fertility concerns, using treatments like dutasteride, finasteride, and minoxidil.
A user shared their positive experience with a 4-in-1 topical solution containing finasteride, minoxidil, ketoconazole, and biotin, along with weekly microneedling using a 1.2mm dermastamp. The user reported no noticeable side effects and mentioned that the biotin likely doesn't contribute to hair growth.
Switching from finasteride to dutasteride and back to finasteride led to gynecomastia and fatigue, likely due to hormonal imbalances. Suggested treatments include Tamoxifen, Raloxifene, or low-dose Anastrozole, with a recommendation to test testosterone and estradiol levels.
A user shared their positive 3-month experience using finasteride, minoxidil, and vitamin D to treat hair loss, noting significant regrowth and minimal shedding. They also discussed potential side effects and the low likelihood of experiencing them, while being open to answering further questions.
