Newly Observed Interference of Oral Biotin with the Free Testosterone Assay in a Woman with Postmenopausal Virilization

A 26-year-old male experienced significant hair regrowth using a 4-in-1 topical treatment from Hims, which includes minoxidil, finasteride, ketoconazole, and biotin, over four months. The user reported increased body and beard hair, skin changes, and no negative sexual side effects, while others noted the rapid and impressive results as atypical.

The conversation is about concerns over biotin causing acne when taken with finasteride and minoxidil for hair loss. One user suggests biotin is unnecessary, while another shares that it didn't cause acne for them.

The user has been using oral minoxidil (5mg), finasteride (1mg), and biotin for 4 months with minimal progress in hair regrowth. Other users suggest patience, considering alternative treatments, and note that biotin may not significantly contribute unless there's a deficiency.

The user experienced significant hair improvement after switching from topical to oral treatments, using finasteride, minoxidil, and biotin. They reported no major side effects, except for slightly thicker hair on their hands.

A 25-year-old male shared his 3-month progress using oral minoxidil, finasteride, and biotin for hair growth, reporting positive results and minimal side effects, such as slightly reduced libido. He plans to continue treatment and possibly add microneedling, with hopes of further improvement and potential hair transplant if needed.

A user was diagnosed with male pattern baldness and prescribed biotin, vitamin D, a hair serum, fluocinolone shampoo, and a gel with minoxidil and finasteride. Other users suggest focusing on oral finasteride and minoxidil, questioning the necessity of the other treatments.
