Radioimmunoassay of Minoxidil in Human Serum

Higher doses of dutasteride reduce scalp DHT more effectively than finasteride, but have diminishing returns after 3mg daily and may cause more side effects. Combining dutasteride with topical minoxidil can enhance results, but using both finasteride and dutasteride together is unnecessary.

A 20-year-old is considering switching from applying a Minoxidil 5%/Finasteride 0.1% solution twice daily to once daily due to cost and convenience. It is suggested that applying once a day before sleep should still be effective if done consistently.

Stopping and restarting minoxidil can cause significant hair shedding. The user is also using finasteride and microneedling to manage hair loss.

The user has been using finasteride for 8 years and started using minoxidil foam 5% twice daily with micro-needling since May 2025. They experienced significant shedding starting in July and are seeking information on how long the shedding will last and when to expect positive results.

The conversation discusses switching from topical to oral minoxidil, using oral minoxidil daily and topical minoxidil only on microneedling days. The user also mentions using finasteride and tretinoin but has not seen results after two months.

The user has stopped hair loss using topical finasteride, dutasteride, minoxidil 5%, and a GHK-Cu melatonin caffeine blend. They are considering switching to a more potent minoxidil, specifically Dualgen 15%, for better regrowth results.
