Who won’t respond to minoxidil? (Studies) 3/4/2026
Minoxidil's effectiveness varies due to differences in sulfotransferase enzyme levels in the scalp, affecting people with conditions like ASD, liver disease, and androgenic alopecia. Treatments like topical tretinoin, microneedling, and using minoxidil sulfate instead of regular minoxidil can improve results for those with low enzyme levels.

5 / 5 resultscommunity I literally can’t find any evidence of sulfotransferase being upregulated by microneedling or retinoids like tretinoin
Microneedling and tretinoin may enhance minoxidil absorption for hair loss, but evidence on their effectiveness is limited. Iron supplements and broccoli sprouts are suggested for enzyme activation, but their impact on hair is unclear.
community Hair has only gotten worse ~10 months on minoxidil.
The user experienced worsening hair loss despite using finasteride and topical minoxidil, and is considering switching to dutasteride and oral minoxidil. They also tried microneedling and tretinoin with minoxidil, and are exploring Sulfogenz topical minoxidil.
community M21. Topical Fin + Min 5 weeks progress. Is there any hope?
A 21-year-old is using a topical solution with minoxidil and finasteride for hair loss, along with supplements and specific shampoos, and is considering switching to oral treatments if no progress is seen in a few months. They are concerned about diffuse thinning and potential future hair transplants, and are exploring additional treatments like microneedling and tretinoin.
community Is microneedling + minoxidil better than oral minoxidil
Oral minoxidil is considered more effective for hair regrowth than topical minoxidil, but it carries higher risks. Combining microneedling with topical minoxidil can enhance absorption, but oral minoxidil with microneedling shows significant results.
community 26, seeing some incredible results 3,5 months in with topical minoxidil and derma rolling 1x a week
A user experienced significant hair regrowth after 3.5 months using topical minoxidil and weekly derma rolling. Others discussed enhancing results with finasteride, ketoconazole shampoo, and microneedling.
