Who won’t respond to minoxidil? (Studies) Research/Science 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 / 1000+ 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 Will minoxidil not work if there’s too much DHT present in the scalp?
The user has been using topical finasteride and minoxidil for five months with little progress and is considering oral dutasteride to lower DHT levels, questioning if minoxidil is more effective with reduced DHT. They also use microneedling and tretinoin in their treatment routine.

User obsessed with hair loss prevention shares collection of treatments, including oral and topical finasteride, minoxidil, dermapen, and more. Others suggest adding RU58841, laser helmet, and PRP, while some advise dropping certain treatments for long-term manageability.
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.
