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.
The user does not respond well to minoxidil and is seeking an alternative to Tretinoin to upregulate sulfurtransferase activity for hair loss treatment. No specific alternative treatments were mentioned.
Liver problems may reduce the effectiveness of oral minoxidil due to impaired SULT1A1 enzyme activity, which is crucial for converting minoxidil to its active form. This reduction in enzyme function can significantly decrease the drug's effectiveness in promoting hair growth.
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.
Salicylic Acid shampoo may hinder topical minoxidil but not oral minoxidil, which works through the liver. The user plans to continue using oral minoxidil and is concerned about the shampoo's effect on it.
