The conversation discusses how Tretinoin may improve the effectiveness of Minoxidil for treating hair loss by increasing the activity of certain enzymes in hair follicles. One user comments that this information is not new.
Hair loss and its potential treatments, such as minoxidil, finasteride, RU58841, dermarolling, and supplements. It discusses whether miniaturized follicles can be revived to grow again or must shed for new growth to appear.
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.
Salicylic acid in Nioxin shampoo may reduce minoxidil effectiveness by inhibiting sulfotransferase activity, potentially causing hair loss. Users suggest stopping salicylic acid use or trying alternative treatments like high-concentration tretinoin or medicated minoxidil/finasteride shampoos.
Minoxidil's effectiveness is limited by the need for sulfation and proper transport to hair follicles, with tretinoin potentially enhancing its effects by promoting enzyme activity and keratinocyte differentiation. Tretinoin may improve minoxidil's response by boosting the expression of necessary enzymes and transporters.
