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.
Hair loss theory suggests imbalance between Vitamin D Receptor (VDR) and Androgen Receptor (AR) activation. Proposed treatment includes upregulating VDR, downregulating AR, and improving mitochondrial health.
PP405 may damage hair follicles if used long-term, suggesting cycling might be necessary. Combining it with finasteride could help maintain hair growth.
A new hair loss protocol using FDA-approved topical treatments targets eight pathways, potentially improving results by 60-75% compared to the standard 40-50% from oral minoxidil and finasteride. The protocol includes minoxidil, finasteride, tacrolimus, cetirizine, bimatoprost, lithium gluconate, losartan, melatonin, NAC, caffeine, and tretinoin, with a monthly cost of $35-50 in Mexico and $80-150 in the US.
