Topical Finasteride doesn't directly reduce 5ar enzyme on scalp and has the same mechanism as oral, needing to go through the liver. Users debate the accuracy of this information and discuss various studies and experiences.
David Barreto shared that a London-based research group is conducting a 12-month trial for a new nutraceutical treatment for pattern hair loss, designed with Dr. Carlos Puig. The trial aims to provide robust data, with results expected in 1-2 years, potentially representing a significant advancement since finasteride’s introduction in 1997.
Minoxidil's effectiveness is limited by the need for sulfation and proper transport to hairfollicles, 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.
The treatment for androgenetic alopecia involves using finasteride and minoxidil with intense exercise and cold exposure to boost metabolism and reduce androgenic effects, potentially leading to hair regrowth. This approach may activate biological pathways for improved hair and overall health.
Microneedling may enhance hair regrowth by transferring stem cells to dormant follicles, improving the effects of minoxidil. Users discuss using microneedling with needle lengths around 1.5mm to stimulate hair growth.
