Inflammation plays a key role in activating skin stem cells for hair growth and wound healing, but more research is needed to understand how it directs cell behavior.
Treatments for hair loss, including finasteride, dutasteride, minoxidil, ketoconazole, microneedling, and low level laser lighttherapy, which aim to reduce DHT production, increase cell absorption and blood flow, and stimulate epidermal stem cells. It also stresses the importance of patience when using these treatments.
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.
PP405 is a new hair loss treatment in phase 2 trials that may promote hair growth by increasing lactate production and activating hair follicle stem cells. It could potentially replace hormone-disrupting treatments like Minoxidil and finasteride.
Minoxidil's effectiveness is limited by the need for sulfation and proper transportto 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.
Topical dutasteride may be effective for hair loss by staying in the scalp and minimizing bloodstream absorption, potentially improving hair results and reducing side effects. The user seeks advice on its effectiveness.
