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.
This post and conversation are about the molecular mechanisms triggered by microneedling, specifically its effects on inflammation, tissue remodeling, epithelial proliferation, differentiation, and collagen synthesis. The discussion highlights the potential benefits of microneedling for hair loss treatment.
Tazarotene may be more effective than tretinoin when combined with topical minoxidil for hair loss due to its selective binding to RAR-beta and gamma, though it can cause irritation. Tazarotene's potency can lead to indirect inflammatory reactions despite potentially causing less irritation than tretinoin.
Tazarotene shows potential as a standalone treatment for hair regrowth by stimulating new hair follicle formation and promoting angiogenesis, similar to microneedling effects. It can be used topically without minoxidil, but users should start with a low concentration to avoid irritation.
RU58841 may pose cancer risks due to its antiandrogen properties and lack of long-term safety data. Using it is considered a high-risk experiment with unknown potential for harm.
