A gel of keratin microspheres promotes hair follicle growth, showing similar effectiveness to minoxidil in mice. The treatment activates hair growth pathways and reduces inflammation, with potential applications in drug delivery for hair-related disorders.
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.
PP405 is a new topical treatment for hair loss, showing promise in trials but still requires finasteride for maintenance. There is skepticism about its effectiveness and safety, with concerns about needing finasteride to maintain results.
There have been no new effective hair loss treatments since finasteride, despite technological advancements. Current treatments include finasteride, minoxidil, and RU58841, with ongoing challenges and potential future solutions in research.
