Sildenafil (Viagra) shows potential for hair growth by enhancing dermal papilla cell proliferation and stimulating perifollicular vessel formation. Users discuss the possibility of using Cialis (tadalafil) similarly, noting its benefits and side effects.
Transplanting mice skin to humans is not feasible due to immune rejection, but some suggest genetic modification or immune suppression could make it possible. Xenograft hair transplants are discouraged.
Human pluripotent stem cells have been used to create hair and skin, potentially offering a new solution for baldness. A user also mentioned starting finasteride but experiencing unexpected hair thinning.
MCL-1 protein may help maintain hair follicles in the growth phase and prevent miniaturization. There is interest in experimental treatments like exosomes, peptides, or stem cell serums to upregulate MCL-1 for hair loss, especially for those not using minoxidil or finasteride.
Hair regrowth treatments are effective in mice but not yet available for humans. The discussion humorously highlights frustration over this disparity and mentions a project to genetically modify elephants to resemble mammoths.
