This study confirms that finasteride inhibits the conversion of testosterone to dihydrotestosterone in human dermal fibroblasts, suggesting potential therapeutic use for androgen-related skin disorders.
Hair regrowth on wounded and bald skin may be possible by activating the sonic hedgehog gene, leading to hair regrowth in mice. The findings are promising but may not directly apply to humans.
The conversation discusses the lack of in vivo studies on the effects of minoxidil and finasteride on human collagen and elastin after a year of use. It highlights the potential benefits of such research for understanding side effects and improving sales, despite challenges like cost and competition.
Oral minoxidil may cause dry skin and dark eye bags but doesn't significantly age the skin. Topical minoxidil is toxic to cats, and some users prefer finasteride.
Oral minoxidil is effective for hair loss and unlikely to significantly affect collagen synthesis, making it a safe option without causing premature skin aging. Users report positive hair regrowth without noticeable skin aging.
Finasteride and dutasteride can improve skin texture and reduce acne by lowering DHT but do not reverse aging. They may enhance skin and hair health for some, but can also cause side effects like dry skin and sexual dysfunction.
Can long-term use of Fluocinolone affect the health of hair follicles?There is no long-term human trial measuring what topical fluocinolone does to hair follicles; what is documented is the label's warning about skin atrophy with prolonged use, plus a 2007 mouse study suggesting hair-follicle bulge stem cells do not repair steroid-induced atrophy.
What is GHK-Cu and why is it said to be a "miracle" for hair?GHK-Cu is a copper peptide studied mainly for wound healing and skin repair; for hair loss the evidence stops at cell-culture and animal work, and no published human trial has tested it for androgenetic alopecia.
Can latanoprost be safely applied to the scalp, or is it only for eyelashes?Latanoprost is not approved for use on the scalp and its safety there has not been established: the only human scalp evidence is one 24-week pilot trial in 16 men, and clinicians flag irritation, skin darkening and unknown absorption over a large area as open risks.
