Soluble and Insoluble Collagen and Elastin in the Rat Hair Cycle

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.

The conversation discusses the use of oral versus topical minoxidil for hairline recession, with concerns about collagen synthesis inhibition. Oral minoxidil may affect collagen production more broadly, while topical minoxidil's effects are localized but may cause skin issues.

Sodium dodecyl sulfate, oleic acid, and palmitoleic acid may promote hair growth, but their safety and effectiveness for humans are uncertain. Users consider trying these treatments cautiously, exploring alternatives like ostrich oil and microneedling.

Collagen supplements, often combined with L-cysteine, are reported to thicken hair but are not sufficient for preventing hair loss. Users also mention using other treatments like minoxidil, Nizoral, and dermarolling for hair regrowth.

Collagen peptides may help with hair growth, but results vary; some users noticed less hair fall and improved nail strength. Minoxidil is suggested for regaining hair thickness lost from accutane.

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.
