Quercitrin Stimulates Hair Growth with Enhanced Expression of Growth Factors via Activation of MAPK/CREB Signaling Pathway

This study found that topical resveratrol significantly promotes hair growth in mice and may protect human dermal papilla cells from oxidative damage, suggesting its potential as a treatment for hair loss.

In this experimental study, the researchers observed that Platycladus orientalis leaf extract promoted hair growth by enhancing dermal papilla cell proliferation and increasing growth factor expression, particularly through ACK1 activation and modulation of Wnt/β-catenin signaling pathways in cultured human cells and a 12-week topical application.

In this study, researchers found that topical treatment with adenosine improved hair growth and thickness by significantly increasing hair density and thickness after four months in vivo, with results comparable to minoxidil, potentially due to adenosine's anti-androgenic effects.

This paper reviews extraction methods for obtaining polysaccharides from brown macroalgae like Sargassum, highlighting their antiviral, antimicrobial, and antitumoral bioactivities in both in vivo and in vitro studies, while also discussing challenges in research and commercialization of Sargassum-based products.

This study suggests that guava leaf extract may inhibit hair loss by downregulating genes involved in androgen synthesis, potentially offering a natural alternative for treating androgenetic alopecia.
