Some nutrients and antioxidants may improve skin and hair health, but more research is needed to confirm these benefits.

The document lists various dermatology topics, treatments, and diagnostic methods.

In this study, procyanidin B-2 and C-1 were found to promote hair growth by selectively inhibiting protein kinase C, supporting their potential use for hair-growing activity.

This study found that polyacetylene compounds in Panax ginseng extracts may inhibit neurotrophin receptor binding, suggesting potential therapeutic benefits for alopecia and other hair growth disorders.

This study reported that Cacumen Platycladi extract significantly reduced hair loss and increased hair density in a 12-week clinical trial, suggesting it may be a safe and effective natural treatment.

This study found that Crataegus pinnatifida extract promoted hair growth in mice by inducing the anagen phase, potentially through activating signaling pathways that enhance cell survival.

This study found that a 4:1 combination of Rhynchosia nulubilis and Polygonum multiflorum extracts significantly promoted the proliferation of human dermal papilla cells and alleviated testosterone-induced cytotoxicity, suggesting potential for treating hair loss and related disorders through a synergistic approach.

This study found no significant difference in anagen rate improvement between the CYP-based dietary supplement and placebo in women over 60 with telogen effluvium, possibly due to variable patient inclusion related to hair growth seasonality.

This study found that total glucosides of paeony (TGP) reduced hair loss and inflammation in alopecia areata mice by inhibiting cellular pyroptosis.

In this study, researchers developed a polyphenol–amino acid nanozyme capable of controlled hydrogen peroxide delivery, which effectively activated hair follicles via oxidative stress in a mouse model, suggesting a potential non-pharmacological treatment for alopecia.

This study found that Pinus massoniana needles extract may promote hair regrowth in a mouse model of androgenetic alopecia, potentially by reducing oxidative stress and affecting immune, metabolic, and apoptosis-related pathways.

In this study, a new formulation of human placental extract showed antioxidant and neurite outgrowth activities, significantly reduced hair graying in mice, and alleviated neuropathy symptoms, suggesting potential therapeutic benefits.

This study demonstrates that pea sprout extract promotes hair growth by activating specific signaling pathways and providing antioxidant and anti-inflammatory effects, suggesting its potential as a natural alopecia treatment.

This study identified 43 compounds in Platycladi Cacumen, including flavonoids, and found significant chemical variation in flavonoid content across different regions and processed products.

This study observed that Poria cocos polysaccharides and finasteride both reduced inflammation in chronic nonbacterial prostatitis in rats, but only Poria cocos polysaccharides reversed related changes in the gut microbiota.

This study developed a reliable UHPLC-MS/MS method to measure flavonoids from Pinus massoniana needles in rat plasma for pharmacokinetics, aiding further research on their potential use in external preparations to prevent hair loss.

This study found that dietary pyridoxine increased hair follicle density in Rex rabbits by activating PI3K/Akt, Wnt, and Notch signaling pathways, which may promote hair growth and delay telogen onset.

This study found that Ecklonia cava polyphenols increased human dermal papilla cell proliferation and extended hair shaft length in vitro and ex vivo, suggesting potential as a therapeutic candidate for hair loss.

This study found that extracts from Geranium pyrenaicum show promising antioxidant, enzyme inhibitory, and antiviral activities, particularly the methanolic extract's antiviral activity against HSV-1.

This study investigated the potential of nutmeg-derived phytochemicals as anti-alopecia agents using molecular docking and simulations, finding that geranylgeraniol exhibited significant binding stability and potential efficacy against androgenetic alopecia comparable to finasteride and superior to minoxidil.

In this study, PP-PTKL exhibited antioxidant, anti-inflammatory, and pro-melanogenic effects in laboratory settings, suggesting its potential role in preventing or treating hair greying. Further animal and human studies are needed to verify these findings.

This study found that procyanidin B-2 may promote hair growth by reducing expression and inhibiting translocation of PKC isozymes in murine hair epithelial cells.

In this study, Cyperus rotundus essential oil was found to have significantly better depigmenting effects than hydroquinone for treating axillary hyperpigmentation, with additional benefits in reducing inflammation and hair growth, making it a cost-effective and safe treatment option.

This study suggests that Platycarya strobilacea extract promotes hair growth in mice by enhancing stem cell factor expression, reducing mast cell numbers, and increasing cytokines associated with hair growth.

In this study, topical application of Korean maritime pine bark extract at 2% concentration significantly promoted hair growth in mice, suggesting its potential use for hair loss prevention or treatment.

This study found that Cacumen Platycladi volatile oil promotes dermal papilla cell proliferation and enhances hair growth in mice, outperforming minoxidil and showing no obvious cytotoxic effects.

In laboratory and artificial skin model experiments, this study found that plant-derived PDRN from Korean ginseng effectively promoted skin cell regeneration and strengthened the skin barrier, suggesting a sustainable alternative to animal-derived PDRN.

This study investigated the mechanisms of Platycladi Cacumen in treating androgenetic alopecia, identifying potential key components and targets but found no specific targets or regulatory mechanisms.
