This study observed that PCE-DP may improve skin pigmentation by increasing epidermal turnover and inhibiting melanin uptake and inflammation in human epidermal keratinocytes.

This report details the development of a PSR™ Terminalia extract with antioxidant and anti-aging potential, highlighting its rich composition in phenolic acids, polysaccharides, and organic acids, without new clinical results.

This study found that human placental extract promoted hair growth and influenced cellular pathways in vitro and rat models, suggesting potential for future hair loss treatments.

In this study, nanocapsule-based preparations containing hinokitiol promoted hair growth in mice comparably to Minoxidil solution, as indicated by photographic and histological analysis.

This study found that quercitrin, a natural compound, enhances Wnt/β-catenin signaling and may help mitigate synapse loss and memory impairment in Alzheimer's models.

The combination of a plant extract and a peptide can increase hair pigmentation and may reverse greying.

This study found that PNU 157706 is a highly potent inhibitor of human 5α-reductase enzymes, showing a stronger and longer-lasting antiprostatic effect in rats compared to finasteride.

This review discusses the potential benefits of flavonoid-containing botanicals, such as Panax ginseng, in reducing hair loss and promoting hair growth, but reports no new experimental results.

Procyanidins and phosphatidic acids help promote hair growth.

This study found that an aqueous extract of Phyllanthus emblica, primarily containing gallic acid, can activate hair growth gene expression and is effectively delivered to hair follicles using transfersomes.

This study found that compound 2 from Polygonum multiflorum increased dermal papilla cell proliferation and vibrissa follicle hair-fiber length more effectively than minoxidil in vitro, suggesting potential for alopecia treatment.

In this study, Panax ginseng extract and its ginsenosides were found to stimulate the proliferation of hair-related cells and promote the transition from the telogen to the anagen phase, enhancing hair-shaft growth by suppressing BMP4 expression in human dermal papilla cells.

This study suggests that CGE may enhance hair growth by activating β-catenin signaling pathways in human hair dermal papilla cells and promoting the anagen growth phase in mice.

This preclinical study observed that a nanoencapsulated ingredient complex, AcPi, may prevent hair follicle aging and hair loss by reducing oxidative stress, enhancing mitochondrial activity and WNT/β-catenin signaling, and controlling androgenic metabolism when tested on human scalp cultures.

In this study involving ICR mice, researchers found that Korean red pine bark extract improved cognitive functions impaired by TMT through mechanisms like antioxidant system protection, cholinergic and synaptic support, mitochondrial regulation, and reduction of neuro-inflammation and apoptosis.

This study found that Cynatine HNS significantly improved hair and nail health in women after 90 days compared to placebo.

In this study, researchers reviewed non-pharmacological treatments for androgenetic alopecia, finding that substances like caffeine, rosemary oil, and saw palmetto may stimulate hair growth or inhibit dihydrotestosterone. They emphasize the need for multicenter clinical trials to further assess these natural products' efficacy in clinical practice.

This study found that a three-month regimen of leucoselect phytosome, a grape seed extract complex, was well tolerated and significantly reduced bronchial proliferation markers in heavy active and former smokers.

This study found that combining prodigiosin and essential oil from Thuja orientalis leaves showed a synergistic effect against the 3rd larva stage of Cx. pipiens, significantly reducing acetylcholine esterase activity and altering midgut pH, compared to untreated larvae.

In this study, researchers used an integrated in silico approach to demonstrate that Polygonum multiflorum combats androgenetic alopecia via anthraquinone emodin, which targets PI3K catalytic subunits differently from traditional antiandrogenic treatments, showing potential as a novel therapeutic strategy.

This study identified a thiazolidine dione derivative as a potential inhibitor of 15-PGDH that may enhance prostaglandin activity in hair follicles, suggesting its use to support hair regrowth treatments.

This study found that Paeonia lactiflora and Poria cocos extracts promoted hair regrowth in a mouse model of androgenetic alopecia, with similar effects observed to normal controls.

This study found that 0.7% apple procyanidin oligomers applied externally for six months significantly increased hair growth in men with male pattern baldness compared to placebo, with no observed adverse effects.

This study found that pectin lyase-modified red ginseng extract may promote hair growth by enhancing antioxidant and anti-inflammatory activities, along with inhibiting testosterone-induced 5-alpha-reductase in human hair dermal papilla cells.

This study found that 4-(4-Phenoxybenzoyl)benzoic acid derivatives may act as antioxidants by scavenging certain reactive oxygen species but exhibit prooxidant behavior under specific conditions.

This study found that applying an ethanol extract of Prasiola japonica improved hair regrowth, length, and follicular density in testosterone-induced hair loss conditions in mice, while also promoting dermal papilla cell proliferation and reducing dihydrotestosterone production, though effects were less pronounced than those of minoxidil.

In this study, petroleum ether extracts of Phyllanthus niruri promoted hair regrowth in testosterone-induced alopecia in rats by inhibiting the 5α-reductase enzyme.

This study found that genipin-based pigments, accelerated by riboflavin and blue-light photocatalysis, achieved commercial-level hair dye results with enhanced gloss and excellent color retention while reducing cuticle disruption, offering a potentially safer and faster alternative to traditional hair coloration methods.

This study demonstrated that Periplaneta americana extract significantly promoted hair regeneration in depilated mice by enhancing superoxide dismutase activity, upregulating vascular endothelial growth factor, modulating the FOXO/PI3K/AKT pathway, and restoring skin microbiome balance, suggesting its potential as a novel therapeutic candidate for alopecia.
