In this animal study, zinc deficiency in mice was linked to disrupted hair cycles and impaired hair regrowth, which were reversed by zinc supplementation.

This study found that a decrease in estradiol levels in women is associated with increased hair shedding due to weakened anchoring of telogen hairs.

This cohort study using real-world data found no significant difference in the risk of developing prostate cancer between finasteride and dutasteride among patients with benign prostatic hyperplasia, despite previous suggestions that dutasteride might be more effective.

This study found that in healthy individuals, TGF-β1 levels in platelet-rich plasma are significantly higher when extracted using the buffy coat method compared to the pure method, with additional gender differences observed only in the buffy coat PRP.

In this study, applying water extracts of liquorice at a concentration of 2.5% to male rabbits led to the best rate of hair growth at 2.19 cm over 35 days, while a 5% concentration resulted in the greatest hair weight at 0.12 grams.

This study found that a combination of topical and oral treatment led to greater improvements in hair density, thickness, and anagen/telogen ratio in patients with androgenetic alopecia compared to topical treatment alone, with significant benefits observed over a 3-month period.

This study found that bulge-derived keratinocytes from human follicles were more resistant to differentiation compared to epidermal keratinocytes, possibly due to WIF-1 involvement.

This study demonstrated that topical oleuropein induced hair growth in mice by activating the Wnt10b/β-catenin signaling pathway and increasing expression of several growth-related genes in skin tissue.

This study found that baicalin activates Wnt/ß-catenin signaling in human dermal papilla cells, increasing alkaline phosphatase expression, growth factor expression, and promoting hair growth in mice.

In this study, 7-phloroeckol, derived from marine brown algae, was found to promote hair growth by increasing cell proliferation and hair shaft elongation in cultured human hair follicles.

This laboratory study found that nonanal, a plant scent compound, may stimulate growth factors and cell proliferation in human hair follicle dermal papilla cells, suggesting a cAMP-mediated mechanism.

This review discusses the increased incidence of hair loss and telogen effluvium among COVID-19 patients and evaluates existing evidence for regenerative treatments like PRP and HFSCs, finding limited published data.

This review explores the molecular controls of hair follicle cycling and highlights the challenge of developing effective treatments for common hair disorders without providing new clinical results.

In this study, 1'-S-1'-acetoxychavicol acetate (ACA) from Alpinia galanga showed potential in suppressing testosterone-induced hair loss by inhibiting Nox isozymes in a mouse model of androgenetic alopecia.

This review discusses the potential of therapeutic antibodies as an alternative treatment for androgenetic alopecia, highlighting the initial development stages and the need for further validation and optimization of targets like the prolactin receptor and Interleukin-6 receptor.

This study investigated the potential mechanisms of Curcuma aeruginosa in treating androgenetic alopecia and identified 66 bioactive compounds interacting with proteins involved in the disorder, suggesting its involvement in hormone response and specific signaling pathways.

In this study, Wnt-3a was found to play an important role in partially maintaining and expanding epithelial skin stem cells in vitro, suggesting potential for in vitro stem cell culture without feeder cells.

This study found that inhibiting AP-1 activity in mice modified tumor development, leading to transdifferentiation between squamous and sebaceous tumors, with molecular analysis suggesting AP-1's role in maintaining tumor cell identity.

This article explores the potential mechanisms by which polydeoxyribonucleotide (PDRN) could improve skin quality, slow aging, and enhance skin regeneration, but reports no new clinical findings.

This study identifies key transcriptomic features and a necessary dermal niche for eccrine gland development, advancing potential regenerative approaches for these vital skin appendages.

This study found that topical Rosmarinus officinalis leaf extract improved hair regrowth in mice and inhibited androgen-associated mechanisms involved in hair loss.

This review discusses the expanded understanding of WNT10B's role in various tissues and diseases over the past decade, emphasizing its genetic correlations and potential therapeutic implications, but reports no new clinical results.

This study found that overexpression of the lncRNA AC010789.1 in hair follicle stem cells may suppress androgen alopecia progression by modulating several molecular pathways, suggesting a potential new treatment strategy.

In this study, researchers found that the gene LRRC15 was overexpressed in dermal papilla cells from balding areas compared to non-balding areas in patients with androgenetic alopecia.

This study found that 1′S-1′-acetoxychavicol acetate from Alpinia galanga inhibits Nox isozymes and suppresses testosterone-induced hair loss in a mouse model of androgenetic alopecia.

This study found that gypenosides from Gynostemma pentaphyllum increased procollagen synthesis in vitro and reduced periorbital wrinkles by about 14% in a clinical trial with 24 women.

This review discusses the regulation and function of vitamin D and its receptor in skin cells, highlighting their roles in processes such as proliferation inhibition, differentiation, and innate immunity, but reports no new results.

This review examines the functions of vitamin D and its receptor in skin and explores how these are regulated, reporting no new clinical results.

This study found that back skin mesenchyme from mouse embryos can induce hair follicle formation even before dermal condensate formation, but R-spondin-1 alone or with a Bmp receptor inhibitor was not sufficient for hair follicle induction.

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.
