In this study, researchers found that sweet potato shochu oil promotes hair growth in both human follicle dermal papilla cells and C3H mice. The oil contains components like ethyl palmitate, ethyl linoleate, and ethyl α-linolenate, which were key contributors to its hair growth-inducing effects.

This review discusses the molecular mechanisms of androgen action in human hair follicles and reports no new findings; the authors emphasize the need for further research to improve treatments for hair disorders.

This study found that bee venom accelerated the transition from the telogen to anagen phase in mice, increasing hair growth by day 14, and suggested that bee venom may enhance adipose-derived stem cell activity by upregulating growth factor secretion.

In this in vitro study, niacinamide was found not to stimulate VEGF synthesis across a wide range of doses.

This study found that Glehnia littoralis and Andrographis paniculata may support hair growth by protecting against oxidative stress and increasing VEGF and Wnt/β-catenin signaling in human hair follicle dermal papilla cells, with enhanced effects when combined.

This study found that topical application of Sinsun-yukza-hwan extract significantly increased hair density and thickness in a mouse alopecia model and enhanced expression of growth-related genes.

This study found that dermal papilla-like tissues derived from canine adipose stem cells promoted new hair follicle formation and increased vascularization in athymic nude mice.

This study found that keratin-gelatin composite films effectively promoted early wound healing and full-thickness skin graft acceptance in dogs, outperforming bFGF-gelatin films.

This study outlines a hair regrowth treatment targeting hair follicle stem cells, 5-alpha reductase pathway, and microinflammation using PDGF and VEGF, but reports no clinical results.

This study found that phosphorus and nitrogen deprivation increased root hair length in Brassica carinata and induced the expression of certain P-responsive genes, such as LRR and PRP.

This study found that nearly half of the tinea capitis patients at a Surabaya hospital had cat contact, with the most common symptoms being crust and hair loss.

In this study, women with polycystic ovarian syndrome were found to have significantly higher blood levels of DHEA, IL-6, and TNF-α compared to healthy controls.

This study found that epidermal VEGF is crucial for maintaining skin barrier function in mice and may help explain psoriasis development following skin trauma due to its effects on angiogenesis and hyperplasia.

Minoxidil boosts hair growth by targeting adenosine and possibly sulfonylurea receptor 2B.

In this study, immobilized VEGF selectively captured endothelial cells under various shear stresses, suggesting its potential for promoting endothelialization in vascular grafts or implanted tissues.

This article discusses the challenges and possible solutions in hair restoration surgery, focusing on donor hair availability, hair survival, and concealing surgical evidence, and reports no new clinical results.

This study found that estrogen affected cell behaviors differently in a scratch-wound assay, increasing VEGF secretion in follicular dermal papilla cells but decreasing it in wounded dermal sheath cells.

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 suggests that sinapic acid may promote hair growth in human hair follicle dermal papilla cells by activating specific signaling pathways and inducing the expression of growth factors.

This study suggests that Ecklonia cava, particularly its component dioxinodehydroeckol, may promote hair growth by enhancing dermal papilla and outer root sheath cell activity in culture and mice models.

This study found that cow placenta extract increased hair follicle size and hair length in mice but was less effective than minoxidil, suggesting potential with further refinement.

This study found that ethanol extracts of Allium tuberosum Rottler ex Spreng significantly promoted hair growth in mice, possibly by increasing IGF-1 expression.

This study found that brain-derived nerve factor protein expression was significantly increased in balding scalp samples from men with androgenetic alopecia, suggesting it may play a role in hair follicle regulation.

This study found no evidence that HDGF expression transforms melanocytes into tumors in a mouse model, although it may play a role in cell differentiation and tumor progression.

This study demonstrated that α-phellandrene promotes dermal papilla cell proliferation through a cAMP-mediated pathway and upregulates VEGF expression, suggesting its potential use in hair loss prevention.

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 study found that intramuscular injections of a PRP-derivative in healthy beagle dogs did not result in statistically significant changes in lumbar muscle tissue or IGF-1 blood concentration, suggesting the treatment may be safe at therapeutic doses.

This study suggests that IGF-1, a component of human placenta hydrolysate, promotes hair growth by increasing the number and size of hair follicles in mice.

This study found that a hair tonic containing 10% mesenchymal stem cell secretome significantly increased hair density in volunteers with alopecia after eight weeks, suggesting its potential as an effective treatment option for hair growth stimulation.

In a murine model of androgenetic alopecia, this study found that the newly designed IGF-1 biomimetic peptide Ac-GFFY-IGF led to faster and superior hair regrowth compared to minoxidil, suggesting potential for improved human therapies.
