In this study, oral administration of strawberry guava extract promoted hair growth in both mice and humans, with active components like adenosine, fructose, digalactosyldiacylglycerol, and pedunculagin contributing by enhancing skin blood flow and activating dermal papilla cells.

Minoxidil improves blood flow and vessel flexibility, potentially helping with vascular stiffness.

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.

Among in vitro and in vivo models, this study found that Miscanthus sinensis var. purpurascens flower extract may promote hair growth, potentially by modulating growth factor expressions and facilitating earlier hair follicle transitions in treated mice.

This study found that topical application of carpronium chloride led to arteriolar vasodilation and increased blood flow in rat mesenteric arterioles, without affecting systemic blood pressure.

This study suggests that Silybum marianum flower extract may promote hair growth and reduce hair loss by increasing proliferation and VEGF production in dermal papilla cells and suppressing cell senescence.

This study found that Cerasus serrulata extracts, when obtained through specific methods, demonstrate significant antioxidative and antibacterial properties, as well as potential anti-alopecia effects in a mouse model, potentially making them useful supplements for these purposes.

This study found that Nymphaea caerulea flower extract may improve scalp condition by reducing sebum production, inhibiting inflammation and microbial factors, and decreasing cortisol and vascular permeability.

This study suggests that women with alopecia have decreased microcirculation oscillations, which may imply neuroinflammation as a factor in the disease's pathogenesis.

In a study using a mouse model, Cerasus serrulata flower extracts significantly increased β-catenin and VEGF expression, promoting hair blackening and suggesting potential as a treatment for premature greying.

This review discusses the potential mechanisms by which intradermal botulinum toxin may affect androgenetic alopecia but notes that high-evidence clinical trials have yet to show conclusive results.

This study found that transplanting hair follicle bulge-derived stem cells in rats enhanced skin regeneration during expansion by differentiating into several skin-related cells and increasing the expression of growth factors.

This paper proposes a new hypothesis that androgenic hair loss may be caused by changes in scalp vasculature due to androgen effects, but reports no new experimental results.

This study found that MBN, an herbal extract fermented by Lactobacillus plantarum, promoted hair growth and increased related gene expression in C57BL/6 mice.

This review proposes an anatomy-based framework for understanding recipient site scalp necrosis in hair transplantation, emphasizing regional vascular vulnerability and surgical factors, but does not provide new clinical results.

This study found changes in the PGI2 pathway, especially in gene and protein expression, in diabetic mice, but did not observe PGI2-dependent vasomotor dysfunction.

The conclusion suggests a new treatment for infantile hemangiomas and a potential target for hair loss treatment.

This letter to the editor by Walter P. Unger discusses topics related to hair transplantation and reports no new research findings.

In this study, D-OCT imaging revealed distinct structural and vascular changes in patients with frontal fibrosing alopecia, highlighting the technique's potential for diagnosing and monitoring the condition's activity.

In this study, reflectance confocal microscopy was used to diagnose periorificial dermatitis, revealing specific skin changes such as hair follicle dilatation, increased vascular density, and inflammation, which help distinguish it from similar conditions.

This study found that intradermal injections of group B vitamins and cystin B6 complex improved scalp circulation, supported hair growth, and reduced hair loss in patients with diffuse alopecia.

This review explores the complex interactions between hair follicle stem cells and surrounding structures that are essential for understanding hair regeneration, reporting no new experimental results.

Stem cell treatment improved hair density in female hair loss patient.

A woman's nail separation was likely caused by poor blood flow, and a treatment for similar conditions might help.

This study outlines a technique for hair transplantation that maintains natural hair flow and density by mimicking natural hair direction and angle without accelerating hair loss in the recipient area.

This study elucidates a mechanism for male pattern baldness involving tension in scalp muscles that leads to reduced blood flow and hypoxia around hair follicles, proposing a multi-targeted therapeutic approach.

This article reviews the proposed mechanism of minoxidil in treating androgenetic alopecia, suggesting it may prolong the anagen phase by modulating cell growth factors and vascular activity, but reports no new results.

This research found that escin, when applied topically, enhances blood flow in human skin and promotes changes in endothelial cell signaling pathways, suggesting potential benefits for improving cutaneous microcirculation.

This study developed a dissolvable microneedle system loaded with nanozymes and minoxidil that enhanced hair regeneration in androgenetic alopecia mouse models by improving blood flow, reducing reactive oxygen species, and increasing cell proliferation compared to minoxidil alone.

This study identified neuropilin-1 as the receptor for FOL-026 and showed that it stimulates angiogenesis and cell growth, suggesting potential for vascular repair and enhanced angiogenesis therapies.
