In this study, EREG promoted hair growth by activating specific receptors in cell and animal models, indicating it may be a potential treatment for hair loss.

This study found that UV stabilizers must diffuse uniformly and in high uptake levels throughout hair fibers during humidification cycles to effectively prevent photo-oxidative degradation.

This study found that human mesenchymal stem cell-derived extracellular vesicles promote the proliferation and migration of hair follicle cells and increase hair shaft elongation in cultured human hair follicles.

This article reviews in-vitro and cell-free methods for assessing the efficacy of herbal ingredients in cosmetic formulations for skin health and hair growth, but it reports no new clinical results.

This study found histopathological evidence of hypertrophy in nerve endings that may explain the cutaneous neurosensory symptoms in some long COVID-19 patients.

This upcoming review will investigate the role of hair follicle fibroblasts in androgenetic alopecia, focusing on their interactions with androgens and impact on cellular signaling and fibrosis.

This review highlights the potential of nanotechnology for hair follicle regeneration, focusing on strategies such as hair cycle modulation, progenitor cell stimulation, and wound-induced hair neogenesis, while also discussing regulatory challenges that may affect the development of these innovative approaches.

This study found that transgenic mice expressing a mutant E1a oncoprotein in their skin had disturbed hair follicle maturation but did not show increased tumor development or proliferation.

This research found that Dlx3 plays a central role in hair formation and regeneration, with its absence leading to alopecia through disrupted differentiation and signaling pathways.

This study found that human peptidylarginine deiminase type III is the predominant isoform in hair follicles and may modulate structural proteins during hair and hair follicle formation.

This study demonstrates that SDF-1/CXCL12 and CXCR4 signaling play a crucial role in directing the migration and positioning of melanoblasts in mouse hair follicle formation.

Keratin patterns in hair follicles help understand hair growth and potential hair and nail disorders.

This research found that activating a KrasG12D mutation in mice led to skin thickening, papillomas, and hair growth issues, suggesting that even rare KRAS mutations can mimic human RAS/MAPK syndrome symptoms.

This study found that in bovine skin, leptin and its receptor are expressed in the epidermis and hair follicles, suggesting a role in epidermis growth and hair follicle cycling through paracrine and autocrine mechanisms.

This study successfully developed 3D hair follicle organoids from neonatal mouse epidermal and dermal cells, showing structural and molecular resemblance to native anagen hair follicles.

In this review, researchers reported that pyroptosis, a type of inflammatory cell death linked to inflammasome activity, is a key factor in the pathogenesis of alopecia areata and may present new therapeutic opportunities, though most treatments are still in early research stages.

This study suggests that APC collagen peptides may accelerate hair growth and promote overall hair health by enhancing cellular proliferation and activating specific signaling pathways in human and mouse models.

This study hypothesizes that the curling of hair may result from the contraction of the Arrector Pili Muscle, contributing to the diverse types of curly hair.

This study hypothesizes that curly hair is shaped by the contraction of the Arrector Pili Muscle within the follicle, potentially modifiable through muscle-relaxing treatments, but further research is needed to confirm this mechanism.

This study found that in female patients with telogen effluvium, club hair in the isthmus region was longer than in those with alopecia areata, offering insights into hair morphology differences.

This study suggests that D-panthenol may promote hair growth by enhancing cell viability, suppressing apoptosis markers, and elongating the anagen phase in human hair follicle cells.

This review discusses the impact of various external factors like cosmetics, traction, and radiation on hair health and color, but reports no new findings.

This study found that hair follicle stem cells in mice have an unexpected ability to adaptively determine their differentiation pathways, maintaining tissue architecture despite external stimuli.

This study found that external application of DGD activates the Wnt/β-catenin signaling pathway, promoting hair follicle anagen phase entry, and is a more effective and safer treatment for androgenetic alopecia in mice compared to oral administration.

The study found that over-expressing ornithine decarboxylase in the outer root sheath of the hair follicle in mice increases UVB-induced tumor growth and invasive squamous cell carcinoma compared to inter-follicular epidermal keratinocytes.

This study observed that hepatocyte-like cells in canine circumanal glands are distinct entities that develop from hair follicle sheaths and later appear within sebaceous glands, without forming typical exocrine ducts.

This review summarizes current knowledge on tight junctions in mammalian skin and their role in drug delivery and interaction with other barrier components, but reports no new experimental results.

This review discusses the hair follicle cycle's complex regulation and highlights the potential for targeting catagen control in future therapies without presenting new experimental data.

This narrative review discusses the structure and functions of the skin, focusing on its barrier role, self-repair, thermoregulation, and immune functions, and reports no new experimental results.

This study found that cultured dental papilla cells from various mammals can induce hair follicle regeneration and influence tissue formation, with outcomes dependent on donor age, tooth type, and host environment.
