This article discusses the diagnostic challenges between certain neonatal scalp conditions and highlights the potential of line-field confocal optical coherence tomography to provide detailed, non-invasive skin examination, without presenting new clinical findings.

In this study, researchers used atomic force microscopy to capture and analyze morphological changes in the surface of healthy hair, identifying features such as pitting and rod-shaped macro-fibrillar elements, which could inform future research on hair conditions and care.

This study introduces a new method to isolate stem cells from the hair follicle outer root sheath of equine skin, demonstrating that these cells, named eMSCORS, proliferate efficiently and can differentiate similarly to adipose tissue-derived MSCs, offering a promising alternative for equine veterinary applications.

This study identified new geometric and mechanical parameters for curly and kinky/coily hair, which may inform more effective personal care products tailored to these hair types.

This study suggests that IL-33 promotes hair follicle changes and T cell infiltration in psoriatic mice and humans, contributing to psoriatic alopecia.

This study observed that in Assam Hill Goats, the primary hair follicles had larger diameters and more structural associations compared to secondary follicles, especially in ruminant-age groups.

In this study, low-dose 453 nm blue light appeared to enhance hair growth by interacting with specific photoreceptors in the outer root sheath cells.

In this study, the reconstructed skin epidermal model derived from hair follicles showed gene expression and enzyme functionality consistent with native human skin, suggesting its viability for studying skin metabolism and potential toxicity of dermo-cosmetic ingredients.

This study found that hair follicle matrix progenitors differentiate into various layers asynchronously, with early progenitors forming the companion layer and later progenitors generating the inner root sheath and hair shaft.

This study identified that in mice, sweat gland development is directed by mesenchymal signals that suppress SHH-production, while in humans, this occurs through a BMP spike in embryonic development.

Activating the Eda/Edar pathway improves wound healing by enhancing hair follicle growth.

This study employed a laser-based method to analyze how light reflection patterns vary on human hair fibers, revealing changes related to hair color and the tilt of the cuticle cells.

This study observed that PAD type III and trichohyalin are expressed earlier than their deiminated form during the first and second hair cycles in rat hair follicles, indicating a potential additional factor is involved in triggering deimination.

This study reported that platelet-rich plasma therapy significantly increased hair density and diameter in men with androgenetic alopecia by inducing morphological changes in hair follicles.

This study found that Cutl1 mutant mice experienced retarded lung differentiation and abnormal hair follicle morphogenesis, indicating the vital role of CDP in lung development and hair follicle cell-lineage specification.

In this study of patients with Androgenic Alopecia, micro-grafts containing HD-AFSCs resulted in significantly improved hair density and follicle count over 11 months compared to a saline solution, suggesting a potential alternative therapy for hair regrowth.

This study presents a novel in vitro assay using human folliculoid microspheres to research hair growth, which may facilitate preclinical testing of hair growth-modulatory agents.

This study found that the transcription factors Msx2 and Foxn1 are crucial for maintaining Notch1 expression in the hair follicle matrix, which is necessary for proper hair differentiation.

This study found that Notch-related genes, including Notch1 and Notch2, and their ligands and regulators, have distinct patterns of expression during mouse hair vibrissa follicle development and the adult hair cycle.

This study found that permanent alopecia can occur after certain chemotherapy treatments and presents as nonscarring hair loss similar to androgenetic alopecia, with specific histological features that could be misdiagnosed without proper clinicopathological correlation.

Fibronectin and other basement membrane components increase during hair growth and decrease during rest.

This study visualized mitochondrial metabolism in cultured bovine hair follicles and plucked human hairs, finding that ROS and mitochondrial polarization correlate in specific hair follicle regions, particularly near keratin deposition sites.

This study found that the S100A3 gene is exclusively expressed in hair follicle cells differentiating into hair shaft components in mice, suggesting its important role in hair formation.

This article examines the role and composition of integral hair lipids in forming a protective barrier similar to the skin's epidermal lipid layer and reports no new findings about their effects.

Testosterone was found to inhibit hair follicle epithelial cell proliferation in adult stumptailed macaques only when dermal papilla cells from bald scalps were present, and this effect was reversed by the antiandrogen RU 58841.

This study observed dynamic changes in CD10 and CD34 expression in fetal and adult human hair follicles during embryogenesis and hair cycling.

In this study, high concentrations of dihydrotestosterone and testosterone reduced the growth of human hair follicle cells in vitro, while high estradiol levels increased their growth.

This article reviews the role of adult stem cells in tissue homeostasis and wound repair, focusing on their regulation within the murine hair follicle's specialized niche, but it presents no new findings.

This study reported that Panax ginseng extract significantly inhibited DKK-1-induced catagen-like changes in human hair follicles by promoting cell proliferation and reducing apoptosis, suggesting it may help mitigate hair loss associated with DKK-1.

In this study, researchers used a rodent model to uncover key changes in how hair fibers detach, suggesting that the exogen phase should be subdivided based on club fiber status.
