This study found that in naturally curved human scalp hairs, distinct arrangements of cell types on either side of the hair fiber contribute to its curvature.

This review discusses the genetic and biological factors influencing hair curliness, revealing strong links to specific protein variations, and reports no new clinical results.

This review highlights advancements in 3D bioprinting for skin tissue engineering, focusing on exosome-loaded bioinks that show potential for enhancing skin regeneration and repair.

A missing mK6irs1 gene causes hair loss in mice.

This study explored the complex developmental processes of human hair, emphasizing the intricate interactions required for hair follicle morphogenesis and its implications for drug incorporation and concentration interpretation, particularly in early childhood.

This review examined the role of the ion channel TRPV3 in warmth sensation and skin physiology, discussing controversies around its direct contribution to temperature perception, its involvement in skin health, and its potential as a therapeutic target for skin diseases.

This study developed a 3D bioprinted skin model to mimic pemphigus vulgaris, providing a tool to study disease mechanisms and test targeted therapies by reproducing the architecture and pathogenic disruptions of native skin.

In this in silico study, researchers analyzed nonsynonymous SNPs in the LIPH gene linked to hypotrichosis and identified three potentially harmful variants (W108R, C246S, and H248N) out of 215 total, using sequence- and architecture-based bioinformatics techniques to differentiate between harmful and benign SNPs.

In this study, forced expression of the transcription factor cDermo-1 in chicken dermis led to the formation of ectopic feather buds and enhanced feather growth, demonstrating its role in initiating skin appendage development.

This review discusses the role of microglia in mediating prenatal androgen effects on the female brain, potentially contributing to PCOS development and neuroendocrine dysfunctions, but reports no new results.

This study observed that repeated low-depth microneedling in patients with androgenetic alopecia led to initial hair improvement but subsequently caused hair-shaft fragility and breakage, suggesting iatrogenic damage.

This chapter reviews surface plasmon resonance (SPR) methodology and its applications in basic science and human disease without reporting new clinical results.

This study suggests that the mechanical robustness of hair may be enhanced by the binding interactions of keratin-associated proteins, particularly KAP8.1, with intermediate filament proteins.

Androgens like testosterone affect skin health and can lead to conditions such as acne and hair loss, with various treatments available.

This study identified 77 genes with significant expression changes in expanded human skin, suggesting possible mechanisms for skin regeneration during tissue expansion, including previously unreported genes like HOXA5, HOXB2, and AP1.

This study found that the Epilight multiple wavelength pulsed-intense light source was effective for long-lasting hair removal, particularly in individuals with dark hair and light skin.

This study reported that the new near-infrared LED device showed significant improvements in skin rejuvenation and a slight increase in hair growth, with further research recommended for broader validation.

This study investigated the penetration of a low-molecular-weight cationic conditioning compound into the hair cortex and suggests it may improve hair's fatigue resistance.

This review explores the biology of wool follicles and suggests their potential use as research models in modern biology, but it reports no new findings.

This study presents guidelines for designing female hairlines, noting that most women in the sample had a widow's peak and specific average measurements for hairline features.

In this study, the bending stiffness of human hair was linked to the varying proportions of para-like versus ortho-like cortical cells within the hair fiber.

Using cheek skin and cartilage grafts for nose reconstruction after skin cancer surgery can maintain shape and function but may require multiple surgeries and hair removal in men.
