This review examines regenerative hair waves and complex hair cycle domains in transgenic mice, highlighting how these dynamic processes contribute to skin regeneration and the physiological regulation of organs, but reports no new experimental results.

This study concluded that epidermal growth factor may induce a 'catagen-like' phase in human hair follicles by disrupting normal cellular proliferation and migration patterns.

In this study, researchers found that disrupting the PRL gene in mice led to earlier hair molting, especially in females, suggesting that PRL inhibits murine hair cycle events.

This study found that the mechanical stiffening of the human hair follicle along the first millimeter is linked to changes in the keratin network architecture and composition during keratinization.

This study concluded that bleach treatment partly transforms the hydrophobic top layer of human hair cuticles into a hydrophilic surface with clustered cysteic acid, visualized at the nano-scale using dynamic Chemical Force Microscopy.

This article reviews the role of polyamines in hair follicle growth and discusses potential therapeutic applications but provides no new clinical results.

This study reports that milk goats exhibit significantly more differentially expressed genes related to hair follicle cycling across different months compared to cashmere goats, especially in December.

This study identified a novel gene, hacl-1, that is specifically expressed in the hair follicles of ICR mouse skin and is associated with their active state.

This study found that colchicine treatment significantly reduced hair fiber elongation in cultured hair follicles and altered protein expression and activity in dermal papilla cells, suggesting a role for the ubiquitin-proteasome system in its effects.

This study found that disrupting the PRL gene in mice alters the timing of hair cycling events, causing earlier molts and changes in hair characteristics, particularly affecting female mice more significantly.

This review outlines the development and functional requirements of modern wound dressing materials and describes preparation methods and product performance, but reports no new clinical findings.

This review discusses the limitations of current hair classification systems and highlights the need for standardized reporting of key hair characteristics to improve study comparisons; it reports no new results.

In this study, researchers found that UV radiation causes hydroxy radicals to form cuticle holes specifically between the cuticle layers in wet hair, unlike random holes caused by Fenton's reaction.

This study found that the uptake of molecules by hair is influenced by both hydrophobic and ionic charge interactions, with binding affinity decreasing as pH approaches the solute's dissociation constant.

In this study, researchers demonstrated that human hair keratins can self-assemble into stable nanofibrous networks in vitro, which are compatible with human skin cells and useful for regenerative applications.

This study found that the medulla of Japanese hair contains unsaturated lipids such as squalene and oleic acid, which may contribute to hair glossiness.

In this study, UVB exposure was found to alter certain chemical properties of the hair shaft, such as keratin components and water content, without significantly affecting its physical morphology.

This review discusses hair straightening techniques, products, and safety risks, providing guidance for dermatologists to advise patients effectively; it reports no new clinical results.

This study used rapid-freezing immunocytochemistry to successfully map the ultrastructural localization of hair keratins in human scalp hair, primarily finding them in macrofibrils in the cortex and endocuticle.

This review discusses various forensic applications of hair analysis, such as species identification and drug addiction testing, and reports no new study results.

In this study, researchers explored hair follicle development in Qianhua Mutton Merino sheep, identifying key genes like KRT27 and IGF-2 that impact this process, with findings suggesting significant molecular changes as sheep mature from newborn to one year old.

This study found that down and guard hairs of Inner Mongolia Cashmere Goats have distinct protein compositions and physical properties, with keratin-related proteins potentially influencing these differences.

This study demonstrated that cryogelation of human hair keratin allows the development of 3D scaffolds with tunable properties, supporting cell adhesion and proliferation for potential biomedical applications.

This case report describes a new family with autosomal recessive hypotrichosis simplex with woolly hair, suggesting the disorder may be underreported due to misdiagnosis.

This study identified two single-nucleotide polymorphisms and three haplotypes in the KRTAP7-1 gene across yak, taurine, and zebu cattle, with the BOVIN-KRTAP7-1*A haplotype most prevalent.

Keratin fibers in hair twist left-handed.

Keratin-based hydrogels from human hair improve wound healing effectively.

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 study identified the expression sites of five KAP5 genes on human chromosome 11q13.5 in scalp skin sections but did not explore their detailed distribution within hair follicles.

Hair follicles have unique proteins that vary by species and are influenced by nutrition.
