In this study, the researchers found that transplanted hair follicles undergo significant morphological changes, including a thickened dermal sheath and increased hair shaft diameter, which are associated with altered follicular vascularization.

The document concludes that hair analysis is not good for assessing nutrition but can detect long-term heavy metal exposure.

This review highlights that Tremella fuciformis polysaccharide exhibits various bioactivities, such as antioxidant and immune-modulating effects, and explores its potential applications in food, pharmaceutical, and cosmetic industries.

This study reported that knocking out the HR gene in pigs using CRISPR/Cas9 led to hairless eyelids and abnormalities in the thymus and peripheral blood, suggesting pigs as a model for human HR-related hair disorders.

KAP8.1 protein is crucial for hair structure and interacts with keratin 85.

This study found that age-related hair thinning in Caucasian women over 50 involves significant structural changes within the hair follicle, suggesting an "aged hair program" rather than just producing thinner hairs.

This study identified key genes linked to immune cells and potential therapeutic compounds for alopecia areata by evaluating upregulated genes from patient datasets, highlighting T and NK cell involvement in hair follicle attack and suggesting drug candidates through molecular docking and dynamics simulations.

This review explores how hair dyes and perms can damage hair structure and notes that while some adverse outcomes like skin irritation and allergic reactions have been reported, evidence from human studies remains inconsistent regarding potential risks, including cancer.

This proof-of-concept study reported that a new, ultra-fast, one-step immunohistochemistry method improved the interpretation of Mohs surgery slides, particularly for poorly differentiated tumors.

This research reports that the polyG fragment within the Hoxc13 protein alters its gene regulatory functions, which could have influenced mammalian hair evolution by affecting pathways related to hair follicle development.

This study analyzed changes in the microbiota during antler velvet regeneration in sika deer and found significant differences in microbial community composition between 15 and 30 days post-pedicle casting, highlighting the potential roles of specific bacteria in wound healing and tissue regeneration.

In this study, researchers identified three novel genetic loci associated with androgenetic alopecia, including one with significant association in females only, which may indicate a role for sex-specific genetic factors in patterned hair loss.

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 review discusses various pediatric hair loss conditions and treatments, highlighting the importance of a holistic approach and noting that no single treatment is universally effective.

This review discusses the role of hair microscopy in diagnosing alopecia, stating that while it excludes diagnoses related to hair breakage, it only confirms nonspecific short anagen in alopecia cases.

This review explores the complex interrelationships among different properties of natural hair fibers and underscores the need for a holistic taxonomy to improve data interpretation across disciplines, but it reports no new experimental results.

This study found that moisture sorption properties of wool and hair fibers from various animals were similar, despite different structural features, with sorbed water being more ordered than liquid water.

This study found that pelage abnormalities in Harlequin mutant mice are linked to severe AIF deficiency and associated with altered expression of genes related to hair structure.

Improving knowledge and practices in animal fibre production is crucial to meet market demands and potentially revive natural fibres.

This study identified two distinct fibroblast subsets in mouse skin, revealing that adult skin scarring occurs due to the repair process utilizing only one, lineage-restricted fibroblast type instead of coordinated diverse populations.

This study compared the effects of three compounds on structural and sensory benefits for bleached hair when applied with or after bleaching, observing that their application may mitigate bleaching-induced damage.

This review discusses the expanding understanding of TRPV3's role in pain and skin pathology, while highlighting the need for further pharmacological research to fully resolve its functions.

This study found that the volume of a hair follicle's dermal papilla is strongly correlated with its size, primarily due to the number of cells it contains and the volume of extracellular matrix.

This article reviews common hair growth abnormalities in children, emphasizing the importance of distinguishing normal development from potential signs of metabolic disorders and indicates no new clinical results.

This study found that human hair follicle stem cells formed more colonies and adhered more rapidly, while transit-amplifying cells showed significantly greater mobility.

In this study, mutations in the CDH3 gene were identified as the cause of hypotrichosis with juvenile macular dystrophy, and the researchers observed substantial phenotypic variability among affected individuals.

This study found that the yellow dot pattern observed in dermoscopy of alopecia areata corresponds to inefficient follicular structures containing hair remnants, as corroborated by reflectance confocal microscopy and pathological findings.

This review discusses the sex differences in neuroactive steroid synthesis and their implications for nervous system functions and potential therapeutic approaches, but it provides no new experimental results.

This review presents an objective analysis of female androgenetic alopecia, discussing clinical and dermoscopic examination approaches but reports no new clinical findings.
