This study investigated the hair of German shepherd dogs, revealing variations in color, shape, and band patterns across different body regions, while all hair types shared similar anatomical structures such as continuous, vacuolated medullas and cuticular scales with smooth or rippled margins.

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.

Pili annulati is caused by a protein metabolism disorder affecting hair structure.

Human hair's structure makes it tough and resistant to breaking.

The connective tissue around hair follicles changes structure throughout the hair cycle.

This article explores the structure of mammal body hair and the challenges in explaining its evolutionary origins, reporting no new empirical findings.

This narrative review highlights the distinct needs of pediatric hair care, emphasizing gentler formulations due to differences in children's hair physiology, structure, and barrier function, and calls for targeted regulations and research due to limited safety evidence.

This article describes the development and growth stages of hair follicles during intrauterine life and subsequent growth phases on the scalp but reports no new clinical results.

This study suggests that the structure and function of the inner root sheath in mammalian hair may have evolved from simpler forms seen in monotremes, aiding in hair exit without damaging the epidermis.

This study found that the structure and mineral content of dromedary camel hair, specifically the medulla patterns, medulla index, and elemental composition, change with age, revealing differences among camels aged 1 year, 3-5 years, and 8-10 years.

This review discusses how dermoscopy enhances diagnostic accuracy in hair and scalp disorders, particularly distinguishing between conditions such as cicatricial and non-scarring alopecia, and offers insights into its practical uses in hair transplantation; it reports no new clinical results.

This study investigated the hair structure of wild pigs in the Balıkesir region using stereomicroscopy and scanning electron microscopy, finding distinct bifurcation patterns, but concluded that pig bristles used in brushes likely wouldn't retain these features, complicating species identification.

This study developed a model using homogenization-based framework to quantify solvent and solute flow across Janus membranes, aiming to better understand interface phenomena like osmosis and phoresis by examining micro- and macro-scale behaviors.

This review discusses the effects of vacuum massage on skin structures and concludes that there is insufficient evidence for its efficacy in treating burn scars, suggesting more research is needed on its potential benefits and mechanisms.

Hair can't be as strong as Rapunzel's because it's impractical to scale up due to defects.

This case report describes the unexpected hair repigmentation surrounding a scalp tumor in a 74-year-old man, suggesting a potential link between the carcinoma and changes in hair pigmentation.

This study shows that multiphoton microscopy can non-invasively distinguish scarring from non-scarring alopecia by identifying specific morphological features in hair follicle structures.

This study introduced a simple and reliable in vitro assay capable of large-scale simultaneous screening of hair growth-promoting compounds using a 3D co-culture system of human dermal papilla and outer root sheath cells.

This study observed that in chicken skin, large-scale differences in gene expression between feathered and scaly skin are controlled by enhancer-driven uniform expression, while small-scale differences within individual feathers are associated with chromatin looping.

This study found that an enzymatic digestion method for isolating hair follicle stem cells from scalp specimens yielded 5.3 times more epithelial cells than explant cultures, while supporting comparable cell functionality, offering a promising technique for tissue engineering and regenerative medicine.

In this study, Raman micro-spectroscopy did not support the hypothesis of structural changes in hair follicles due to miniaturization in women with androgenetic alopecia.

In this article, the authors describe how drug repurposing, supported by large-scale data and artificial intelligence, can make drug discovery more cost-effective and expedient compared to traditional methods, despite certain regulatory challenges.

This review highlights the need for standardized reporting on fucoidan extract properties to better understand the relationships between chemical structures and bioactivities, and to improve the quality and utility of fucoidan-related data.

In this study, lipid metabolism was found to be reduced in scalp tissues of patients with androgenetic alopecia, and lipid supplementation enhanced hair growth-related gene expression in human dermal papilla cells, suggesting a potential role for lipids in promoting hair growth through HIF-1 signaling.

This case report describes a 22-year-old woman with a nevoid plaque termed localized follicular hamartoma, characterized by skin-colored papules and specific cellular and structural features.

This study proposed and tested an Ensemble Pre-Learned Deep Learning and Optimized Long Short-Term Memory (EPL-OLSTM) model for classifying Alopecia Areata, achieving a 93.1% accuracy in differentiating healthy from varying severity levels of AA scalp hair using specific datasets.

This study isolated and characterized several chemical compounds from the leaves and flowers of Hibiscus rosa-sinensis, using spectral data and chemical reactions for structure elucidation.

This research developed a pig graph pangenome assembly of 27 genomes, revealing the importance of structural variations in adaptation and breed-specific traits, with BTF3 identified as a key gene influencing intramuscular fat and meat quality.

This study observed that the mechanical connection between hair follicles and connective tissue in human fetal scalp skin is weaker than in the corresponding skin components, reflecting dynamic processes in hair growth.

In this study, researchers observed that loose anagen hair syndrome is an autosomal dominant disorder characterized by abnormal hair follicle structure and premature keratinization, possibly due to signaling and desmosomal component disturbances.
