This study found that hair curvature in merino wool is influenced by differences in cell type length rather than the proportions of orthocortical and paracortical cells.

This article reports electron microscope studies on the structure of hair and wool, but it does not present new clinical findings.

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 study suggests that varying intersheet interactions may explain the differences between the two polymorphic forms of macrofibril assembly in Merino wool and hair.

Merino wool fibers change shape with moisture, while human hair shape stays the same.

This study observed that the molecular structure of keratins in hair fibres' discrete transition zone differs in breast cancer patients, with altered lipid ester absorption bands reverting post-cancer removal.

This study found that the curl in hair is due to the arrangement of different cell types, with shorter paracortical cells inside the curve and longer orthocortical cells outside.

This study found that straight crimp mutant wool differs from crimpy wool in the layout of cortical cells and the relative proportions of keratin and keratin-associated proteins.

This research explores the use of serial block-face scanning electron microscopy to model the complex architecture of sheep wool fibres, focusing on the role and distribution of para- and ortho-cortical cells in determining wool curliness, though the mechanism remains unclear.

This paper reviews the complex anatomy and development of human hair and emphasizes the need to understand these processes for interpreting drug incorporation into hair, with no new clinical results reported.

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.

This study introduces a modular fiber model to investigate how changes in microstructural properties of wool affect its critical buckling load, highlighting potential uses and areas needing further research in wool fiber biophysics.

This article reviews the genetic and protein interactions involved in hair growth, highlighting regulatory sequences, expression patterns, and potential genetic modifications, but presents no new experimental findings.

This article discusses themes in the molecular structure of hair and reports no new research findings.

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 chapter reviews the complexity of hair and wool follicle formation, emphasizing the importance of cytological studies to understand the relationship between cellular components.

This study observed that genetic variation in the ovine KRTAP22-1 gene is linked to increased wool yield and decreased fiber curvature in sheep, indicating its potential use in breeding programs.

This paper reviews hair structure and damage from grooming and cosmetic exposure but reports no new clinical findings; it suggests collaboration between dermatologists and cosmetic chemists to improve hair care products.

In this study, experimentally induced weight loss in merino sheep led to a decrease in wool fiber diameter and increased expression of certain high sulfur and glycine-tyrosine proteins, potentially impacting wool quality and industry preferences.

This review proposes a new approach for categorizing and diagnosing unruly hair forms, building on previous literature and clinical experience, without presenting new clinical results.

This research examined the ultrastructure of deer hair fibers and found significant variations in diameter, cuticle thickness, and intermediate filament arrangements among different fiber types.

This study found that crossbred lambs fed liquid diets with reconstituted cow's milk initially grew wool without crimp, with crimp resuming two weeks post-weaning.

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.

The researchers reported that keratin 33A is a structural protein specific to goat cashmere hair, with increased winter expression in high-cashmere-producing breeds.

In this study, the expression of certain hair follicle-related genes differed between growth phases in Angora goats, with HOXC13 showing overexpression during the anagen phase, potentially influencing the mohair's shine and texture.

This review highlights how forensic drug analysis in hair using modern instrumental techniques offers advantages such as easy sample collection and chronological tracking of drug use, emphasizing its value for law enforcement and other applications.

This chapter reviews techniques for treating pseudofolliculitis barbae and suggests that combining daily shaving with topical treatments like glycolic acid may effectively manage this condition without new clinical results reported.

This study aims to develop and evaluate herbal shampoo powder made from natural ingredients, focusing on its efficacy in removing debris and dandruff, enhancing hair development and shine, and strengthening and darkening hair. Results are not reported.

In this study of Angora goats, researchers found that HOXC13 and other genes were overexpressed during the active hair growth phase, suggesting a role in mohair structure.

This study found that HOXC13 gene expression was significantly higher during the anagen phase in Angora goats, potentially contributing to the mohair's shiny and silky nature.
