In this study, researchers found that the curliness of human hair is associated with an asymmetric structure at the cellular level, particularly in the differentiation of the precortex.

This study reports pseudopili annulati in a dark-haired Chinese girl, identifying the unique appearance and structural characteristics of her hair without finding abnormalities in the cuticle and cortex.

In this study, a new shading model for hair was developed that better matches real-life light scattering, thanks to detailed new measurements of hair fiber scattering not predicted by existing models.

This study introduced a new hair shading model that more accurately simulates light scattering on hair fibers, capturing effects not predicted by previous models.

This study reviewed scalp biopsies from African-American patients, identifying distinct features and diagnostic clues for scarring alopecia types such as traction alopecia and central centrifugal cicatricial alopecia.

This study found that androgenic alopecia is present in 22% of women with polycystic ovary syndrome and is associated with other clinical signs of hyperandrogenism, but not with increased biochemical hyperandrogenemia or metabolic dysfunction.

This study examined developing hair cortex with electron microscopy and found that keratin fibrils form between specific regions in hair follicles and aggregate into twisted cables.

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.

Human hair's ability to get wet is complex and can change with treatments, damage, and environment.

This study found that thermal hair-straightening devices significantly damaged the cuticle and cortex of virgin Asian and Caucasian hair, with Asian hair experiencing more protein loss than Caucasian hair.

This review highlights the lack of research on Afro-textured hair, emphasizing the need for better understanding of its genetic traits and molecular structure to develop more effective hair care solutions.

This study investigated the effects of wool-derived hydrolysed keratin peptides on relaxed textured hair and found that mid- and high-molecular weight peptides improved mechanical strength and reduced breakage in different humidity conditions.

This case study describes a 4-year-old boy whose neck tumor was initially misdiagnosed as scrofuloderma before being correctly identified as a pilomatricoma, underscoring the need to include pilomatricoma in differential diagnoses for persistent skin lesions.

This study observed that lipids in human hair accumulate in specific areas and do not significantly impact water permeability, highlighting the utility of AFMIR for studying complex biomaterials.

This study identified a unique concentric double-layered structure in both Japanese and Caucasian SHINAYAKA hair, associated with improved flexibility and elasticity, and developed a succinic acid treatment to enhance these properties.

Monilethrix involves multiple genes affecting hair structure, including DSG4 mutations.

This case report describes a 14-year-old female patient with monilethrix who developed female androgenetic alopecia at age 23, and found that oral minoxidil treatment improved her androgenetic alopecia while leaving the underlying structural hair anomalies of monilethrix unchanged.

This study found that postmortem root banding in hair is likely due to the degradation of the intermacrofibrillar matrix in the cortex, with no damage to the cuticle observed.

This study of African-American women found that those perceiving greater hair breakage showed lower break stress and higher premature failure rates, linked to grooming practices and hair curvature.

In this study, the researchers found that a manual micrometer caliper is a reliable tool for planning hair transplant surgery and accurately measures the short axis of the hair shaft.

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.

This review discusses the genetic disorder, monilethrix, characterized by fragile, brittle hair and its inheritance patterns, and reports no new clinical results.

This chapter reviews hair anatomy, hair shaft structure, and various cosmetic treatments that can alter or damage hair, but it presents no new research findings.

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 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 chapter reviews the anatomy and structure of hair, discusses hair damage and analyses, and explores methods for processing hair changes, but presents no new research findings.

Hair care products are important for appearance and self-esteem, and choosing the right ones can help maintain healthy hair.

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

This paper reviews different types of hair shaft dysplasias and does not report any new clinical findings.

This study found statistically significant patterns in hair morphology and ultrastructure linked to biogeographic ancestry among European, African, and East Asian populations.
