In this study, significant changes in hair fiber dimensions were observed between pre- and post-operative states in males undergoing abdominal surgery, with values normalizing by the fourth post-operative week.

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.

In this study, optical coherence tomography was used to produce 3D images of human hair, revealing that after chemical treatment with ammonium thioglycolate, the main hair structures were not identifiable due to damage.

This study found that the cuticle layer of hair contributes approximately 60% to bending stress, highlighting its significant role in the mechanical properties of hair stiffness.

This study found that torsional measurements can effectively distinguish the effects of hair care products on the cuticle versus the cortex of hair fibers, unlike tensile measurements.

Hair increases in size when it absorbs water, and treatments like bleaching affect how much water it can take in.

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 investigated the effects of ammonium thioglycolate and amino methylpropanol hair straightening followed by permanent coloring, finding significant physical and chemical changes to both the cuticle and cortex of hair fibers.

This anatomical study on Eclipta alba concluded that unique secretory structures in stems and leaves may serve as identifying features of the plant and the Asteraceae family.

In this study, liposome-encapsulated thioglycolic acid improved hair perming by enhancing the penetration of perm solutions, resulting in a stronger S-shaped wave and higher cysteine content compared to the control.

This study reports that different animal species exhibit distinct hair scale patterns and elemental compositions, which can aid forensic investigations in identifying animal hair.

In this study, researchers found that the morphology, composition, and elemental enrichment of domestic cat hairs vary significantly along their length, contributing to a functional gradient that affects mechanical properties and challenging assumptions of uniformity in hair structure.

This study found that in the Thai population, hair density varies by scalp location and decreases with age, and that Asians generally have lower hair density compared to Caucasian and African populations.

In this study, Arab hair was found to have a higher thickness and lower density compared to other ethnicities, suggesting these factors should be considered in diagnosing and treating hair issues in Arabs.

This article provides an overview of hair density, hair diameter, and the prevalence of female pattern hair loss but reports no new clinical findings.

This brief article is a response from the authors about hair density, hair diameter, and female pattern hair loss, and it reports no new clinical findings.

In this study, researchers identified three molecules in hair that varied with age, suggesting potential markers for aging and targets for cosmetic products.

This article reviews the types and characteristics of adrenal cortex tumors, including their hormone secretion and detection as incidental findings, but presents no new research results.

This study reports that scalp biopsies in white adults usually have 16.5 hair follicles, primarily in the anagen phase, with male samples showing fewer follicular units but more fibrous tracts in certain areas.

A score of 6 or less is recommended to diagnose hirsutism in Colombian women.

This abstract describes monilethrix, an autosomal dominant genodermatosis with symptoms like hair fragility and keratosis pilaris, and does not report new experimental results.

This article reviews the historical development of understanding the hair growth cycle, particularly anagen, catagen, and telogen phases, and reports no new clinical findings.

This study discovered a new region in the hair cortex where intermediate filaments are both aligned with the hair's axis and orientationally ordered, influenced by the cuticle boundary.

This study found that bleached hair showed optimal protein structural integrity and tensile strength at pH 5, with significant changes in cross-linking, water content, and diameter at more alkaline or acidic levels.

This study found that coconut oil impedes hair hydration more effectively than soybean oil by penetrating deeper, and suggested a new model for intermediate filament assembly in hair.

This study found that African and Caucasian hair contain the most lipids, and depletion of these lipids leads to less water retention and increased water desorption, with Caucasian hair showing improved breaking tenacity after lipid extraction.

The book discussed in this abstract is a comprehensive guide to hair analysis, detailing the latest methods and applications across various fields such as toxicology and drug monitoring, designed for both newcomers and experts in the field.

The document explains how hair is studied in forensics to identify its source and its role in criminal investigations.

Atomic Force Microscopy is a more accurate way to assess hair damage and the effect of cosmetic treatments.
