In this study, researchers used SEM/SDD-EDS to identify waterborne minerals like calcium and aluminum in the scalp hair cuticle of individuals using treated or untreated water for hair washing, finding that prior application of coconut oil or conditioners can prevent calcium uptake.

This study found that despite chemical differences, five different brands of reconstructive hair fibers all provided successful cosmetic results in disguising hair loss in patients.

In this study, researchers found that patients with Friedreich's ataxia exhibited more pronounced ultra-structural hair alterations compared to carriers, likely due to oxidative stress related to deficient frataxin expression.

This study presented a case of tinea capitis in a 4-year-old without typical symptoms and traced the infection to Microsporum canis carried by domestic cats, highlighting the need for accurate diagnosis and appropriate treatment, especially in households with pets.

This study observed distinct changes in the ultrastructure of Hexi cashmere goat hair follicles throughout the year, highlighting stages with specific cellular and structural characteristics.

This study observed that mink dermal collagen fibrils undergo structural changes during the hair cycle, with increased fiber thickness and bundle density as minks grow.

This microscopy study examined the non-keratinous regions of human hair fibers, revealing detailed morphology that could help understand how external influences affect hair structure.

This study investigated the effects of intensive hair dye use in mixed-breed dogs and found changes in the cuticle of the hair shaft and the epidermis using scanning electron microscopy.

This study found that scanning electron microscopy revealed significant hair shaft changes in women using straighteners, but not in those using hair dye, suggesting its utility in assessing chemical treatment effects on hair.

This study reports that trichocyte intermediate filaments from rat vibrissae and human hair follicles may contain a hollow region at their core, suggesting unique structural properties.

This study documents dominant transmission and complete penetrance of uncombable hair syndrome in a family, despite the father lacking visible abnormalities.

In this study, researchers observed that cosmetic peroxide bleaching causes oxidative damage and protein loss in human hair, not only affecting the cuticle but also deeper cortical structures, correlating with bleaching severity.

This study describes a modified reduction-osmication method for staining human scalp hair that improves reagent penetration and visualization of hair cortex features using transmission electron microscopy.

This article describes the structure of ovine interdigital sinuses using scanning electron microscopy, highlighting features such as dense secretory material, hair presence, and classical apocrine secretion characteristics.

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.

This study developed a quantitative measure for scoring hair surface damage from SEM images and found it accurately classified hair damage caused by explosive blasts, similar to an existing classification system.

This study assessed whether the elemental composition of human hair could serve as a marker for kidney stones, cholelithiasis, hypertension, and diabetes, but it reports only variations in element content along hair regions.

This study found that scanning electron microscopy with argon sputter etching visualizes hair lipids at the cell membrane complex as distinctive convex structures, shedding light on their role and localization in human hair.

Hair shaft changes may be linked to CCCA, but their role is unclear.

This study found that while hair washed with hard water had higher magnesium deposits, it did not show significant structural surface changes compared to hair washed with soft water.

In this study, a 3-year-old Japanese child with autosomal recessive woolly hair was found to have a distinctive irregular and rough cuticle on the hair shaft, along with a homozygous pathogenic LIPH variant, suggesting a critical role for genetic analysis in understanding rare hair conditions.

In this study, researchers examined juglone's potential as a restoring agent for hair keratin damaged by permanent or bleaching treatments, finding that juglone formed Michael adducts with cysteine residues, leading to a more regular hair surface as observed via IR spectroscopy and SEM analysis.

Hair shaft malformation contributes to Central Centrifugal Cicatricial Alopecia.

This study found that using ionic liquid for specimen preparation allowed for observation of dermal papilla cells and their cilia in near-living conditions, reducing damage typically caused by conventional preparation methods.

This study used novel methods to detect and map iodine concentrations in pig skin, finding iodine present in the coating, stratum corneum, and tissue around hair follicles.

Zinc deficiency causes early scalp hair damage that recovers slower than skin symptoms.

Hair fibers break by cuticle cell slipping, shape changing, cuticle fraying, and surface cracking when stretched under specific conditions.

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

This study observed that daily selenium sulfide shampoos successfully removed fungal spores hidden beneath the hair cuticle in patients infected with ectothrix Microsporum canis.
