This study employed a laser-based method to analyze how light reflection patterns vary on human hair fibers, revealing changes related to hair color and the tilt of the cuticle cells.

This study found that laser-based goniophotometry can effectively monitor changes in hair surface reflection related to color and cuticle cell tilt across different ethnic origins.

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 identified two evolutionarily conserved ultra-high-sulfur keratin proteins in human and sheep hair follicles, which are specifically expressed in the hair cuticle during the late stages of fiber development.

This study identified the expression sites of five KAP5 genes on human chromosome 11q13.5 in scalp skin sections but did not explore their detailed distribution within hair follicles.

This article describes the structure and components of hair cuticle cells and their intercellular junctions but reports no new clinical results.

This study found that keratin-associated proteins form part of the developing exocuticle and a-layer in hair fiber cuticle cells, while cornified envelope proteins were absent.

In this study, researchers found that UV radiation causes hydroxy radicals to form cuticle holes specifically between the cuticle layers in wet hair, unlike random holes caused by Fenton's reaction.

This review explores the structure and development of the hair cuticle, highlighting difficulties in studying some aspects and proposing new experimental approaches, but reports no new clinical results.

This study reports that activating Notch signaling in the hair follicle cortex of transgenic mice caused abnormal differentiation of the medulla and cuticle, highlighting potential cell-cell interactions.

This study found that mu-crystallin gene expression in mouse skin is highest during the anagen phase of hair development, suggesting its possible role in hair follicle growth.

This study found that keratin derivatives with functionalized thiol groups improved binding to both natural and bleached hair fibers, suggesting a promising strategy for enhancing keratin's durability in hair repair.

This study found that both everyday physical and environmental stresses, as well as chemical treatments, contributed to hair damage, with cuticle layers being more noticeably affected.

This study suggests that corkscrew hairs in tinea capitis result from internal hair damage by Trichophyton violaceum and external resistance from scalp scales.

This study found that water hardness metals like calcium and magnesium can stiffen hair fibers, reduce combing forces, and affect style retention, with varied effects on virgin and bleached hair.

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 reports a good correlation between the curvature of human eyelashes and the displacement of the neutral axis, influenced by the non-uniform thickness of the outer cuticle layer.

This study found that CMAD wool keratin may protect human hair from damage during repeated bleaching and permanent waving treatments.

This study provides conclusive evidence of exogenous calcium fatty acid deposits forming between the cuticle layers in hair, affecting its optical and mechanical properties.

This study found that stepwise thermal treatment of human hair waste at temperatures from 200 to 450 °C produced hollow microtubes, with structure changes influenced by temperature, core degradation, and cortex melting.

This study found that peptidylarginine deiminase type III and trichohyalin are coincidentally expressed in the infant rat hair follicle, but trichohyalin deimination occurs after their expression during development.

This study found that age-related hair thinning in Caucasian women over 50 involves significant structural changes within the hair follicle, suggesting an "aged hair program" rather than just producing thinner hairs.

This study found that pubic hair from Korean males has a thicker cuticle layer with more scales compared to scalp hair, offering better protection against chemical damage, and hypothesizes this evolved as a defense mechanism against exposure to urine and ammonia.

This study found that ceramide-based essence cream, particularly those with stearyl and stearyl-cholesterol, improved the ultrastructure of damaged hair cuticles.

This study observed that hair follicle cuticular cells undergoing keratinization were significantly thicker than those in a normal hair shaft, due to incomplete loss of cytosol.

This study observed that long-term UV-A exposure and semi-permanent dye treatment can cause significant structural damage to human hair, particularly affecting the cuticle and cortex layers.

This study found that treatments like abrasion, bleaching, and CETAB application affect hair fiber shear modulus differently, with moisture levels notably impacting bleached fibers more than untreated ones.

In this study, researchers found that neonate hairs have a distinct microstructure with no medulla and smaller hair follicles compared to adult hairs.

This study used ultrahigh-resolution optical coherence tomography to observe hair shaft structures, finding melanin granules absent only in white hair, which may explain color differences between black and white hair.

This study demonstrates that confocal laser scanning microscopy can effectively visualize the rapid diffusion and penetration pathway of a dye into the hair follicle in fresh human scalp skin.
