This study found that human hair cuticle and cortex have different protein structures, with beta-sheet and disorder configurations in the cuticle and alpha-helical structures in the cortex.

This study found that permanent waving treatment partially disrupts the α-helical structure in human hair microfibrils, primarily during the initial reduction phase, rather than just affecting disulphide bonds.

This study detailed the structure and amino acid composition of sheep trichohyalin, noting its presence in various tissues and suggesting a possible functional role beyond structural support in hair follicles.

This study used proteomic techniques to analyze human hair proteins, revealing keratin heterogeneity and identifying posttranslational modifications, such as cysteine trioxidation and methylation.

This study found that alopecia areata patients with a CCHCR1 gene variant had higher recurrence rates and structural abnormalities in hair compared to those without the variant.

This study identified trichohyalin as an early differentiation marker in hair follicles, with potential structural roles related to alpha-helical formations, based on the partial characterization of its cDNA in sheep.

This study found that permanent wave treatment accelerates hair degradation after protease exposure, showing significant morphological differences compared to untreated hair and linked to damage from Alpha-helical region denaturation.

This study suggests that human trichohyalin may function as a flexible rod linking keratin intermediate filaments and as a scaffold protein in hair follicle and epidermis cell envelopes.

This study found that permanent waving treatment induces structural changes in the cortex proteins of white human hair, significantly reducing its tensile strength without altering the S-S band intensity.

This study presents computational modeling and experimental analysis of the HGT protein KAP8.1, identifying key structural features that may influence hair's response to environmental conditions.

This study found that the molecular structure of hair is more sensitive to synchrotron X-ray radiation than its supramolecular architecture, indicating potential concerns for biological analyses using such radiation.

This study found that using a microfiber towel to dry human hair better preserves hair keratin integrity and wear resistance compared to blow-drying or using a cotton towel, as indicated by stronger alpha-helix structure in FTIR analysis.

This review explains the mechanical composition and molecular interactions that determine hair's mechanical properties, without providing any new experimental findings.

This study observed that increasing the γ-kerateine content in meta-kerateine materials led to reduced elasticity, solidity, and hydrolytic stability, and decreased hepatocyte attachment support.

The study improved understanding of keratin fiber structure by showing consistent microfibril diameter but varying distances and electron density profiles.

This review summarizes the anatomical and physiological aspects of human hair and its clinical significance, but does not report new research findings.

In this study, UVB exposure was found to alter certain chemical properties of the hair shaft, such as keratin components and water content, without significantly affecting its physical morphology.

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 suggests that human keratin fiber matrix has a well-defined nano-scale grainy structure rather than being amorphous, with grain size influenced by chemical treatments, temperature, humidity, and follicle-level factors.

This study suggests that the absence of alpha5(IV)/alpha6(IV) chains in certain subepidermal basement membrane spots may relate to interactions with melanocytes in human skin.

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 while yak belly hair is chemically similar to human hair, its higher porosity and lower mechanical strength limit its usefulness as a substitute in hair dye development.
