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 reports that some human cell surface HLA-I molecules (including HLA-B27) can appear without their usual peptide component, potentially altering immune interactions, influencing arthritis development in specific mice models, and exhibiting upregulation in certain cancer cells.

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.

Different hair types from various ethnic groups affect hair shine due to characteristics like thickness and shape.

This study found that UVB radiation primarily causes hair protein loss, while UVA radiation mainly contributes to hair color changes, with no significant differences in mechanical properties observed between photooxidized and non-irradiated hair.

This study analyzed how oxidative hair dye leaches from pigmented and nonpigmented hair during wash cycles, finding that melanin influences the dye deposition and leaching processes.

The authors concluded that their new grading system can effectively classify early female pattern hair loss and evaluate treatment progress.

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 found that the fungus Microsporum gypseum enzymatically degrades keratin in human hair, with the sequence of degradation reflecting the keratinization and cystine content of individual hair components in vitro.

This study developed a rapid, cost-effective three-dimensional skin equivalent model using human dermal fibroblasts, collagen, and hair follicles, which closely resembles natural human skin and can be used for autologous transplantation.

This study developed and validated a method for extracting cortisol from human and animal hair, suggesting its potential as a biomarker for assessing chronic stress exposure.

The conclusion is that a new method to measure hair shine was confirmed to match people's visual assessments.

This review explores the relationship between hair follicles and wound healing, emphasizing the importance of translating scientific findings into practical therapies for chronic wounds, but it reports no new experimental results.

This study validated a protocol for inducing surface ectoderm differentiation from human induced pluripotent stem cells and highlighted the role of TGFβ signaling pathways in this process.

This study showed that chemical and mechanical treatments significantly alter the nanoscale surface properties of hair, affecting its roughness, mechanical stiffness, adhesion, and surface potential.
