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

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.

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.

Curly and straight hair differ in how their internal fibers are arranged.

This study found that treating hair with ATS, formed from fumaric acid and cysteamine, effectively improved hair quality by increasing moisture content and altering the internal structure of strong curls.

This study concluded that the curliness of human hair, regardless of ethnicity, originates from the inhomogeneous internal nanostructure due to differences in the distribution of two types of cortices.

This study found that chemically treated hair, particularly when subjected to both acid straightening and bleaching, experiences more significant structural damage when exposed to heat, highlighting key changes in both the internal and surface components of hair fibers.

Light scatters differently from elliptical hair fibers than from circular ones, and a new model better predicts this behavior, especially for shiny highlights.

A new method helps understand hair shine and various products improve hair care.

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 alkali bromide solutions are absorbed into hair depending on salt activity, and the presence of the salt increases water absorption compared to normal conditions.

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.

This study investigated various proteins as eco-friendly hair perming agents for Asian hair and found that bovine serum albumin and keratin achieved perming results comparable to commercial products, while also increasing hair moisture, indicating a protective effect during heat styling.

This study found that shampoo and conditioner do not alter hair's molecular structure, while perming treatments significantly affect keratin and intermediate filament structures due to bond alterations.

This study found significant structural and compositional differences in hair affected by alopecia areata compared to healthy hair, using a range of physico-chemical investigation methods.

This study found that washing hair with surfactants reduces the internal density of hair due to cuticle lifting, and suggests that a cuticle-sealing strategy can inhibit this effect and maintain hair homeostasis.

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.

The document describes various skin conditions, their features, and treatments but lacks detailed study size information.

This systematic review found that treatments for sickle cell disease-related priapism are clinically diverse, with etilefrine, pseudoephedrine/etilefrine-5 inhibitors, and finasteride appearing promising, but further research with robust study designs is needed to establish evidence-based practices.

This study found that while molecular hair structures were nearly identical across individuals, genetic factors seem to influence specific lipid compositions, as seen in identical-patterned hair from parent-child pairs and identical twins, but not fraternal twins.

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.

In this study, researchers found that the lipid composition in hair significantly affects water diffusion and may explain differences in dyeing and cosmetic treatment responses between Asian and European hair, with CP2 fibers having more lipids than CP3 fibers.

This review discusses the applications and challenges of lipid nanosystems in various fields, comparing techniques for evaluating nanoparticle properties, and reports no new experimental results.

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.

This study found that Muse cells retained their pluripotency and ability to differentiate into various cell types even after being cryopreserved multiple times.

In this study, researchers used tissue clearing techniques on human skin and scar tissue for the first time to render them optically transparent, with the aim of revealing atypical structures and improving protocols for observing scar tissue changes.

Non-white organ transplant patients have worse skin cancer outcomes due to later diagnosis and treatment.

This study found that centrosomes, unlike cilia, are essential for proper epidermal and hair follicle development in mice, with these effects being dependent on the presence of p53.

This case report describes the first known instance of dermatomyositis-related panniculitis in the neck and mediastinal region, effectively treated with corticosteroids, dapsone, and colchicine.
