This study reported that the treatment of hair with glyoxylic acid straighteners causes major conformational changes within the hair fiber due to interactions between carbonyl and keratin components.

This study found that scanning electron microscopy revealed considerable abnormalities in hair morphology in MPS I, II, IIIA, and IIIB patients, potentially related to heparan sulfate accumulation.

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 a new 3D image analysis method from SEM images enables quick and accurate measurement of cuticle scale heights in hair fibers.

This review discusses in vitro methods for evaluating the effects of hair care products on hair fibers, reporting no new results; the authors emphasize the importance of selecting appropriate and accurate equipment for testing.

In this study, researchers developed a method using scalp cyanoacrylate biopsy and advanced imaging techniques to effectively measure and visualize the distribution of anti-dandruff shampoo ingredients zinc pyrithione and climbazole within the scalp follicular infundibulum.

This study reports the first cases of loose anagen hair syndrome in dark-skinned children from Upper Egypt, noting it may be under-diagnosed and primarily causes cosmetic concerns without affecting general health.

This study found that a new 12-point scale provided a more precise measurement system for evaluating hair damage and improvement after hair care product use compared to a 5-point scale.

This study found that using a high-viscosity, high-amine-content silicone fluid as a pretreatment can protect hair from bleaching and dyeing damage without affecting these processes.

This case report describes the first documented occurrence of pili torti in a healthy young adult cat, marked by noninflammatory and nonpruritic symmetrical multifocal alopecia.

This article outlines a protocol for scanning electron microscopy of murine skin and primary keratinocyte monolayers, providing a guide for sample preparation and examination.

This study found that plasma jets can effectively clean and oxidize human hair fibers, with argon/oxygen plasma having the strongest effects, suggesting potential as an alternative to peroxide treatment.

The study found that pili bifurcati causes hair to intermittently split into two branches, each with its own outer layer.

This study described a new wig coating technique using keratin and graphene oxide that significantly enhanced UV resistance, antistatic properties, and durability compared to traditional methods.

This study found that monoethanolamine-based hair color formulations caused significantly more damage to hair than ammonia-based formulations, especially at high concentrations.

This study found that medullary cell content in mammal hair evolves from an amorphous form to a biphasic phase, with human and anthropoid hair containing both macrofibrils and microfibrils.

In this study, grape seed oil was found to be the most effective herbal oil for improving gloss and reducing fractures in various hair types.

This study found that a microneedle patch using manganese thiophosphite showed greater hair regrowth potential compared to minoxidil, even with less frequent application, for treating androgenetic alopecia.

This study found that scanning electron microscopy can identify four specific hair morphology patterns in alopecia areata patients, offering a less invasive diagnostic option compared to punch biopsy.

This study reported that X-ray microscopy provides more intact images of hair's internal structure compared to transmission electron microscopy, particularly for observing fine details like cuticle coarsening and cortex cracks.

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

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 observed that different hair types on Tianzhu white yaks have similar ultrastructures, but coarse hair fibers show distinct structural differences across body parts.

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.

The document concludes that hair keratin-chitosan scaffolds were successfully made and are suitable for biomedical use.

In this study, researchers found that using 0.75% aspartic acid as an intermediate agent for a permanent wave improved wave formation and retention compared to a control in virgin hair, also reducing cuticle damage and maintaining tensile strength.

In this study, an infection model using rabbits was developed for dermatophytosis by inoculating macroconidia of Microsporum species, showing that direct intradermal application effectively progressed to the skin invasion phase and highlighted the correlation between severity of symptoms and duration post-inoculation.

This chapter reviews the anatomy and structure of hair, discusses hair damage and analyses, and explores methods for processing hair changes, but presents no new research findings.

This article provides a diagnostic guide for clinicians to differentiate between various hair shaft disorders by using a structured question-by-question approach but does not report new clinical findings.

This letter to the editor describes a case of acquired progressive kinking of the hair in a Korean female adolescent, but no new research findings are reported.
