This study demonstrates that a newly developed bio-based, dual-phasic hair serum offers a sustainable and effective alternative to traditional silicone-based serums, enhancing hair cuticle integrity and consumer appeal while supporting environmentally friendly formulation design.

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.

This study evaluated a hair mask containing rice germ oil GX-N and ferulic acid on damaged hair and found that rice germ oil GX-N improved hair characteristics after bleaching, UV, and heat exposure, but adding ferulic acid did not provide extra benefits.

In this study, a bleaching protocol was developed to evaluate hair repair products, revealing that K18® and Olaplex® improve hair brightness and lightness, with distinct impacts on hair fiber properties.

In this study, a 3-year-old Japanese child with autosomal recessive woolly hair was found to have a distinctive irregular and rough cuticle on the hair shaft, along with a homozygous pathogenic LIPH variant, suggesting a critical role for genetic analysis in understanding rare hair conditions.

This study presented a case of tinea capitis in a 4-year-old without typical symptoms and traced the infection to Microsporum canis carried by domestic cats, highlighting the need for accurate diagnosis and appropriate treatment, especially in households with pets.

In this study, researchers examined juglone's potential as a restoring agent for hair keratin damaged by permanent or bleaching treatments, finding that juglone formed Michael adducts with cysteine residues, leading to a more regular hair surface as observed via IR spectroscopy and SEM analysis.

This study identified new geometric and mechanical parameters for curly and kinky/coily hair, which may inform more effective personal care products tailored to these hair types.

This study used quantitative methods to identify new geometric and mechanical parameters of curly and kinky/coily hair, aiming to improve classification and develop better personal care products for these hair types.

This study found that scanning electron microscopy revealed significant hair shaft changes in women using straighteners, but not in those using hair dye, suggesting its utility in assessing chemical treatment effects on hair.

Hair shaft malformation contributes to Central Centrifugal Cicatricial Alopecia.

This study found that hair follicle stem cells can proliferate and differentiate into keratinocytes on chitosan skin-engineered templates, suggesting potential applications in regenerative medicine.

This chapter reviews hair anatomy, hair shaft structure, and various cosmetic treatments that can alter or damage hair, but it presents no new research findings.

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

This review updates on various methods for hair and scalp examination, encompassing non-invasive, semi-invasive, and invasive techniques, and reports no new results.

This study found that using ionic liquid for specimen preparation allowed for observation of dermal papilla cells and their cilia in near-living conditions, reducing damage typically caused by conventional preparation methods.

This review discusses the use of hair microscopy in diagnosing hair-related conditions, highlighting techniques and common applications, but presents no new experimental results.

This study found that milk protein grafting and cross-linking treatment significantly improved the pilling resistance of rabbit hair knitted fabric.

The demineralized bone matrix scaffold is better for cell attachment than the mineralized bone allograft.

This study found that Indian and Chinese black hair, with higher melanin content, resist photochemical degradation better than European hair, which has lower melanin levels, when exposed to dry, hot climates.

This study found that treating yak hair fibers with low-temperature plasma and microwaves weakened the scale structure and significantly improved dyeability.

Polymethylene wax in hair relaxers makes hair smooth and shiny with less damage.

In this study, researchers developed an environmentally friendly hair coating from casein proteins and tannic acid, enhancing the tensile strength of virgin Asian hair by approximately 21% compared to untreated hair, while maintaining elasticity.

This study found that using 369LAB Lipid Bond, derived from plant oil triglycerides, can restore lipid content in damaged hair to natural levels and improve hair strength, integrity, and resilience after a single application, with benefits persisting even after discontinuation.

This in-vitro study reported that a luliconazole-based formulation improved hair cuticle integrity and was more effective than ketoconazole in repairing damaged hair after 5 and 10 washes, with sensory analysis supporting these results. Further human studies are needed to confirm its clinical effects.

This study found that a fibroin-based cosmetic ingredient improved the mechanical properties and cuticle repair of African-American and Caucasian hair types, even when damaged by chemical treatments.

This study found that a fermented mixture containing Sasa Borealis leaf improved tensile strength and glossiness in hair damaged by heat perm and dyeing, suggesting potential as a cosmetic ingredient.

This study found that a sucrose-based crosslinker can effectively straighten hair and maintain durability in high humidity and through repeated washings without affecting the hair's tensile properties or causing surface damage.

This study found that using a hair-hardener improved hair thickness, amino acid content, surface condition, tensile strength, and wave efficiency without causing any allergic reactions in participants.

Lower acetylation makes chitin nanofibers thinner and more suitable for various uses.
