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 found that sensor-controlled scalp cooling prevented visible hair loss in 53% of breast cancer patients undergoing chemotherapy, with greater hair density and absence of comorbidities enhancing its efficacy, also improving patients' quality of life without increasing scalp metastasis risk.

In this study, researchers highlighted that while hair lipids are crucial for hair health and protection, surfactants in shampoos and conditioners can partially remove these lipids, potentially affecting hair structure, though the exact mechanisms remain poorly understood and require further investigation.

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 review discusses the development and future prospects of biomaterials for in situ tissue regeneration but reports no new research results; it underscores the importance of biomaterials in addressing tissue defects.

This review discusses the challenges and contradictions in understanding nanoparticle penetration and toxicity in human skin, emphasizing the need for standardized testing and further research on particles smaller than 10 nm.

This study observed that daily selenium sulfide shampoos successfully removed fungal spores hidden beneath the hair cuticle in patients infected with ectothrix Microsporum canis.

This study suggests that a hair dye formulated with nano-sized Calendula Officinalis extract can effectively color white hair and lighten black hair, offering an alternative to synthetic dyes.

This study reviewed chitosan composites, specifically those with silver or zinc oxide nanoparticles, highlighting their enhanced antimicrobial efficacy and potential biomedical applications despite pure chitosan's limitations such as pH sensitivity and poor solubility.

This study demonstrated that a light-activated RNAi approach using hollow gold nanoshells effectively targets human prostate cancer cells with reduced off-target toxicity and material use compared to standard methods.

This study found 100% efficacy in treating psoroptosis in sheep and wild goats using macrolide injections "Iveron-10" and "Dectomax," complemented by "Butox-50" bathing in sheep, though infestation initially affected all animals with varied severity.

This study investigated the effects of wool-derived hydrolysed keratin peptides on relaxed textured hair and found that mid- and high-molecular weight peptides improved mechanical strength and reduced breakage in different humidity conditions.

This review discusses nanoparticle systems for cancer treatment and reports no new clinical results; the authors emphasize their potential to reduce systemic toxicity and call for further development.

This article discusses surgical treatments for male pattern hair loss in black individuals, emphasizing the need for technique adjustments due to specific characteristics of black skin and hair, but reports no new clinical results.

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 observed that treating human hair with NaOH led to partially removed cuticles, resulting in better fiber cohesion and mechanical properties similar to wool, unlike bleach or formic acid treatments, which weakened the fibers.

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 transplanting human hair follicle pluripotent stem cells can promote the recovery of sciatic nerve function in a mouse model of nerve impingement.

This study found that mackerel fermented fish oil protected human keratinocyte cells from UVB-induced oxidative stress by scavenging free radicals and reducing cellular damage.

This study found that ultraviolet radiation negatively affects hair follicle functions in human scalp skin, and caffeine application may provide some protective effects against this damage.

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 study found that after four weeks of daily use, the roughness of the hair surface significantly decreased, as shown through quantitative image analysis using HIROX.

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 investigated lipid loss in hair caused by surfactants and found that surface and internal modifications can significantly protect different lipids from depletion, with internal modification preventing 52.0 to 81.3% of lipids in certain groups.

This study proposes a simple fluorescence method to evaluate hair damage and protection, suggesting that emissive properties of hair can aid in substantiating cosmetic claims.

This study compared the effects of three compounds on structural and sensory benefits for bleached hair when applied with or after bleaching, observing that their application may mitigate bleaching-induced damage.

This study found that thermal hair-straightening devices significantly damaged the cuticle and cortex of virgin Asian and Caucasian hair, with Asian hair experiencing more protein loss than Caucasian hair.

This study found that hair proteome profiling and genetically variant peptide identification in hairs remained effective after an explosive blast, indicating potential for forensic human identification despite damage.

This chapter provides an overview of the complex chemical and physical structure of the hair surface, detailing how factors like ethnicity, environmental stress, and cosmetic treatments can alter its properties and influence the adhesion of hair care products.

This article reviews the role of skin surface lipid in mediating environmental stressors and discusses potential therapeutic interventions, reporting no new experimental findings.
