In this study, researchers found that UV radiation causes hydroxy radicals to form cuticle holes specifically between the cuticle layers in wet hair, unlike random holes caused by Fenton's reaction.

This study describes the presence of holes in hair fibers, absent in hair follicles, likely forming from daily care actions and removal of extractable substances.

In this study, researchers found that chemical treatments like bleaching can cause severe damage to the hair cuticle, with previously modified hair showing complete deterioration compared to the partial degradation seen in virgin hair, highlighting the need for mindful cosmetic practices.

This study found that using an aqueous solution of AMPD in hair bleach reduced both hair damage and odor compared to ammonium hydroxide.

In this study, researchers found that a protein-enriched cream made from Spirulina platensis improved the physical structure of natural hair, as evidenced by more intact and smoother cuticles compared to a control cream without protein, suggesting its potential for hair care applications.

This study found that papain/bisulfite disintegrates human hair cuticles by dissolving the endocuticle, potentially accelerated by ethanol's removal of cell membrane material.

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.

Human hair's ability to get wet is complex and can change with treatments, damage, and environment.

This study found that applying a hair mist with dandelion extract before heat perming improved wave efficiency, tensile strength, and hair cuticle condition compared to a base mist or no pretreatment, demonstrating the extract's protective effects against heat damage.

The study developed a hair cream using extracts from plants like Hibiscus rosa sinensis and Nigella sativa, reporting that it may protect the scalp and hair by providing antimicrobial effects, promoting hair growth, and preventing hair fall and graying.

In this study, hair damaged by permanent dye showed signs of recovery over time, with near complete restoration to its original state after eight weeks.

This study found that keratin derivatives with functionalized thiol groups improved binding to both natural and bleached hair fibers, suggesting a promising strategy for enhancing keratin's durability in hair repair.

This study found that using henna dye positively affected hair cuticula pattern and diameters compared to undyed hair, though the degree of change may vary based on hair phenotype and condition prior to treatment.

This study found that chemical hair straightening significantly reduced hair curl and improved smoothness and shine, but did not significantly affect transverse fissures or split ends, indicating potential benefits with some side effects.

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

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.

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 article discusses how drug molecules integrate into hair fibers, focusing on biological transport mechanisms and physicochemical factors, but reports no new experimental findings.

This study reports that structural abnormalities in the inner root sheath of hair follicles may cause the hair shaft to be loosely attached in patients with loose anagen hair syndrome.

This review explores the structure and development of the hair cuticle, highlighting difficulties in studying some aspects and proposing new experimental approaches, but reports no new clinical results.

This review explains the mechanical composition and molecular interactions that determine hair's mechanical properties, without providing any new experimental findings.

This research examined the ultrastructure of deer hair fibers and found significant variations in diameter, cuticle thickness, and intermediate filament arrangements among different fiber types.

This study suggests that the cell membrane complex in hair cuticles contains hydrophilic regions with disulfide bonds allowing polymer uptake and hydrophobic lamella-like lipid layers.

This study reports a good correlation between the curvature of human eyelashes and the displacement of the neutral axis, influenced by the non-uniform thickness of the outer cuticle layer.

This article reviews the complex structure and molecular composition of hair keratins, highlighting their self-assembly process and implications for keratin extraction techniques, but reports no new experimental results.

This review discusses the causes of hair shaft abnormalities and highlights the role of cosmetic products in treating hair disorders, though it reports no new clinical findings.

This study utilized advanced imaging techniques to quantify hair damage and dye uptake dynamics, revealing that compound penetration in hair is influenced by molecule size and lipophilicity.

This abstract discusses the importance of physicians understanding hair disorders and their assessment, noting that homeopathic remedies have shown success in treating hair issues, allowing for tailored patient solutions within holistic medicine.

Pollution exposure speeds up hair damage.
