This study found that a blend of low- and high-molecular weight hyaluronic acid significantly improved penetration into the hair cortex compared to individual HA types, reducing frizz and increasing hair elasticity and water content, as measured by Confocal Raman Spectroscopy.

This study found that extensive cuticle damage from diperisophthalic acid oxidation did not alter the tensile properties of human hair, suggesting that these properties are mainly due to the cortex rather than the cuticle.

In this study, researchers found that hair fibers exposed to bleaching and UV irradiation displayed significantly more damage, including increased adhesion and surface heterogeneity, compared to untreated hair, highlighting a synergistic degradation pathway affecting the hair cuticle's integrity.

Twisting hair weakens it, but strength can be recovered at low twist levels.

This study found that shikimic acid- and maleate-based hair repair agents modified the structure of hair fibers, though they did not increase disulfide bridge content in the hair cortex.

In this study, researchers used scanning electron microscopy to analyze hair damage from 3% hydrogen peroxide and UVB radiation, observing that Caesalpinia sappan hair tonic formulations coated and interacted with the hair cuticle, potentially modifying hair fiber damage.

This paper discusses the use of Digital Volumetric Imaging with fluorescent dyes to visualize and compare the interior structures of six different virgin hair types, reporting no new clinical results.

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.

This study compared shampoos and found that shampoo D, containing polyquaternium-10, guar gum, and dimethicone, was most effective in restoring chemically permed hair.

This study observed that mice with a Cx43 mutation exhibited slower and asynchronous hair regrowth with severe cuticle weathering, mimicking aspects of hair phenotype in some ODDD patients.

This study found that repeated exposure to ozonated water caused oxidative changes in hair proteins, lipids, and pigments, leading to altered hair properties, with minimal effects on shine and color.

This review examines the chemical composition and potential health risks of hair straighteners, but it reports no new findings and emphasizes the importance of understanding hair fibre structure for safe use.

Hair styling products can damage hair over time.

This study used nanoscale secondary ion mass spectrometry to locate where calcium and copper are concentrated in colored hair, finding these metals particularly in the cuticle's sulfur-rich regions.

This article proposes a methodology for selecting hair extension technology that aligns with natural hair structure and aesthetic goals, suggesting the best results are achieved by matching technique to hair's mechanical capacity.

This study reviews the biology and cosmetic treatment of hair, emphasizing future advancements in safer, more effective procedures to meet consumer needs for hair care.

This review discusses the impact of various exogenous agents on hair, such as cosmetics and radiation, but reports no new experimental results.

This study reported that albino Wistar rats exposed to chemical hair straighteners showed significant hair fiber damage and scalp skin deterioration, which worsened with repeated and prolonged application, highlighting the cytotoxic potential of these products and potential systemic risks.

This study found that pretreatment with KP-Cryst fusion proteins effectively protected Asian and Caucasian virgin hair from thermal damage by maintaining higher water content and preventing structural changes during heat application.

This review examines the pH levels of various shampoos and reports no new clinical results, highlighting the potential importance of labeling pH values on shampoo packaging for hair and scalp health.

This study conducted in situ tensile loading experiments with atomic force microscopy to observe how conditioning treatments affect the tensile response of virgin, chemically damaged, and mechanically damaged Caucasian hair.

This study reports on the biochemical characteristics of S100A3 protein in human hair cuticle, notably finding its N-terminal methionine is acetylated and has a slightly lower isoelectric point compared to the recombinant version.

This study found that sodium metabisulfite activates sodium channels and increases cellular excitability and excitotoxicity in both cardiomyocyte and neuron models, which exacerbates seizures and neuronal damage in rats.

This study found that the novel dot-block method can effectively measure early- and advanced-glycation products in hair, suggesting its potential for monitoring diabetes progression and other chronic conditions.

This paper discusses various histologic features to distinguish types of alopecia and reports no new clinical findings.

This research focuses on Milagros's strategy to internationalize by exporting their intensive repair hair mask to Mexico, France, and the United States, examining each market's potential and challenges in the global hair care sector.

This article reviews the components and forms of hair styling aids, their safety, and potential use in improving appearance-related hair conditions but reports no new clinical findings.

This study found that high-power millimeter wave exposure can cause skin injury in mice, with the severity of damage correlating to the duration of radiation.

This review discusses the complex mechanisms behind acne vulgaris and suggests that dietary modification, along with pro- and prebiotics, may influence its pathogenesis by addressing stress-induced skin inflammation.

This review discusses the potential skin care benefits of non-denatured soybean extracts, including skin lightening and UV protection, but reports no clinical results.
