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 for straight hair, friction mainly influences fragment formation during combing, suggesting no direct connection to tensile fatigue failure, while with textured hair, combing performance may be more complex.

This study reports that the candle flame technique "velaterapia," popular in Brazil for addressing split ends, can damage hair fibers due to bubble formation at high temperatures, despite thermal protectors providing some cuticle protection.

Different oils affect hair flexibility and strength, with their impact varying on whether hair is virgin or bleached.

This study found that in sheep, the microRNA oar-miR-377 regulates hair follicle development by targeting the SLC24A2 gene, and identified a genetic variation associated with wool quality, suggesting potential markers for breeding.

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 study concluded that the liquid chromatography-mass spectrometry method developed is viable for accurately quantifying spironolactone and its metabolite canrenone in plasma despite interference from plasma components.

This study developed a non-destructive X-ray fluorescence technique to quantitatively analyze elemental content in human hair and constructed a database of element concentrations in healthy Swedish, Caucasian individuals.

This article reviews dietary recommendations for managing polycystic ovary syndrome and provides evidence that diet changes can improve the androgen profile in affected women, but it reports no new clinical results.

This study suggests that chemical methods can reveal subtle differences in scalp hair color variability across populations and emphasizes the need for enhanced understanding of hair fiber curvature.

This article describes a case of late-onset focal dermal elastosis in a 73-year-old woman, characterized by flat pale yellow lesions and increased normal elastic fibers, distinct from pseudoxanthoma elasticum.

In this scoping review, researchers found that while some dietary approaches may help improve psoriasis symptoms—particularly in those with obesity or coeliac disease—the overall evidence is limited, and larger studies are necessary to identify effective diets for the broader psoriasis population.

This abstract outlines the historical development and medical validation of artificial hair implants, particularly the approval and improvement of the Biofibre® implant technique in Europe and Australia, and highlights its advantages as the latest advancement in hair restoration treatments.

This study found a significant positive correlation between hair thickness and growth rate, with a notably slower growth rate observed in men with male pattern hair loss compared to healthy controls.

This study found that melatonin administration effectively shortened the fur maturation period and altered hair follicle cycling in chinchillas.

This study found that treatments like abrasion, bleaching, and CETAB application affect hair fiber shear modulus differently, with moisture levels notably impacting bleached fibers more than untreated ones.

Hair coloring and bleaching can permanently break down hair protein and temporarily change its properties.

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 proposed a network model for the cross-linked structure of keratin-associated proteins in hair and wool fibers, suggesting notable differences between the two, potentially affecting hair fiber elasticity.

This study found that both dark and white dromedary camels exhibited high medullation in hair fibers, suggesting adaptations for insulation and heat dissipation in hot desert environments.

Atomic Force Microscopy is a more accurate way to assess hair damage and the effect of cosmetic treatments.

This study found that TRPA1-deficient mice exhibited normal cold sensitivity but had decreased mechanical response in nociceptors, suggesting TRPA1's role in mechanotransduction.

In this study, researchers found that disrupting the PRL gene in mice led to earlier hair molting, especially in females, suggesting that PRL inhibits murine hair cycle events.

This study suggests that a sandwich-structured wound dressing with bioceramic and polylactic acid layers may improve burn wound healing by absorbing exudates and promoting hair follicle regeneration.

This study found that grafting split-thickness human skin onto nude mice produces scars that mimic hypertrophic scar characteristics in humans, offering a useful model for studying scar formation and treatments.

In this study, higher expression levels of aromatase and steroidogenic acute regulatory protein were correlated with increased estrogen synthesis and fewer hair follicles in human skin, suggesting a link to elastic fiber formation and hair growth.

This study found that Florida manatees have unique types of specialized nerve endings in their vibrissae, which assist in their sensory and manipulative functions in aquatic environments.

This study suggests that age-related changes in skin elasticity reduce its stability against wrinkling, and anti-aging strategies should focus on addressing elastic mismatches between skin layers.

This study found that the moisture content of human hair significantly influences the type of fracture under tensile loading, with low or high humidity levels leading to smooth fractures and intermediate humidity resulting in step fractures.

This study suggests that human keratin fiber matrix has a well-defined nano-scale grainy structure rather than being amorphous, with grain size influenced by chemical treatments, temperature, humidity, and follicle-level factors.
