In this study, researchers found that the primary cause of slippage and detachment of keratin capsules in hair extensions is the re-contamination by oily residues from the hairdresser's hands, rather than the use of hair care products like masks or conditioners.

This study found that straight permed hair retains more weight than virgin hair during burning at higher temperatures, with distinct differences in morphological changes observed through thermal analysis and microscopy.

This study found that the HairCheck® device, demonstrating high correlation between its Hair Mass Index and hair characteristics such as strand number and diameter, may be an effective tool for assessing hair mass changes in alopecia patients.

In this study, researchers found that a combination of celery and candlenut extracts significantly increased hair length in male Wistar rats, while hair weight increased with either extract alone or combined, and hair thickness was most improved with candlenut extract alone.

In this study, researchers developed a method called the Stiffness-Angle Law and found that hair treated with caffeine-infused shampoo showed a 13.2% increase in stiffness, as measured by their novel evaluation technique.

This study found that transient mtDNA double strand breaks in mice accelerated aging in certain tissues through increased reactive oxygen species, independent of p21/p53 pathway mediation.

This study found that female students aged 18-21 with PCOS had higher weight compared to those without, though their BMI remained in the normal range.

In this study, mozuku-derived ultra-high-molecular-weight fucoidan was found to inhibit the growth of skin bacteria like Staphylococcus aureus but not other tested bacteria such as Cutibacterium acnes.

This review evaluates hair growth measurement methods for human scalp hair, suggesting that combining highly resolutive analytical approaches with global calibrated methods is recommended for assessing hair changes in clinical settings.

This article reviews the diagnostic process for hair problems, emphasizing the importance of thorough patient evaluation and communication but reports no new clinical results.

This review discusses the evolution of diagnostic criteria for polycystic ovary syndrome and emphasizes its association with various metabolic and cardiovascular risks, but it provides no new research findings.

This abstract explains that androgenetic alopecia, a common hair loss disorder influenced by genetics and hormones like dihydrotestosterone, has FDA-approved treatments including minoxidil, finasteride, and photolaser therapy, but its genetic basis and susceptibility to environmental factors remain complex.

This review discusses oxidative stress's role in polycystic ovary syndrome and examines various biomarkers to understand its impact on the disorder's pathogenesis, but reports no new clinical results.

Hair extensions can cause hair loss and scalp damage, and these problems might be more common than people realize.

This review discusses in vitro methods for evaluating the effects of hair care products on hair fibers, reporting no new results; the authors emphasize the importance of selecting appropriate and accurate equipment for testing.

This study found that metabolite levels in hair samples differ significantly by hair color and segment, leading to recommendations for best practices in hair metabolomic studies.

This article discusses the diagnostic complexities of PCOS and emphasizes the importance of differentiating between polycystic ovaries and polycystic ovary syndrome; it presents no new experimental results.

In this study, WNT10A was identified as a key gene in the development and maturation of skin hair follicles in fetal Inner Mongolian cashmere goats.

This review summarizes evidence indicating that body image issues in patients with systemic lupus erythematosus should be addressed with the same importance as physical symptoms like pain and disability.

This study examined the prevalence and management of PCOD, finding that it primarily affects unmarried women aged 18-25, causing symptoms like irregular periods and infertility, with many opting for medication and lifestyle changes despite mixed beliefs about their effectiveness.

This study found that low-molecular-weight hyaluronate significantly improved the mechanical strength and elastic modulus of overbleached hair by enhancing hydrogen bond networks within keratin.

This chapter reviews the perioperative management and evaluation processes for bariatric surgery, emphasizing candidate selection, surgical risk reduction, and optimizing outcomes, and reports no new clinical results.

This article provides a clinical Q&A on bariatric nursing and surgical patient care and reports no new research findings.

This study examines various methodological factors affecting hair cortisol concentration analysis, finding inconsistent results on the impact of factors like resuspension solution, hair weight, extraction duration, and hair-cutting method.

This study found that ponytails with small fractions of gray hair have significantly lower swing height and higher damping, affecting the dynamic movement and appearance compared to those with fewer gray hairs.

This study explored 25-hydroxyvitamin D3 levels in hair samples from participants in Aberdeen and suggested potential links between hair vitamin D levels, seasonal UVB exposure, and marine diet in both modern and archaeological contexts.

This study found that CRISPR/Cas9-induced loss-of-function mutations in the FGF5 gene significantly increased wool length and yield in genetically modified Chinese Merino sheep compared to wild-type controls.

This review examines the role of oxidative stress in male hypogonadism associated with noncommunicable chronic diseases and discusses various management strategies, but it presents no new clinical findings.

This study found that modern styling cosmetics can significantly alter hair structure through changes in interfacial chemistry and cohesion, particularly when applied to already damaged hair.

This model study describes how interactions between hair keratin and various materials alter hair's physical and mechanical properties by affecting noncovalent bonds.
