This study observed that repeated perm treatments decrease disulfide bonds in hair due to their conversion largely into cysteic acid, affecting the waving efficiency depending on the reduction agent used.

This abstract presents a case of arsenical dermatitis with pigmentation and alopecia developed during treatment with arsphenamine for a positive Wassermann reaction.

This study reports that Lef1 plays a crucial role in promoting bulge stem cell differentiation towards hair fate by activating β-catenin and downstream signaling pathways during hair follicle development.

This study revealed significant signals of drug-related cognitive disorders in several medications that lack relevant FDA label warnings, suggesting a need for increased clinical awareness and potential label updates.

This study found no evidence supporting the hypothesis that Aβ afferents sprout into the superficial laminas of the spinal cord after nerve injury in rats.

In this study, researchers observed the patterns of hair distribution and scalp anatomy in Chinese young adult males, finding significant variations in hairline shape, hair density, and follicular unit structure.

This study demonstrates that spatially resolved IR and Raman imaging can effectively reveal the molecular structure and composition of untreated human hair, providing insights into its chemistry and structural integrity.

The guideline recommends mental health involvement in diagnosing gender identity disorder and outlines hormone and surgical treatment protocols, emphasizing safety, informed consent, and long-term monitoring.

This article discusses the structure of hair follicles and their significance in evaluating hair disorders, but it does not report any new research findings.

This review discusses gender identity disorder in Japan, highlighting the high prevalence and challenges in accessing appropriate treatment, and calls for wider understanding among medical professionals.

This review discusses the classification and diagnosis of primary scalp alopecia, focusing on scarring and non-scarring types, and reports no new clinical results; it emphasizes simplified diagnostic pathways and tissue processing techniques.

The document explains how hair follicles develop, their structure, and how they grow.

This study highlights the importance of understanding the rheological properties of hyaluronic acid fillers, including viscosity, cross-linking, and concentration, to optimize their use in addressing facial aging by maximizing clinical effects.

In this study on tolerant rats, maternal and developmental toxicity from levo-alpha-acetyhnethadol hydrochloride were observed at all doses, without specific fetal toxicity or teratogenic effects.

Examining scalp biopsies in different ways helps better diagnose hair loss types.

This article reviews various hair transplant techniques and procedures across different ethnic groups but does not provide new clinical results, highlighting the need for tailored approaches in diverse populations.

In this case report, a 31-year-old man with frontal hairline recession saw a marked improvement in hair density and scalp appearance after undergoing six mesotherapy sessions alongside twice-daily application of 5% minoxidil, attributed to the treatment protocol combining nutrients, bioactives, and topical minoxidil.

This study found that scanning electron microscopy can identify four specific hair morphology patterns in alopecia areata patients, offering a less invasive diagnostic option compared to punch biopsy.

This article examines differences in aging among ethnic populations and highlights cosmetic procedures specific to skin of color, but reports no new research findings.

This study found that the mechanical stiffening of the human hair follicle along the first millimeter is linked to changes in the keratin network architecture and composition during keratinization.

This study found that ARHGEF3 is crucial for hair follicle development in mice, as its absence leads to defects in placode compaction and impaired follicle downgrowth, highlighting its role in regulating cell shape rearrangements during embryogenesis.

In this study, high doses of Lepidium sativum seeds extract were reported to cause toxicity and tissue damage in animals, suggesting the need for careful use under medical supervision.

This study identified the dermal sheath as a key component of the hair follicle niche, essential for outer root sheath regression during the hair cycle, highlighting its importance in hair follicle support and regulation.

This study developed granular hydrogels with reversible interparticle cross-linking, finding they offer high mechanical stability and enhance cell recruitment, making them promising for injectable and 3D printable scaffolds in tissue engineering and therapeutic delivery.

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.

Hair shape is determined by genetic, molecular, and cellular factors.

In this case-control study, researchers observed that smoking and lighter hair color significantly increased the risk of developing androgenetic alopecia, with older individuals and women showing higher prevalence rates, while hair thickness and shape were not linked to increased alopecia risk.

This study found that novel thiol-reactive cross-linking agents, particularly APA, significantly improved the tensile strength and elasticity of human hair fibers by effectively regenerating disulfide bridges, with potential applications for advanced hair repair treatments in the cosmetic industry.

This review discusses how immune mechanisms contribute to the regeneration and repair of epithelial tissues and highlights their potential role in both disease and therapeutic innovation; it reports no new clinical results.

This study found that a novel cross-linked hyaluronic acid dermal filler is safe and effective for improving lip enhancement, cheekbone augmentation, and nasolabial folds across different skin types, with significant improvements in wrinkle severity and overall facial aesthetics observed.
