This study investigated the effects of ammonium thioglycolate and amino methylpropanol hair straightening followed by permanent coloring, finding significant physical and chemical changes to both the cuticle and cortex of hair fibers.

A specific gene mutation is linked to a hereditary form of dystonia that responds well to certain medications.

This study found that the majority of "hypoallergenic" hair dyes still triggered allergic reactions in patients sensitive to para-phenylenediamine.

This study proposes a new clinical scoring method for hair density based on hair diameter diversity, which correlates with existing measures and reflects follicle miniaturization in androgenetic alopecia.

This study identified novel mutations in the DSG4 gene in a Japanese patient with monilethrix, affecting protein interactions that may disrupt hair shaft structure.

This study found that 1,2,3,4-tetrahydroquinoline derivatives, particularly N-methyl-7-amino-1,2,3,4-tetrahydroquinoline, may be excellent blue dye candidates for human hair, offering superior color purity, stability, and fastness compared to 2,3-dihydroindoles.

This study reported that certain minoxidil conjugates, specifically those with spermine, methylenedianiline, and diaminofluorene, were able to induce differentiation in HL-60 acute myeloid leukemia cells without toxicity at a concentration of 10 μM.

This study found that X-irradiation causes hair dysplasia through two mechanisms influenced by oxygen, and cystamine injections after irradiation enhance this effect.

A dissolving microneedle patch with dutasteride offers effective, long-lasting hair loss treatment with fewer side effects.

This study found that scanning electron microscopy revealed significant hair shaft changes in women using straighteners, but not in those using hair dye, suggesting its utility in assessing chemical treatment effects on hair.

This study found that many women aged 40 to 65 in urban Bangalore have magnesium intake below recommended levels, with symptoms like hair loss and muscle cramps being widespread.

This article provides an overview of hair density, hair diameter, and the prevalence of female pattern hair loss but reports no new clinical findings.

This study found that cadmium adsorption on human hair varies significantly between individuals, likely due to differences in hair acidity, and nearly complete removal can be achieved with strong acid solutions.

This study reported a decrease in zinc and iron levels in the blood and an increase in certain trace elements in hair among patients with alopecia areata compared to healthy individuals.

This study found that Dex-loaded hyaluronic acid hydrogel microneedles significantly reduced pain in an acute inflammatory visceral pain model without sedation, suggesting a promising and patient-friendly alternative to intravenous delivery.

This case highlights the potential link between type 1 diabetes, pernicious anemia, and alopecia areata universalis, suggesting clinicians should monitor for pernicious anemia in such patients.

This study found that dimethylpabamidopropyl laurdimonium tosylate, a quaternary ammonium surfactant, adsorbs onto human scalp hair with kinetic and isotherm behaviors fitting specific models, changing hair fiber wettability from hydrophobic to hydrophilic.

In this study, researchers examined the methylation patterns in the skin tissues of Alpine Merino sheep with varying wool fiber diameters, finding that specific methylated RNAs linked to the Wnt, Notch, and TGF-ẞ signaling pathways may influence fiber diameter and potentially improve wool quality.

This study found that repeated oral intake of 0.5 or 5 mg/kg of cobalt ferrite nanoparticles induced pulmonary toxicity in rats, with dose-dependent oxidative stress and inflammation observed, but no notable toxicity was seen at a 0.05 mg/kg dose.

This study discovered that minoxidil affects hematopoiesis by downregulating wnt4, leading to suppression of hematopoietic stem and progenitor cells and alleviating MDS-like symptoms in zebrafish and mice, with hematologic safety achieved at optimized doses.

Tiger tail banding and hair abnormalities are reliable indicators for diagnosing trichothiodystrophy.

This study reports that adjusting the valence states of Mo in Pluronic F127-coated MoO3-x nanozymes enhances their selective H2O2-related catalytic activity, showing promise in acute kidney injury treatment and enabling real-time monitoring of therapy effectiveness through ROS-responsive photoacoustic imaging.

In this study, researchers created a new molecular salt from minoxidil and 2,4-dihydroxybenzoic acid, finding it superior to raw minoxidil for promoting hair growth in a mouse model, suggesting it may be a promising candidate for treating hair loss.

This study observed an association between body iron levels and non-scarring diffuse hair loss in non-menopausal women.

This case report suggests that nonsynchronized segmented heterochromia in black scalp hair in a 14-year-old girl may represent premature greying unrelated to deficiencies in iron, copper, zinc, or protein.

This study found that reduced plasma DIAPH1 levels were associated with polycystic ovary syndrome, suggesting DIAPH1 as a potential predictive factor for the condition.

This study found that women with diffuse alopecia exhibited deficiencies in several trace elements, including sulfur, iron, and potassium, while men showed deficiencies in calcium, sulfur, and zinc.
