This study found that two pre-Hispanic mummies from the Andean coast had well-preserved hair with significant amounts of heavy metals like iron, lead, bromide, and occasionally arsenic, revealing their historical context.

This study identified a strong association between heavy metal contamination in drinking water and chronic diseases like renal failure and liver cirrhosis in Great Cairo Cities, Egypt.

In this study, researchers identified two potential urinary biomarkers, testosterone–glucuronide and 11α-hydroxyprogesterone, along with four candidate biomarkers, to help understand and diagnose polycystic ovary syndrome.

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 found that anti-Müllerian hormone (AMH) showed high sensitivity and specificity as a diagnostic marker for polycystic ovary syndrome in the studied population, suggesting its promise as an objective diagnostic tool.

In this case study, authors reported that a 43-year-old female patient initially showed persistently high testosterone levels due to immunoassay interference, later verified as normal using liquid chromatography-tandem mass spectrometry (LC-MS/MS), highlighting the need to consider assay artifacts in diagnosing hyperandrogenism without clinical signs.

In this study, oxidation hair dye formulations tested on mice showed no evidence of causing systemic toxicity or cancer over an 18-month period.

This study found that cutaneous pyridoxal 5'-phosphate hydrolase activity may be carried out by an enzyme different from the classical tissue-nonspecific alkaline phosphatase in human and mouse skin.

This study developed a new analytical method to identify a wide range of endocrine disrupting compounds in full-term amniotic fluid, revealing diverse substances with potential endocrine activity.

This study found that two-thirds of patients with persistent chronic daily headache showed significant improvement with divalproex sodium treatment, although common side effects included weight gain, tremor, hair loss, and nausea.

This study found that alkali bromide solutions are absorbed into hair depending on salt activity, and the presence of the salt increases water absorption compared to normal conditions.

This study demonstrated that the differential wetting characterization (DWC) method can effectively differentiate changes in the wetting properties of hair fibers after chemical or physical treatment.

This reprint reviews 14 papers on advances in solid-phase microextraction techniques for bioanalysis, reporting no new results.

This study found that using an aqueous solution of AMPD in hair bleach reduced both hair damage and odor compared to ammonium hydroxide.

This study observed that amelanotic melanocytes from human hair follicles appeared morphologically immature, suggesting they might not transfer melanosomes into keratinocytes.

This study developed and validated a simple, cost-effective UV–Visible spectrophotometric method for estimating finasteride in pharmaceuticals, demonstrating good linearity, accuracy, precision, and sensitivity according to ICH guidelines, making it suitable for routine quality control.

This study describes a new method using high-resolution mass spectrometry for analyzing multiple steroids in human scalp hair, with newborn hair showing the highest steroid concentrations among examined age groups.

This study reported that Gagamchengyoung-tang may reduce scalp disorder and increase hair density in alopecia patients with a febrile tendency.

This study observed very high thallium levels in small mammals near a zinc smelter in Poland, accompanied by severe population and health impacts.

This study found that high molybdenum levels in the diet, especially with added sulfate sulfur, led to symptoms like alopecia and hair color loss in heifers; however, these were corrected by adding copper.

Minoxidil is a new drug that lowers blood pressure.

This study found that hair coloring, waving, and ironing were associated with increased hair abnormalities compared to untreated hair in Iranian women.

This review outlines the factors affecting skin greasiness and sebum production, highlighting measurement challenges but reports no new clinical findings; further research may guide sebosuppressive treatments for acne.

This study explored the use of manganese-doped calcium silicate nanowire-incorporated alginate hydrogels (MCSA hydrogels) for treating melanoma and promoting wound healing, finding that these hydrogels effectively ablate melanoma under near-infrared irradiation and enhance vascular endothelial cell activity for tissue regeneration.

In this study, researchers used atomic force microscopy to capture and analyze morphological changes in the surface of healthy hair, identifying features such as pitting and rod-shaped macro-fibrillar elements, which could inform future research on hair conditions and care.

Hair dye with para-phenylenediamine can cause skin depigmentation.

This study found that the structure and mineral content of dromedary camel hair, specifically the medulla patterns, medulla index, and elemental composition, change with age, revealing differences among camels aged 1 year, 3-5 years, and 8-10 years.

This study suggests that ischemia-modified albumin may play a role in premature hair graying and vasogenic erectile dysfunction, potentially serving as indicators of susceptibility and severity.
