This study found that cysteic acid generation during hair bleaching is diffusion-controlled, increasing with the square root of bleaching time, in both cuticles and cortex of human hair fibers.

This study suggests that sebum samples can be effectively stored and transported with less stringent requirements than liquid samples, making them suitable for remote or at-home collection before clinical analysis.

This study found that the stability of the coiled-coil structure in human hair keratin is maintained by ion-pairing and hydrophobic interactions, which are disrupted as pH approaches 7.0.

This study identified multiple genetic variants in Pakistani families with oculocutaneous albinism, including two novel variants, enhancing understanding of its genetic basis and aiding better management and counseling.

This study found that a subfraction from Sansevieria trifasciata showed higher hair growth activity than other fractions in tests on rabbits.

This review discusses inflammatory and medication-related nephrocutaneous disease associations and emphasizes the importance of timely referral to nephrology for early management, but it reports no new clinical results.

This review covers the basic principles of forensic hair analysis, including how chemical substances get incorporated into hair, and emphasizes its applications in disease diagnosis, without providing new experimental results.

This study developed and validated a reliable method using chromatography and mass spectrometry to accurately measure finasteride levels in human plasma.

This study demonstrated that GP derivatization improves mass spectral analysis of spironolactone and its metabolites by reducing in-source fragmentation and enhancing signal clarity, laying the groundwork for future advancements in reaction optimization and quantitative assay development.

This study measured heavy metal concentrations in Hibiscus rosa-sinensis, Eclipta alba, and Solanum nigrum, finding that levels for Cu, Cr, Cd, Hg, As, and Pb were within WHO safe limits, suggesting these medicinal plant extracts are free from heavy metal toxicity concerns.

In this study, the authors concluded that a hydrolyzed eggwhite protein treatment promoted the reconnection of disulfide bonds in excessively bleached hair, after reduction and oxidation processes in permanent waving.

This study introduced and validated new spectrophotometric methods to simultaneously determine finasteride and tadalafil in Entadfi™ capsules with high sensitivity and without interference from excipients.

This study found that hair from ovarian teratomas shares similar chemical composition and morphology with scalp hair, but differs in physical properties and cysteic acid bands.

This study developed a precise and reliable UV spectrophotometric method for determining finasteride concentration in bulk and tablets, demonstrating strong linearity and accuracy.

This study observed that patients with autism spectrum disorder have a higher risk of developing alopecia areata compared to those without ASD, suggesting a possible link between the two conditions.

This report presents the early development of the Lupus Foundation of America's LFA-REAL™ patient-reported instrument, designed to enhance evaluation of lupus disease activity by combining patient and physician assessments.

This study found that Raman spectroscopy has potential for detecting biophysical differences in basal cell carcinoma compared to normal skin structures, supporting its future use in Mohs surgery.

This study developed and validated a UV spectrophotometric method for accurately measuring finasteride and tamsulosin in solutions and tablets, demonstrating good sensitivity and precision.

In this study conducted at a tertiary center in Yogyakarta, Indonesia, researchers evaluated pediatric hair and scalp disorders, finding that seborrheic dermatitis was the most common issue, particularly in infants, followed by bacterial and fungal infections among 545 patients under 18 years old.

This study found that visits for hair- and scalp-related disorders to a derm clinic increased significantly over a decade, with androgenetic alopecia showing the largest rise.

In this study, finasteride pretreatment led to EEG changes in rats that suggest a mild reduction in thioacetamide-induced hepatic encephalopathy.

This study introduced a noninvasive spectroscopy method to assess hair follicle stages in mice by measuring skin diffuse reflectance and melanin dynamics, offering a potential tool for hair regeneration research.

This study found that the optimal characteristics for ulin seed oil extraction are fresh, mature, and resinous seeds, and that FTIR spectrophotometry with PCA can effectively detect adulteration of the oil, particularly at certain wavenumbers like 1745 cm⁻¹.

This study observed that following hair transplantation, patients exhibited prominent perifollicular erythema and scaling one month after surgery, whereas by six months, accentuated follicular ostia and varying hair shaft abnormalities were consistently noted.

This study investigated the mechanical response of the human hair cuticle to strain and found that cuticular deformation directly corresponded with fiber elongation, revealing significant molecular-level changes in disulfide crosslinks but maintained structural stability, highlighting the role of the cuticle in stress resistance.

This study identified pathogenic or likely pathogenic gene variants in 70.1% of Russian families affected by hypohidrotic ectodermal dysplasia, expanding knowledge of causative mutations.

This study evaluated 386 patients with inborn errors of immunity and found that over half exhibited cutaneous, ocular, or hair manifestations, with bacterial skin infections and eczema being particularly prevalent. These findings may aid early diagnosis, especially in pediatric cases.

This study found that cis-urocanic acid can engage in non-enzymatic reactions with reactive sulphur species, forming new metabolites, and suggests sulphide donors may protect against UVB-related toxicity.

This study used a new multimolecular spectral method to uncover structural differences in hair keratin from individuals with androgenetic alopecia compared to healthy individuals, identifying potential biomarkers and providing insights for developing new treatments.

This study found that post-COVID syndrome symptoms persisted and were more common in individuals who had recovered from COVID-19 compared to uninfected controls in Kerala, though both groups showed significant symptom burdens.
