This study found that fentanyl accumulates differently in mouse hair after systemic administration compared to external loading, suggesting ionizable functionalities of hair influence drug retention from organic solutions.

This research suggests that both proposed pathways into hair fibers for molecule penetration are valid and complementary, with all fiber structures acting as potential routes for delivering materials.

This article discusses a study linking tamsulosin treatment for benign prostatic hyperplasia to a small but statistically significant increase in dementia risk compared to other treatments, without presenting new results.

This clinical study found that a three-month Ayurvedic leave-on treatment significantly improved hair density and reduced hair fall in healthy Indian adults experiencing hair loss, with efficacy supported by increased VEGF expression in dermal papilla cells, promoting follicular angiogenesis.

This study used molecular docking to analyze nine compounds from the Siddha herbal formulation Kushtakudori ennai, finding that they may effectively interact with androgen receptors to hinder hair follicle shrinkage and potentially reduce hair loss, showing potential as anti-alopecia treatments.

In this study, the researchers found that measuring tacrolimus levels in scalp hair could be a reliable method for monitoring drug exposure in kidney transplant recipients, offering an alternative to frequent blood tests by utilizing self-collected hair samples.

The research investigated the effects of antiandrogens on neurodevelopmental milestones in rats exposed to valproic acid during pregnancy, finding that while valproic acid delayed sensorimotor reflexes, it didn't impact physical development milestones, and antiandrogens partially mitigated these delays.

This study reported no measurable effect on libido or other sexual life parameters in finasteride users compared to non-users among male participants examined with the Arizona Sexual Experience scale.

In this study, the authors developed a modified alkaline-based proteomics protocol that improved the reproducibility of detecting hair proteins, potentially aiding future biomarker discovery.

This review discusses the applications of confocal laser scanning microscopy in visualizing fluorescent compounds within the skin, noting its potential for tracking drug carriers and enhancing penetration studies, but reports no new results.

This review discusses how emerging technologies in dermatology are enhancing the ability to diagnose and treat hair and nail disorders more accurately and effectively, highlighting advancements in both diagnostic techniques and therapeutic methods such as AI-driven technologies that personalize patient care and improve outcomes.

This study found that a new 3D image analysis method from SEM images enables quick and accurate measurement of cuticle scale heights in hair fibers.

This study reports that hair from women with breast cancer showed a unique X-ray diffraction feature, potentially offering a non-invasive method for detecting the disease.

This study introduced a validated LC-MS/MS-based method for profiling long-term steroid concentrations in human scalp hair, offering potential applications in endocrinology research.

This study introduced a new method for extracting red mordant dyes from wool fibers that preserved the fibers for further analysis and allowed for spectrophotometric examination of the dyes' absorption curves.

This study reviewed the current analytical techniques for estimating finasteride, a drug used for treating benign prostatic hyperplasia, acute urine retention, and male pattern hair loss.

This study developed a method using ultra-performance liquid chromatography and mass spectrometry to detect illegal substances in hair loss prevention cosmetics, revealing that some products contained high levels of minoxidil and finasteride, posing safety risks.

This study found that patients with frontal fibrosing alopecia showed significant alterations in protein expression in forehead corneocytes, suggesting the condition may have systemic implications beyond the scalp.

This study reported that in the California Ground Squirrel, certain elements bioaccumulate in hair, providing baseline data for environmental health assessments.

This review updates on various methods for hair and scalp examination, encompassing non-invasive, semi-invasive, and invasive techniques, and reports no new results.
