This study characterized hair from a patient with a ribosomopathy and identified distinct differences, including reduced hair thickness and lipid content, compared to family members.

This study demonstrated that using finasteride impurity as a non-isotopically labeled internal standard in paper spray ionization–mass spectrometry can effectively and efficiently measure finasteride tablet dissolution, achieving results comparable to high-performance liquid chromatography.

This study reports that compound heterozygous loss-of-function mutations in the HEPHL1 gene in a child were associated with abnormal hair and cognitive issues, linking altered ferroxidase activity to hair disorders.

This study explored non-invasive methods for monitoring low molecular weight biomarkers on the skin's surface, concluding that certain amino acid ratios, such as Phe/Trp, could serve as potential indicators of skin inflammation and cancer.

In this study, researchers improved the synthesis process for finasteride, reducing impurity levels and making it suitable for industrial production.

The two finasteride formulations are bioequivalent.

This study suggests that elevated copper levels in domestic tapwater, exacerbated by its aggressive properties, likely contribute to green hair by damaging the cuticle and increasing copper uptake.

This study found that using near-infrared optics, specifically in the second NIR window, allows for effective noninvasive evaluation of intra-hair damage caused by cosmetic treatments, demonstrating distinct damage types and changes in hair condition due to chemical or thermal processes.

This study presents two cases correlating the clinical appearance of adult-onset foveomacular vitelliform dystrophy with optical coherence tomography findings, describing the location of the yellow vitelliform material.

This study found that PX-12 inhibited the NLRP3 inflammasome and reduced psoriasis-like symptoms in a mouse model, suggesting its potential as a treatment for psoriasis.

This study successfully developed a method to measure four flavonoids from Platycladus orientalis leaves in rat plasma, which was used in a pharmacokinetic study on healthy rats.

This study found that a modest increase in dietary zinc over six months resulted in a detectable increase in sulfur and zinc counts in individual hairs, suggesting a non-invasive method to monitor zinc intake effects.

In this study, researchers observed bright colored patches in the hair of diabetic patients under cross polarized light, suggesting a potential non-invasive diagnostic method for diabetes.

This case report describes novel trichoscopic features of anagen effluvium caused by azathioprine in a patient with normal TPMT levels, emphasizing the importance of regular monitoring for adverse effects.

This study concluded that two formulations of finasteride were bioequivalent based on Cmax, AUC, and Tmax data from healthy volunteers.

A new, quick method accurately detects minoxidil in drugs and cosmetics.

This study developed a new method using ultrahigh-power sonication and mass spectrometry to improve protein extraction from hair shafts, identifying 239 differentially expressed proteins related to fetal growth restriction, which were validated as potential noninvasive biomarkers for perinatal diagnostics.

New method effectively analyzes finasteride and its stability.

This case report describes a 7-year-old boy with pityriasis versicolor presenting as scalp hypopigmentation, a rare distribution for this fungal infection. Diagnosis was confirmed via Wood's lamp examination and microscopy, and the condition resolved after treatment with topical terbinafine hydrochloride cream.

This study found that a new analytical approach revealed an increased brain pregnenolone level following finasteride treatment in a mouse model, suggesting potential for improved understanding of neurosteroid roles in brain excitability.

This report describes four cases of monilethrix in children and concludes that periodic inhibition of keratin synthesis, not a metabolic defect, may explain the hair abnormality.

This study found that human hair follicles demonstrated a dose-dependent response to light in an ex vivo photoepilation model, which could predict the clinical efficacy and permanency of light-based hair removal devices.

This study reports that A132, a hair dye ingredient, induces phototoxicity and photogenotoxicity via mitochondrial apoptosis when exposed to sunlight, suggesting potential risks of oxidative stress and hair damage.

This case report describes a 6-year-old girl diagnosed with monilethrix despite no familial history and treated with a topical minoxidil trial.

This case report describes three Iranian men with gradual reddish-brown pigmentation on their cheeks and preauricular areas since childhood, unresponsive to sunblocks and topical steroids.

This study observed light flashes and repulsion effects in a single-slide preparation of human hair with a special solution, suggesting potential electromagnetic field emissions from the hair.

This study reports that two novel chromatographic methods demonstrated high sensitivity and selectivity for determining aminexil, niacinamide, and pyridoxine HCl in a laboratory-prepared mixture and hair tonic preparation.

In this study, researchers identified a novel biomarker of oxalate metabolism, which plays a crucial role in conditions like hyperoxaluria and kidney stones, marking the first time this detection has been reported.

In this research, SEU-302, a newly developed covalent organic framework, exhibited significant antibacterial and wound-healing properties in vitro and in vivo, effectively eliminating Staphylococcus aureus and reducing inflammation under light activation, thereby showcasing its potential for therapeutic photodynamic applications.
