In this single-cell transcriptomic study, researchers analyzed AA scalp samples and found distinct immune and nonimmune cell activation patterns, with elevated TH1/TH2 and JAK/STAT markers potentially contributing to hair follicle immune privilege disruption and disease severity.

This study explored androgenetic alopecia in a large Saudi sample, finding that onset often occurs in youth, with strong family aggregation and minimal use of treatments like minoxidil, despite high rates of hair shedding during combing, especially among women.

This study evaluated the quality of 5% Minoxidil samples and found that only one out of three magistral formulations met acceptance criteria, highlighting the need for stricter quality control in custom pharmacy preparations to ensure their therapeutic efficacy.

This source reports that Malassezia restricta appears more abundantly in fecal samples and may be associated with intestinal diseases such as Crohn's disease and ulcerative colitis, but is also found in healthy contexts; future research could inform targeted therapies.

This study reported the presence of dermatophyte macroconidia directly in clinical samples from a 3-year-old boy with tinea capitis, marking the first time this has been documented. The infection, caused by Microsporum ferrugineum, was successfully treated with systemic itraconazole and topical ketoconazole shampoo.

This study applied a new RGB trichrome stain to human skin samples, revealing distinct structural staining in normal tissues and potential proteoglycan-rich zones in hair follicles.

This study found that all participating depressed women in the sample had vitamin D deficiency or insufficiency, suggesting a possible association between vitamin D levels and depression among women in Iraq.

This paper discusses various hair diseases and provides sample patient instruction sheets, offering a template for physicians to potentially integrate into their practice, but reports no new clinical results.

This review discusses the use of different biological samples, including hair, for drug testing and highlights the complexities and considerations involved in interpreting results; it reports no new findings.

This study determined the levels of several elements including iodine and bromine in hair samples from patients with various thyroid diseases compared to control groups without such conditions.

This study successfully isolated inner ear-specific exosomes from perilymph samples of sensorineural hearing loss patients using a novel immunomagnetic approach, enabling groundbreaking liquid biopsy diagnostics.

This study found that videodermoscopy enhances diagnostic accuracy for scalp and hair disorders beyond simple clinical inspection and reveals novel disease features that could improve clinical understanding.

In this study, researchers found that simple hair clipping in mice induced dynamic plasticity and axogenesis in skin sensory axons, linked to follicular activation and HGF signaling.

This study reported that a new extraction technique using cautery and forceps is a simple, effective treatment and diagnostic procedure for eruptive vellus hair cysts, with no recurrence after 4 months.

In this study, researchers developed a relatively simple punch assay for regenerating hair follicles using mouse or human cells, finding efficient hair formation with mouse cells but low efficiency with human cells on reconstituted human skin.

This study assessed hair whorl characteristics in domestic dogs and found that simple whorls predominate, with tufted whorls more common in specific regions like elbows and chests, influenced by factors such as coat traits and source.

This study found that spironolactone therapy may reduce hair width in prepubertal girls with simple hypertrichosis, though its long-term efficacy and safety remain uncertain.

Researchers developed a quick and sensitive way to measure finasteride in blood using a small sample size.

This study presented a new method for accurately measuring Fe³⁺ in small serum samples, achieving high recovery rates and agreement with established testing methods, while offering advantages such as cost-effectiveness, simplicity, and enhanced sensitivity.

The micropunctiform technique for hair restoration is safe, simple, and creates a natural hairline.

In this study, the researchers analyzed skin samples from Dun Mongolian horses to uncover molecular pathways linked to the "Bider" marking, identifying differential gene expression and several pigment-related signaling pathways that may play key roles in its formation.

This study found that clippers are the safest and most efficient tool for collecting hair samples from companion dogs, with no impact on cortisol concentration compared to scissors.

This study reported that the Fe@C/CB electrocatalyst effectively detected Metol in water samples with a low detection limit, high sensitivity, and good stability, suggesting it as a promising tool for environmental monitoring.

In this in vitro study, simple centrifugation with calcium gluconate activation led to a significantly higher release of PDGF-BB in PRP compared to other methods, which may inform improved clinical PRP preparation protocols.

In this study, high prevalence of thyroid disorders was observed among a random sample, with autoimmune processes being significant, and women notably comprising 95.65% of those studied.

This study found that additive discourse markers were the most frequently used type in a sampled news article from The Jakarta Post.

This study found that measuring stress biomarkers in hair could be an effective and simpler method for assessing chronic stress in rats, potentially offering a novel alternative to serum tests with biomarkers including sodium, calcium, and cortisol.

This study describes a gel-supported in vitro system for culturing skin samples that may effectively replace animal systems for toxicity testing, showing high correlation with in vivo skin toxicity measurements.

This study found that optimizing proteomic genotyping conditions from single human hair samples significantly improves the detection of genetically variant peptides, enhancing human identification with high precision across different biogeographic backgrounds.

This study found that hair shaft keratin proteins can be reliably identified from samples as small as 0.12 cm, suggesting their potential forensic utility with typical casework sample sizes.
