This study found that examining the microscopic and ultramicroscopic structures of donkey and horse hair can help differentiate between the species based on distinct differences in hair cuticle and brain substance patterns.

This review discusses the genetic disorder, monilethrix, characterized by fragile, brittle hair and its inheritance patterns, and reports no new clinical results.

This study identified specific reflectance confocal microscopy features that help differentiate scarring from non-scarring alopecia, providing a non-invasive diagnostic tool.

This article evaluates reflectance confocal microscopy features of scalp melanoma but reports no new clinical results, suggesting further investigation is needed.

In this case report, narrowband-UVB phototherapy successfully treated a rare instance of Graham Little-Piccardi-Lassueur syndrome, a variant of lichen planopilaris, as investigated through non-invasive imaging techniques.

This study utilized polarized light microscopy to examine hair shafts in ten children with rare genetic disorders, such as Netherton syndrome and ectodermal dysplasia, providing valuable diagnostic insights into hair thickness, composition, and structural irregularities associated with these conditions.

In this study, a 3-year-old Japanese child with autosomal recessive woolly hair was found to have a distinctive irregular and rough cuticle on the hair shaft, along with a homozygous pathogenic LIPH variant, suggesting a critical role for genetic analysis in understanding rare hair conditions.

In this study, reflectance confocal microscopy was used to diagnose periorificial dermatitis, revealing specific skin changes such as hair follicle dilatation, increased vascular density, and inflammation, which help distinguish it from similar conditions.

This study found that combining optical clearing methods with light-sheet fluorescence microscopy allows detailed 3D visualization of normal and pathological human skin biopsies, revealing differences in epidermal thickness and volume.

This study found that high-speed optical coherence tomography may be a promising non-invasive tool for analyzing human hair conditions.

This study found that the TrichoScan Professional V3.0.8.76 shows high reproducibility in measuring hair count and density but may not be effective for distinguishing hair growth phases in women with androgenetic alopecia.

This study found that fluconazole was associated with telogen effluvium in both a rat model and human patients, although retinoic acid levels were not identified as a causal factor.

The researchers reported that in hairless mice, epidermal cell division orientations and epidermal thickness varied by body site, with dorsal and ear epidermis primarily dividing parallel to the basement membrane, unlike hind paw and tail epidermis.

This study found that excessive heat caused the most significant structural changes in hair from Caucasian and Afro samples, especially when combined with other treatments like bleaching and straightening.

Reflectance confocal microscopy is a useful, non-invasive tool for diagnosing some skin diseases, with potential for future improvements.

Reflectance confocal microscopy can tell apart white dots on the scalp as either sweat gland ducts or hair follicle openings.

This study suggests that RCM may be a promising non-invasive diagnostic tool for alopecia areata incognita, showing substantial agreement with histopathology while noting some discrepancies.

This study used air wedge interferometry to measure the thickness of human scalp hair from three individuals, finding average thicknesses of 66.482 µm, 59.355 µm, and 59.927 µm respectively, within the typical range for adults.

This study introduced a novel, weakly supervised method for segmenting hair in Scanning Electron Microscope images using simple image-level annotations, achieving over 30% improvement in mean Hausdorff Distance compared to Unet and SAM, while enhancing interpretability and refinement.

This study found that scanning electron microscopy revealed significant hair shaft changes in women using straighteners, but not in those using hair dye, suggesting its utility in assessing chemical treatment effects on hair.

This study found that acne lesion formation involves early hyperkeratinization and inflammation around hair follicles, creating a self-sustaining cycle that may progressively worsen acne.

This article outlines a detailed framework for taking dermatological history and examination, emphasizing the importance of considering various factors like medication and occupational history; it reports no new clinical findings.

Reflectance confocal microscopy can noninvasively diagnose onychomatricoma by showing unique features different from healthy nails or nail fungus.

In this study, flutamide at therapeutic doses caused significant histological changes in the testes and epididymis of adult albino rats, reducing androgen receptor immunoreactivity and increasing estrogen receptor immunoreactivity.

This study introduces a five-modal microscopy technique that allows label-free, in vivo observation and quantitative analysis of various wound healing processes.

This study used in vivo confocal microscopy and a ResNet34 deep learning model to classify meibomian gland images with an AUROC greater than 0.95, indicating its potential for automatic diagnosis and screening of meibomian gland dysfunction.

This study utilized advanced imaging techniques to quantify hair damage and dye uptake dynamics, revealing that compound penetration in hair is influenced by molecule size and lipophilicity.

This study concluded that combining the Shumin treatment instrument with oral doxycycline provides better clinical outcomes for rosacea than combining red light therapy with doxycycline, while both regimens improved quality-of-life scores and reduced Demodex counts.

This research found that Foxc1 transcription factor and COL17A1 are critical in regulating quiescence and hair thinning in hair follicle stem cells, with aging-related DNA damage leading to hair loss.

This review discusses how recent advances in live imaging have revealed the dynamic and adaptable nature of stem cells during various biological processes, and reports no clinical results.
