This study found that the Massachusetts General Hospital Hairpulling Scale has acceptable internal consistency and divergent validity for assessing Trichotillomania severity, but demonstrated inadequate test-retest reliability and mixed convergent validity.

This study found that local refinement of hair follicles into higher order patterns can occur without the core planar cell polarity system, but global alignment with body axes requires its function throughout development and regeneration.

This study reported the development of a workflow that combines SIMS and X-ray elemental mapping techniques for multimodal imaging at the single cell level, successfully applied to visualize elements, metals, and lipids in porcine skin without loss or delocalization.

This study found that finasteride use is not significantly associated with an increased risk of depression or suicide, based on Mendelian randomization analysis and COX regression analysis in a large UK Biobank cohort.

Photobiomodulation did not significantly improve hair density in dogs with alopecia X.

This study validated a Spanish version of the Hair Specific Skindex 29 scale for assessing quality of life in women with female androgenetic alopecia, showing similar psychometric properties to the original.

This study found that the molecular structure of hair is more sensitive to synchrotron X-ray radiation than its supramolecular architecture, indicating potential concerns for biological analyses using such radiation.

This study validated the Black Identity, Hair Product Use, and Breast Cancer Scale (BHBS) as a tool to measure social and cultural factors related to hair product use and perceived breast cancer risk in Black women.

This study developed an efficient method for converting polymeric procyanidins into high-purity oligomeric procyanidins using a semisynthetic approach combined with separation techniques.

Tailoring COVID-19 measures to risk levels in the military improves health and readiness.

This study found no significant difference in hair cortisol concentrations between sows confined in farrowing crates and those in loose-housing systems, suggesting confinement may not affect chronic stress levels.

This study reported that in mycosis fungoides and Sezary syndrome, there is male predominance and younger age of presentation in early-stage disease, with significant data collection efforts supporting biomarker identification.

This study demonstrates a varied distribution of keratins in the epidermis of the Malayan pangolin, suggesting evolutionary adaptations related to their distinctive scales.

This study found that two eco-friendly analytical methods for quantifying Finasteride and Tadalafil in a new dosage form were effective, green, and suitable for quality control.

This article describes the development and validation of a standardized instrument for measuring skin involvement in cutaneous lupus erythematosus, aiming to aid future clinical research and trials.

Human hair's ability to get wet is complex and can change with treatments, damage, and environment.

This study reports four infants with necrotic caput succedaneum leading to alopecia and persistent scalp lesions, which partially improved with topical corticosteroids, indicating erosive pustular dermatosis of the scalp.

This study describes a newly recognized skin reaction associated with dasatinib, nilotinib, and ponatinib, marked by a lichenoid exanthem with severe pruritus that may necessitate discontinuation of therapy.

This study found that aging in Korean individuals is associated with changes in hair diameter and surface structure, as observed through atomic force microscopy.

This study found that both everyday physical and environmental stresses, as well as chemical treatments, contributed to hair damage, with cuticle layers being more noticeably affected.

This study found that while the CLASI is generally useful for assessing disease activity and damage in cutaneous lupus erythematosus, it may not accurately reflect all subtypes, indicating a need for revision.

This research examined the ultrastructure of deer hair fibers and found significant variations in diameter, cuticle thickness, and intermediate filament arrangements among different fiber types.

Hair from people with seborrheic dermatitis is thicker scaled, more damaged, and thinner than healthy hair, and atomic force microscopy can help monitor the condition.

Some oils can penetrate hair and reduce the stickiness between fibers, but mineral oil cannot.

This study found that the down-hair fibers of native goats in Turkey have similar characteristics to cashmere fibers, indicating potential for high-quality textile products as a substitute.

This study found that L-cystine-modified rabbit hair fibers had improved dye adsorption and spinnability, due to changes in secondary structure and surface characteristics.

This study observed that different hair types on Tianzhu white yaks have similar ultrastructures, but coarse hair fibers show distinct structural differences across body parts.

This study concluded that Polyquaternium-10 conditioner softens the surface of the scale face on hair fibers.
