This case report describes a rare autosomal dominant hair shaft disorder, monilethrix, observed in three consecutive generations of a family, with gradual improvement noted with age.

The document concludes that hair analysis is not good for assessing nutrition but can detect long-term heavy metal exposure.

This study found that concentrated clusters of noradrenergic nerve fibers form a longitudinal linear system in rat skin, particularly innervating arrector pili muscles.

In this study, Leonuri Herba alkaloids significantly reduced prostate hyperplasia indicators and improved urinary parameters in hormone-induced model rats.

This study examined vicuña skin and hair follicle structures, finding a high density of secondary hairs in fleece areas compared to belly and legs, and identified various types of cutaneous glands potentially important for chemical communication.

This case report describes a patient with lichen nitidus whose lesions improved following treatment with oral astemizole and topical steroids, although spontaneous resolution remains a possibility.

This case report describes a 2-year-old boy in critical condition who developed anagen effluvium, possibly due to hypotension and hypoxia triggering hair follicle apoptosis.

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 article provides a diagnostic guide for clinicians to differentiate between various hair shaft disorders by using a structured question-by-question approach but does not report new clinical findings.

This article reviews hair growth and loss in children and offers diagnostic approaches, reporting no new results.

This case report describes a 6-year-old girl diagnosed with the rare concurrence of monilethrix and trichorrhexis nodosa, characterized by sparse, brittle hair, who showed minimal clinical improvement with low-dose oral and topical minoxidil treatment.

This study highlights the importance of identifying the various causes of hair loss in children to enable accurate diagnosis and management, emphasizing that proper treatment, including psychosocial support, can prevent a decline in their quality of life.

Diagnosing and treating CCCA requires understanding multiple causes and using various diagnostic tools.

This article discusses various forms of alopecia, emphasizing the need for light microscopy to investigate hair shaft disorders, and does not report new clinical findings.

This review discusses loose anagen hair syndrome in children, characterized by non-scarring alopecia and increased hair shedding, and reports no new results; topical minoxidil may be used as a treatment.

This case report describes an eight-year-old Kashmiri boy diagnosed with monilethrix, a rare genetic hair disorder, characterized by a beaded appearance and fragility of the hair shaft.

This study found that chemical and photochemical oxidative processes modify the main classes of proteins in hair, confirmed through microspectrophotometric, fluorescence microscopy, and electrophoretic methods.

This article reviews the clinical and diagnostic features of hair shaft disorders, emphasizing the role of structured patient assessments and the avoidance of hair trauma, but reports no new results.

This article reviews the steps and methods involved in preparing skin tissues for three-dimensional volumetric imaging, highlighting its potential to provide detailed insights into skin structure not possible with traditional 2D histology, but reports no new findings.

Dermoscopy greatly improves melanoma diagnosis and reduces unneeded surgeries.

This review presents an objective analysis of female androgenetic alopecia, discussing clinical and dermoscopic examination approaches but reports no new clinical findings.

This study used ultrahigh-resolution optical coherence tomography to observe hair shaft structures, finding melanin granules absent only in white hair, which may explain color differences between black and white hair.

This study found that in naturally curved human scalp hairs, distinct arrangements of cell types on either side of the hair fiber contribute to its curvature.

This study investigated the physicochemical properties of polystyrene-b-poly(acrylic acid) nanovesicles coated with modified chitosans, finding that they can effectively control surface charge and potentially serve as drug delivery carriers with a 50.7% encapsulation efficiency for minoxidil.

In this study, UV-light at 254 nm and Polyquaternium-7 treatment were found to affect the mechanical properties and surface structure of hair.

This study analyzed how oxidative hair dye leaches from pigmented and nonpigmented hair during wash cycles, finding that melanin influences the dye deposition and leaching processes.

This study investigated the effect of peracetic acid treatment on hair fiber structure and found that disulfide bond oxidation altered thermal properties while preserving the α-crystal structure, suggesting different stabilizing interactions in hair fibers.

A deep learning model was developed to help diagnose trichothiodystrophy by analyzing hair patterns.

This study found that oxidative treatment with peracetic acid dissociates some disulfide bonds in human hair fibers while maintaining the crystalline structure, suggesting different mechanisms stabilize different regions of intermediate filaments.

This study demonstrated a method for delivering a photosensitizer, Ammi majus fructuum furocumarines, into hair follicles using calcium carbonate particles, followed by UVA irradiation, which led to significant pigment accumulation, indicating potential improvements for photochemical therapy.
