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

Human hair growth involves active, resting, and intermediate phases, and examining plucked hairs can teach students about hair biology and diseases.

In this study, researchers found that hair fibers exposed to bleaching and UV irradiation displayed significantly more damage, including increased adhesion and surface heterogeneity, compared to untreated hair, highlighting a synergistic degradation pathway affecting the hair cuticle's integrity.

This case report describes a rare presentation of recurrent plaque psoriasis on the penile shaft, which was controlled with systemic therapy after topical treatments failed.

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

This study found that freeze-dried finasteride nanoparticles significantly improved the dissolution rate and pharmacokinetic parameters compared to pure drug formulations, suggesting enhanced stability and solubility for poorly water-soluble drugs.

This study demonstrates that confocal laser scanning microscopy can effectively visualize the rapid diffusion and penetration pathway of a dye into the hair follicle in fresh human scalp skin.

This study presents a DNA-analytical method that can reliably identify and differentiate cashmere, fine wool, yak, and camel hair fibers in both untreated and processed samples.

This review explores the structure and development of the hair cuticle, highlighting difficulties in studying some aspects and proposing new experimental approaches, but reports no new clinical results.

This study observed that lipids in human hair accumulate in specific areas and do not significantly impact water permeability, highlighting the utility of AFMIR for studying complex biomaterials.

This chapter reviews hair anatomy, hair shaft structure, and various cosmetic treatments that can alter or damage hair, but it presents no new research findings.

This study discusses the potential of advanced imaging technologies in dermatology to improve diagnostic accuracy and reduce the need for invasive procedures like biopsies, while noting significant barriers in adoption and accessibility in India due to costs and infrastructure constraints.

This study discusses using SEM/EDX for elemental analysis of hair samples in forensic science but notes challenges in detecting certain trace elements from raw hair.

This study found that high-charge-density cassia HPTC improves deposition efficiency and conditioning benefits in shampoos compared to quaternized guar, suggesting its potential as an alternative or adjunct conditioning agent.

This study observed that sonidegib led to a meaningful clinical response in a real-world Chinese cohort with locally advanced basal cell carcinoma, although pathological biopsy remains essential to confirm tumor clearance due to false positives in noninvasive assessments.

This report describes the diagnosis and treatment of traumatic anserine folliculosis in children, highlighting its distinct skin features and suggesting tretinoin cream as an effective remedy.

This study found that both intradermal injection and derma roller techniques for QR678Neo® hair regrowth therapy improved androgenetic alopecia symptoms, with intradermal injections showing non-significantly better video-microscopic outcomes but more pain and erythema associated with derma rollers.

This paper reviews hair loss associated with various endocrine disorders and describes both traditional and emerging non-invasive diagnostic methods without presenting any new clinical results.

This paper discusses the use of dermatoscopy as a fast, noninvasive technique for diagnosing hair shaft disorders and reports no new results; the authors highlight its advantages over traditional microscopy methods.

This article illustrates various hair shaft defects and suggests that dermatologists can diagnose most of them using light microscopy and polarization without needing advanced imaging techniques.

This article outlines methods to study the skin and its molecular traits, focusing on interpretation and techniques applicable to mouse models, including diverse assays and approaches like electron microscopy and large-scale lipid analyses.

This study found that human hair follicles emit electromagnetic fields due to metabolic activity linked to S100 proteins, visualized using a novel microscopic technique with nano-sized iron particles.

This manuscript presents a hypothesis linking the intrinsic pulsating bioelectromagnetism of human hair follicles to the etiology of migraine headaches, supported by studies of inherent biomagnetism using optical microscopy techniques.

This article discusses the follicular-unit grafting technique for hair transplantation and reports no clinical results; the authors highlight its potential for achieving natural-appearing outcomes but note the procedure's complexity.

This study found that optical coherence tomography provides highly reproducible and less variable measurements of hair shaft thickness compared to standard light microscopy, offering a promising noninvasive tool for clinical practice.

This review provides an overview of how advancing imaging technologies, such as tissue clearing and intravital microscopy, are enhancing our understanding of tumor architecture and interactions between cancer cells and the tumor microenvironment, aiding both fundamental cancer research and the development of therapies.

This review highlights how intravital microscopy has advanced understanding of tissue homeostasis and cancer progression, focusing on how tumor cells exploit physiological processes for growth; it reports no new experimental findings.

This study explored the use of multiphoton microscopy to monitor changes in tumors and surrounding tissues in breast cancer patients undergoing neoadjuvant chemotherapy, finding it may effectively detect treatment response at cellular levels without using exogenous contrast agents.

This study discusses eyebrow reconstruction techniques, highlighting the correction of unsatisfactory transplants using donor hair without laser or tattoos, focusing on factors like hair follicle density and eyebrow shape.

This study observed that processing techniques such as degreasing, bating, and tanning influence mink skin by altering the distribution of fat glands and collagen fibers, potentially impacting hair follicle structure and mink product quality.
