This review discusses the advancements and applications of multiphoton microscopy in dermatology, including its role in imaging skin disease and drug transport, and reports no new clinical results.

This study observed that ultrastructural changes like lamellar bodies and electron-dense granules in the stratum corneum may aid in the early diagnosis of Netherton syndrome.

This article reviews various microscopy techniques and their applications in dermatology but reports no new experimental results.

This article examines microscopic structural differences and pigment distribution in various rabbit hair colors and reports no clinical results.

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

This article outlines a protocol for scanning electron microscopy of murine skin and primary keratinocyte monolayers, providing a guide for sample preparation and examination.

This review outlines the practical use of reflectance confocal microscopy in dermatology, detailing its applications and considerations for diagnosing various skin conditions, but reports no new findings.

In this study, researchers used SEM/SDD-EDS to identify waterborne minerals like calcium and aluminum in the scalp hair cuticle of individuals using treated or untreated water for hair washing, finding that prior application of coconut oil or conditioners can prevent calcium uptake.

This study found that using a microscope can effectively distinguish between human and animal hair based on microscopic characteristics, making it a critical tool in forensic investigations.

This review highlights that two-photon excitation microscopy is a valuable tool for visualizing live skin structures and immune responses at high resolution, though its clinical use is hindered by safety and cost issues.

This study used advanced optical imaging techniques to investigate nanoparticle and dye penetration in human skin, finding that nanoparticles mainly resided in the stratum corneum and accumulated in skin folds and hair follicles, while highlighting that sunscreen-based nanoparticles appear unlikely to pose safety concerns.

This study used light sheet fluorescence microscopy to successfully image and analyze calcium oscillations in the root hairs of Arabidopsis thaliana, finding that these oscillations correlate with the root hair growth rate and that auxin affects these properties.

This study investigated the tensile response and morphological changes of different ethnic hair types using AFM, showing variations between virgin, chemically damaged, and conditioner-treated Caucasian hair under different conditions.

This study identified distinct microscopic characteristics of acne scars, including inflammatory infiltrates and insufficient collagen deposition, suggesting that treatment should consider these histopathological findings and employ combination therapy.

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 in vivo confocal scanning laser microscopy accurately quantifies neogenic hair follicles in mice, producing results similar to histology while avoiding fixation artifacts.

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.

In this study, R-CSLM showed promise in evaluating hair shaft diseases by providing high-quality images of hair structures, although further development is necessary for follicle and perifollicular area analysis.

The hair follicle structure is more complex than thought, with new findings on protein formation.

Hair malformations may occur due to timing issues in hair development.

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

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

Touch domes in human skin are complex sensory structures not directly linked to hair.

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.

This study observed that daily selenium sulfide shampoos successfully removed fungal spores hidden beneath the hair cuticle in patients infected with ectothrix Microsporum canis.

This review provides guidance on using two-photon microscopy for real-time and long-term visualization of stem cell activity in live mice skin, focusing on its application in researching skin and stem cell biology.

This study found that a new 3D image analysis method from SEM images enables quick and accurate measurement of cuticle scale heights in hair fibers.

This case report describes a 3-year-old male with X-linked ichthyosis and associated neurologic abnormalities, identifying an unusual cortical development malformation and suggesting that abnormal hair banding may assist diagnosis.

The study found that a polymer treatment changes the charge on hair surfaces, making bleached hair smoother and less porous.
