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 review highlights recent advances in laser treatments for skin disorders, including the optimization of vascular lesion treatment and improved safety for hair removal, but reports no new results.

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 review outlines key considerations for designing fluorescence microscopy experiments in cell biology, discussing the importance of hardware availability, suitability of biological models, and imaging agents to achieve high-resolution and informative images.

This study reports that structural abnormalities in the inner root sheath of hair follicles may cause the hair shaft to be loosely attached in patients with loose anagen hair syndrome.

This study found that involucrin likely plays a key role in forming the cornified material of the medulla and inner root sheath of human hair, contributing to its mechanical strength.

This study concluded that epidermal growth factor may induce a 'catagen-like' phase in human hair follicles by disrupting normal cellular proliferation and migration patterns.

This article reviews various hair abnormalities observable through trichoscopy in conditions like monilethrix, trichorrhexis nodosa, and ectodermal dysplasias, with no new clinical findings reported.

In this study, the researchers reported the detailed anatomical structure of horse skin, including the composition and organization of the epidermis, dermis, and associated glands and follicles.

This report identified longitudinal grooves in the hair shafts of four children, diagnosing them with uncombable-hair syndrome.

This study visualized mitochondrial metabolism in cultured bovine hair follicles and plucked human hairs, finding that ROS and mitochondrial polarization correlate in specific hair follicle regions, particularly near keratin deposition sites.

Hair analysis can offer clues about a person, but individual differences limit making precise identifications.

Understanding hair follicle structure is key for treating hair disorders and could help develop new treatments.

This study found that telocytes in human scalp tissue were located around hair follicles and glands and may be involved in skin regeneration and homeostasis.

This study analyzed animal hairs from 18th-century burial sites in Mazamet, France, reporting distinct hair morphologies consistent with the use of common local animal furs such as goat, badger, cow, or horse, reflecting the modest socioeconomic status of the individuals interred.

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 review discusses the development and application of multiphoton microscopy in dermatology, highlighting its advantages and potential future research directions without reporting new clinical results.

This study found that IPL hair reduction led to significant decreases in hair count and thickness by promoting hair follicle miniaturization, increased telogen phase, and reduced cell proliferation.

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.

This study reported that using photomnemonics facilitated accurate histopathologic interpretation of horizontal scalp sections in distinguishing between nonscarring and scarring alopecias by dermatopathologists and residents in a validation test.

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 concluded that horizontal sections of scalp biopsy specimens provide more diagnostic information for male pattern androgenetic alopecia than vertical sections and can predict hair regrowth potential following topical minoxidil therapy.

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 proposes an innovative treatment for stretch marks by combining skinbooster and microneedling techniques, which induce tissue remodeling and collagen synthesis, and suggests using confocal microscopy as a valuable tool for monitoring skin changes in aesthetic dermatology.

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 review discusses the applications and advantages of LED-based photobiomodulation therapy for dermatological and cosmetic purposes but highlights existing challenges and health concerns while exploring future perspectives.

This review summarizes the characteristics of the peri-malignant melanoma stroma, indicating its potential role in early dermal metastatic migration and increased metastasis risk.

This study found that intense pulsed light treatment primarily targets pigmented structures in hair follicles and may damage dermal papilla cells at high energy levels, but stem cells are mostly spared.

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 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.
