This review discusses micro needling as a therapeutic option for various dermatological conditions, such as scars and pigmentation, and reports no new clinical results; the authors note potential side effects and contraindications.

This study observed that a course of micro needle mesotherapy improved hair and scalp condition in males with alopecia.

This study reported that micro-needling with Low-Level LED Therapy and Growth Factors may improve hair density in mild-to-moderate hair loss and telogen effluvium related to COVID-19, based on preliminary observations.

This study found that micro-computed tomography (micro-CT) was highly effective for analyzing the cross-sectional geometry of hair fibres, including the medulla in highly curled hair, but less effective than scanning electron microscopy for surface details.

This study found that dutasteride mesotherapy increased the diameter of existing hair in five Mexican men with androgenetic alopecia, without reported side effects.

In this preliminary study, topical treatment with oxygen-carrying micro/nanobubbles hastened the healing of full-thickness burn wounds in a rodent model, compared to saline-treated controls.

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.

The researchers developed semi-dissolving microneedle patches using TEMPO-oxidized bacterial cellulose nanofibers, which allow effective transdermal drug delivery by forming micro-channels for large drug quantities, overcoming traditional microneedles' low drug loading.

This study found that applying BMP2 stimulated limited regeneration of the amputated P2 bone in mice, but only when applied during a specific "regeneration window" after injury.

This study developed a method for extracting proteins from micro-sized human head hairs, facilitating proteomic analysis even with limited hair sample availability.

This paper outlines the research plan and current progress of a study analyzing mineral metabolism changes in astronauts by examining hair shafts after long-term space flight, with no new results yet.

This review explores the applications of phytonutrient-based biosensors in micro-electrochemical systems and reports no new experimental findings, emphasizing the potential and challenges of this innovative approach.

This review highlights how forensic drug analysis in hair using modern instrumental techniques offers advantages such as easy sample collection and chronological tracking of drug use, emphasizing its value for law enforcement and other applications.

This article reviews recent advancements in forensic hair testing, emphasizing its growing use for detecting past substance exposure, identifying emerging trends like micro-segmentation and hair scanning, and proposing standardized procedures to improve reliability and application in forensic toxicology.

In this study, researchers used atomic force microscopy to capture and analyze morphological changes in the surface of healthy hair, identifying features such as pitting and rod-shaped macro-fibrillar elements, which could inform future research on hair conditions and care.

This study reported that using autologous micro-grafts according to the Rigenera® protocol may improve hair restoration and increase hair follicle numbers in patients with androgenetic alopecia after 6 to 9 months.

This literature review conducted a comprehensive analysis of existing studies on micro-needling mesotherapy in dermatology and aims to offer a practical guide for its clinical application, though it provides no new experimental findings.

This review discusses micro-segmental hair analysis for forensic toxicology, emphasizing its potential to provide detailed drug distribution profiles and its application in investigations, while noting the method's limitations and future perspectives.

This study found that micro-needling with cosmeceuticals or platelet-rich plasma significantly improved wrinkles, skin laxity, scar softening, and hair growth over 12 months, with minimal side effects, and that the best results occur with pigment and platelet massaging between 5 to 30 minutes post-treatment.

This study found that combining micro-needling, low-level laser therapy, and autologous non-activated platelet-rich plasma increased hair density in patients with androgenic alopecia over the treatment period.

This study found that micro-current electrical stimulation may promote hair growth in human hair follicle-derived papilla cells and a mice model by enhancing cell proliferation, migration, and activating key growth pathways.

This study found that "micro skin tissue columns" improved wound healing by enhancing re-epithelialization, collagen deposition, dermal remodeling, and reducing inflammation without causing long-term donor site morbidity.

This study concluded that controlled micro-injury induces hair regeneration and vitiligo repigmentation in mice, potentially through the Wnt/β-catenin pathway.

This study introduced mechanical setups to analyze the mechanical properties of root hairs in Arabidopsis thaliana, finding that axial stiffness primarily relates to tip compression and turgor pressure, confirmed by independent methods adapted from work on animal cells.

In this study, researchers developed innovative mechanical methods to measure the mechanical properties of Arabidopsis thaliana root hairs, concluding that axial stiffness is mainly due to tip compression and influenced by turgor pressure.

This study highlights that current research efforts to deliver anti-acne drugs to hair follicles have primarily targeted healthy follicles, overlooking the distinct characteristics of pathologically clogged follicles in acne vulgaris.

This source provides an overview of diagnostic and treatment innovations for gastrointestinal disorders, such as wireless capsule technology for motility assessment and new methods for treating constipation and nausea, highlighting both current and emerging techniques.

This study found that hair from the vertex posterior is a reliable sampling region for detecting zolpidem intake, showing consistent drug concentration and peak position compared to other scalp regions.

This review suggests that microneedling shows promise for improving hair quality, thickness, and density in treating androgenetic alopecia, but standardized treatment protocols are currently lacking.

This study proposes the miR-22-5p-LEF1 axis as a novel pathway that may regulate hair follicle stem cell proliferation.
