This study found that low-frequency sonophoresis significantly decreased the skin penetration of sodium fluorescein-loaded PEGylated liposomes with D-limonene and affected percutaneous absorption by partially plugging hair follicle orifices.

In this observational retrospective study, UVF-dermoscopy was found to be more effective than polarized dermoscopy in identifying follicular features and distinguishing between scarring and nonscarring alopecias, particularly in individuals with lighter skin tones.

In this study, researchers used NIR-II fluorescence imaging to track the survival and migration of EPI-NCSCs in rat models, finding that these stem cells aided in repairing facial nerve defects when applied via acellular nerve allografts.

This study demonstrated that dyeing can enhance the absorption coefficient of hair follicle tissues for selective photodestruction within human skin and hair follicles.

This study reviewed the principles and classifications of hair dyes, identifying significant differences between oxidative, temporary non-oxidative, and semi-permanent non-oxidative dyes in terms of duration, application methods, and potential risks, which could help improve safety and convenience in hair dye use.

This study suggests that using UVFD to examine non-pigmented facial lesions can potentially enhance diagnostic accuracy and reduce unnecessary biopsies.

This study found that mixtures used in permanent hair dyes had irritant effects on reconstructed human epidermis, while individual ingredients alone did not.

This study found that targeting the hair follicle can be increased by using lipophilic drugs combined with surfactant solutions and propylene glycol.

This study describes a new method for extracting red mordant dyes from wool fibers using ethylene diamine tetraacetic acid and N,N-dimethyl formamide, preserving the fibers for further examination.

In this mouse study, researchers found that hydrogen peroxide and monoethanolamine in hair dyes may be key contributors to dermatitis and hair loss due to oxidative stress.

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 mesenchymal stem cells, especially when injected intradermally, significantly accelerated wound healing in rats compared to chitosan treatment.

This study found that the RapidHIT™ ID system can successfully obtain DNA profiles from single hair roots, particularly those with high nuclei counts.

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 reports that the completeness of DNA degradation in hair during cornification varies among individuals and affects the success rates of forensic hair DNA analysis.

The new system can grow hair in the lab and test hair growth treatments.

This study utilized advanced imaging techniques to quantify hair damage and dye uptake dynamics, revealing that compound penetration in hair is influenced by molecule size and lipophilicity.

This chapter reviews the anatomy and structure of hair, discusses hair damage and analyses, and explores methods for processing hair changes, but presents no new research findings.

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 found that fetal calf serum can protect Merkel cells from death and alter their morphology in culture, while serum-free conditions led to high cell mortality.

This study found that photodynamic therapy using 5-aminolevulinic acid or methyl aminolevulinate is a safe and effective treatment for acne vulgaris, particularly with 30 to 60 minutes of contact time and three treatments for significant long-term improvement.

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 found that melanin granules in black human hair are key dyeing regions for oxidative hair coloring, as confirmed by nanoscale mass spectrometry analysis detecting deuterium ions.

This study reports the synthesis of a hectorite/phenanthroline nanomaterial which acts as a potential fluorescent sensor for detecting Zn ions in water, offering a solution to the low solubility issue of traditional metal ion-detecting molecules.

Human hair structure varies by ethnicity, and certain treatments can improve hair condition and appearance.

Twisting hair weakens it, but strength can be recovered at low twist levels.

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.

A new method helps understand hair shine and various products improve hair care.

In this study, polydopamine emerged as a safe and effective alternative to traditional hair dyes like PPD for dyeing gray hair permanently, showing resistance to detergents and causing less toxicity and hair loss in mice.

Cromolyn sodium's effectiveness for treating asthma in children under 2 is unclear, possibly more beneficial for older children, and further research is needed.
