Alopecia linked to higher anxiety and personality disorders.

This protocol describes using two-photon laser-scanning microscopy to study hair regeneration in live mice, offering detailed imaging capabilities for observing hair follicle stem cell behavior and manipulating cellular populations.

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 study developed a quantitative method using SDS-PAGE and MALDI-TOF mass spectroscopy to accurately determine animal species from hair fibers, validated against standard samples and optical microscopy.

This paper introduces a new microscopy technique to measure biomagnetic fields of human hair follicles using Prussian Blue Stain mixed with iron particles, but it reports no new clinical results.

This chapter highlights various commercial and open-source light sheet microscopy systems, detailing their rapid evolution and integration of multimodal technologies, with a focus on the ZEISS Lightsheet Z.1 system's advanced design for direct imaging and specialized sample mounting.

This study identified the best cream-mask base composition for treating androgenetic alopecia using Saw palmetto and Sophora Japonica, which includes specific emulsifiers and polymers for optimal consumer and pharmaco-technological properties.

This study found that the optimal method to introduce Saw Palmetto extract into emulsion bases for androgenic alopecia treatment involves mixing it with 48% ethanol at the end of the formulation process.

This study conducted a comprehensive analysis of methods for assessing surface roughness, highlighting that contact methods using profilometers provide accurate results for machine parts, while non-contact optical and laser methods offer high precision and efficiency without damaging surfaces.

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 study found that quercetin-loaded solid lipid nanoparticles demonstrated positive protective effects on human hair against UV-B light, as they controlled microscopic surface roughness, reduced chemical changes, and minimized protein loss in vitro compared to other treatments.

This study experimentally validated Lockhart's viscoplastic framework for tip growth in Arabidopsis root hairs by demonstrating alignment with observed growth rates and estimating yield turgor pressure and cell wall viscosity, offering a methodology adaptable to other species and conditions.

This study found that exposure to Prussian Blue caused significant detachment of cuticle segments from the hair shaft in both new and aged human hairs.

This study demonstrated that urea significantly accelerates the diffusion of poly(ethylene imine) into bleached human hair by increasing the diffusion coefficient twofold.

This study found that when human hair follicles are immersed in hydrogen peroxide, the resulting oxygen bubbles indicate catalase activity, and their absence may suggest tissue death.

In this study, researchers observed that basil seed exudate provides a protective barrier against lead toxicity in the initial stages of seed germination, even though root hairs eventually suffer from necrosis, demonstrating acute but non-lethal phytotoxicity of lead in agricultural contexts.

This study documented that human hair shafts exhibit bipolar electrical properties, potentially influencing blood coagulation by inducing fibrin formation through a positive side of the shaft.

This study reports the demonstration of electromagnetic energy transfer from human blood tissue to a human hair follicle through a 1 mm glass barrier, using in vitro experiments.

This study concluded that noninvasive imaging techniques offer potential benefits in managing scalp conditions by potentially reducing the need for biopsies and minimizing patient morbidity, each technique having unique advantages and limitations for specific conditions.

This study characterized hair from a patient with a ribosomopathy and identified distinct differences, including reduced hair thickness and lipid content, compared to family members.

This study developed O/W hair mask emulsions with collagen hydrolysate, keratin, and natural oils, reporting that they are stable, physiologically acceptable for skin, creamy, non-greasy, and hydrophilic, with properties suitable for cosmetic applications in hair care.

This study presents additional data suggesting that the absence of nerve endings in certain segments of human hair follicles influences the asymmetrical distribution of electrical charges, as indicated by no precipitation of Potassium Ferricyanide crystals.

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.

This study found that econazole nitrate delivered via MPEG-dihexPLA micelles significantly increased skin deposition compared to Pevaryl® cream, potentially enhancing drug bioavailability and clinical efficacy.

This study describes molecular mechanisms explaining how sex and stress steroids rapidly modulate dendritic spine formation in hippocampal neurons, suggesting recovery-like effects under steroid-depleted conditions compared to intact conditions.

This study found that adding hair fibers to friction materials increased their friction coefficient stability and impact strength while decreasing wear rates, with 1% hair fiber content notably improving performance.

This study found that proretinal nanoparticles, applied topically, are safe and effective for penetration into hair follicles, enhancing retinoid biological activity in the skin while reducing irritation compared to conventional retinal formulations.
