In this study, incorporating a novel amino acid compound into a hair-straightening formulation improved humidity-resistant straightening and enhanced the surface and mechanical properties of hair fibers, including increased bending stiffness, reduced friction, and better shape retention under high temperature and humidity conditions.

This review explores the use of topical and transdermal delivery for drugs and cosmetics, highlighting the benefits of avoiding side effects and rapid metabolism, with a focus on nanoparticulate formulations and techniques for studying skin penetration.

This review discusses the potential of adipose-derived stem cell extracellular vesicles (ADSC-EVs) in skin regeneration, highlighting mechanisms like inflammation and angiogenesis, but reports no new clinical results; challenges and future prospects are also considered.

This study found that novel thiol-reactive cross-linking agents, particularly APA, significantly improved the tensile strength and elasticity of human hair fibers by effectively regenerating disulfide bridges, with potential applications for advanced hair repair treatments in the cosmetic industry.

This study found that 3D microtissue models of dermal papilla cells can enhance the ability to induce hair-follicle neogenesis in vivo, offering potential for controlled cell production in follicle regeneration.

This study reviews various skin models and methodologies used to assess the follicular penetration of nanoparticle-based drugs, highlighting inconsistencies that complicate comparisons and aims to establish more uniform protocols for clearer study outcomes.

In this study, a dual recombinase-mediated genetic system showed that cavity macrophages accumulate on the surface of visceral organs during lung and liver injury but do not penetrate or contribute to tissue repair.

This study found that ZnO nanoparticles in topical skin products do not penetrate beyond the outer skin layers in humans, suggesting minimal safety concerns for subdermal absorption.

In this study, researchers found that chemical treatments like bleaching can cause severe damage to the hair cuticle, with previously modified hair showing complete deterioration compared to the partial degradation seen in virgin hair, highlighting the need for mindful cosmetic practices.

This study found that two years after treatment, the continuous-wave Sharplan 40C SilkTouch laser system led to better collagen organization compared to the pulsed Coherent 5000C UltraPulse system in patients who underwent skin resurfacing.

This study developed a niosomal delivery system loaded with tretinoin and bicalutamide, optimized for follicular targeting in acne management, showing promising accumulation in hair follicles in animal models.

In this study, researchers found that a protein-enriched cream made from Spirulina platensis improved the physical structure of natural hair, as evidenced by more intact and smoother cuticles compared to a control cream without protein, suggesting its potential for hair care applications.

This research developed a zinc-doped nanocomposite using biodegradable materials, observing effective bone targeting and regeneration capabilities in vivo, with no observed cytotoxicity in the MG63 cell line, potentially due to blocking Farnesyl Diphosphate Synthetase to inhibit osteoclastic activity and promote osteogenesis.

This article reviews the role of factor Xa inhibitors like Rivaroxaban and suggests they may eventually replace vitamin K antagonists, but their side effects require further clarification.

This study developed chemical fingerprints to differentiate Eclipta prostrata and Wedelia calendulacea, two plants often confused and adulterated in the Indian herbal market, identifying distinct chemical profiles that can prevent such adulteration.

This study introduces a novel non-invasive method called "differential stripping" to quantify the penetration of topically applied substances into hair follicles.
