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

This paper discusses the use of Digital Volumetric Imaging with fluorescent dyes to visualize and compare the interior structures of six different virgin hair types, reporting no new clinical results.

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

This study found that enzymatic phosphorylation of hair keratin increased its capacity to adsorb cationic components like methylene blue and may have practical implications for hair care products.

This animal study found that intravenous administration of anionic squarticles, a lipid nanoemulsion, increased survival rates in rats with amitriptyline overdose by mitigating adverse effects and restoring normal blood pressure, highlighting its potential as a detoxifying antidote.

This study found that washing hair with surfactants reduces the internal density of hair due to cuticle lifting, and suggests that a cuticle-sealing strategy can inhibit this effect and maintain hair homeostasis.

In this study, shampoos containing sodium lauroyl methylaminopropionate showed superior coacervate formation and lubrication on wet hair, outperforming other amino acid surfactants and suggesting potential for creating low-irritation, high-performance hair products.

This chapter describes the functions and purposes of hair care cosmetics, including shampoos, hair growth promoters, and grooming products, without reporting new experimental findings.

This review discusses niosomes' increasing popularity in dermatology for topical drug delivery due to their ability to enhance drug penetration, provide sustained release, and carry various drugs, while reporting no new clinical findings.

This study found that a peptide treatment using Protein disulphide isomerase improved the mechanical and thermal properties of over-bleached hair by promoting deeper peptide penetration and attachment.

This review discusses the use of microbial biosurfactants as a safer alternative to chemical surfactants in cosmetics due to their antibacterial, moisturizing, and low toxicity properties, but it reports no new clinical findings.

This article reviews the composition and functionality of shampoos, emphasizing the role of surfactants in cleaning and conditioning hair, and reports no new experimental results.

This review examines ethosomal structures and their mechanisms as skin delivery systems, outlining preparation methods and applications but presents no new experimental findings.

The study found that a polymer treatment changes the charge on hair surfaces, making bleached hair smoother and less porous.

This article reviews the development and formulation of shampoos, emphasizing their dual role as cosmetic and medicinal products, but presents no new experimental findings.

In this study, researchers highlighted that while hair lipids are crucial for hair health and protection, surfactants in shampoos and conditioners can partially remove these lipids, potentially affecting hair structure, though the exact mechanisms remain poorly understood and require further investigation.

This review discusses the evolution of modern shampoos from basic cleansing agents to products with specific therapeutic uses and emphasizes the importance of dermatologists understanding shampoo mechanisms and appropriate selection for scalp and hair health.

This review examines the advances in nanostructured lipid carriers for treating hyperpigmentation but presents no new clinical results; the authors highlight their potential benefits and applications.

This review discusses various nanoparticles used to enhance skin permeation and target delivery to skin organelles, but reports no new experimental results.

This review summarizes the promising role of melatonin combined with nanosized carriers in drug delivery, suggesting enhanced effectiveness in treating various diseases compared to free melatonin.

Niosomes are a promising and effective way to deliver drugs through the skin.

This review discusses cultural hair care practices for African American scalp health and recommends combining clinical evaluation with cultural knowledge, but reports no new research findings.

This study concluded that sodium lauryl sulfate is very toxic to hair, damaging its structure, while natural conditioners help protect hair integrity and improve consistency and shine.

This article reviews potential causes and treatments for sensitive skin and reports no new clinical results; the authors emphasize neurogenic inflammation and cosmetic choices as key factors in managing the condition.

In this study, two methotrexate-loaded liquid crystal formulations for topical application showed immunomodulatory effects and induced skin changes in mice with imiquimod-induced psoriasis.

This study concluded that an adapalene nanohydrogel containing Tween-80 could be a promising and stable topical treatment option for acne vulgaris due to enhanced skin permeability and stability compared to other formulations.

In this study, researchers evaluated the binding of keratin-associated proteins and α-keratins to human hair fibers, finding that chemical preactivation significantly enhanced binding to natural hair, while perming altered binding characteristics and increased penetration depth.

This study found that silicone oil-in-water nanoemulsions using nonionic surfactants can enhance silicone oil absorption on hair, suggesting a promising method for hair care applications.

This review discusses various types of hair dyes, their mechanisms of action, molecular structures, application methods, and formulation aspects, but reports no new research findings.

In this study, researchers produced a biosurfactant from yeast that effectively reduces surface tension, acts as a good oil emulsifier, demonstrates antioxidant and antimicrobial properties, and exhibits no cytotoxicity, suggesting its potential use in eco-friendly cosmetic formulations.
