This review examines hair cosmetics, including shampoos and conditioners, for their formulations and effects, but reports no new clinical findings; it emphasizes the importance of dermatologist knowledge in treating diverse hair conditions.

In this study, researchers found that Asian hair contains more integral lipids than European or African hair, which may protect it better from UV-induced damage.

Keratin peptides can change hair shape gently without harsh chemicals.

This study observed that the reproductive phenology of Ficus species in Northern Thailand varied seasonally, with female trees producing the most figs during the rainy season, while male trees' fig production peaked earlier.

This study demonstrates that spatially resolved IR and Raman imaging can effectively reveal the molecular structure and composition of untreated human hair, providing insights into its chemistry and structural integrity.

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 study found that bio-based waterborne polyurethanes derived from castor oil may offer effective hair-styling performance without skin irritation and appear to be safer for the environment compared to traditional hair sprays.

This study found that both everyday physical and environmental stresses, as well as chemical treatments, contributed to hair damage, with cuticle layers being more noticeably affected.

This study observed that repeated perm treatments decrease disulfide bonds in hair due to their conversion largely into cysteic acid, affecting the waving efficiency depending on the reduction agent used.

This study found that keratin-based particles were able to recover and enhance the mechanical properties and thermal stability of virgin and overbleached Asian hair, improving its strength and smoothness by around 40%, and demonstrated safety in human skin keratinocytes.

This literature review suggests that early and aggressive intervention may improve outcomes for avulsive ballistic facial injuries, although further comparative studies are needed.

This study's molecular dynamics simulations suggest that electrostatic interactions mainly stabilize peptide binding to human hair keratin, with the protein's dielectric constant significantly affecting free energy calculations.

This study demonstrated that molecular dynamics simulations of keratin could effectively model the mechanical properties of hair, aligning well with experimental data, especially when conducted in vacuum conditions.

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

This review summarizes clinical trials and comparative studies showing that latanoprostene bunod 0.024% is effective and safe for reducing intraocular pressure in patients with open-angle glaucoma or ocular hypertension, detailing its mechanism and side effects while considering its therapeutic role.

This article reviews various aspects of shampoos, including preparation methods and commercial value, but reports no new experimental results, instead focusing on patents and product evaluation criteria.

This case report describes a 49-year-old woman with Sweet syndrome who experienced complete resolution of skin lesions after a prednisone treatment regimen.

In this study, researchers used computer-generated models to demonstrate that subtle changes in hair diameter, density, and style significantly affect perceptions of age, health, and attractiveness.

This study found that bleached hair showed optimal protein structural integrity and tensile strength at pH 5, with significant changes in cross-linking, water content, and diameter at more alkaline or acidic levels.

This study found that coconut oil impedes hair hydration more effectively than soybean oil by penetrating deeper, and suggested a new model for intermediate filament assembly in hair.

This review discusses the limitations of current hair classification systems and highlights the need for standardized reporting of key hair characteristics to improve study comparisons; it reports no new results.

Polyquaternium 7® builds up on hair, improving its look and feel, and AFM is good for measuring these changes.

This study investigated various proteins as eco-friendly hair perming agents for Asian hair and found that bovine serum albumin and keratin achieved perming results comparable to commercial products, while also increasing hair moisture, indicating a protective effect during heat styling.

This study found that chemical hair straightening significantly reduced hair curl and improved smoothness and shine, but did not significantly affect transverse fissures or split ends, indicating potential benefits with some side effects.

In this study, Trf1 genetic deletion in mice, including those with cancer-prone mutations, was shown to not affect overall viability and cause only mild effects, while being necessary for tumor formation, suggesting a potential therapeutic window for Trf1 as an anti-cancer target.

This review focuses on the roles of amino acids, peptides, and proteins in cosmetics, highlighting their importance in skin health and their potential for development in personal care products due to their unique properties and biocompatibility.

This study found that polyquaternium-68 at pH 9 achieved the greatest hair deposition, while polyquaternium-44 demonstrated the best wash resistance at pH 6.

This study found that coconut oil significantly increased the tensile strength of twisted hair fibers due to its ability to penetrate the hair core, in contrast to mineral oil.

This article discusses the substantial presence of advertising material in the original serial numbers of "The Pickwick Papers," accounting for almost one third of the content, but presents no new results.

This review discusses the causes of hair shaft abnormalities and highlights the role of cosmetic products in treating hair disorders, though it reports no new clinical findings.
