In this study, researchers used atomic force microscopy to evaluate mechanical stiffness across different skin layers in six participants, finding the highest stiffness in the epidermis and lower stiffness as layers progress to subcutaneous tissue, enhancing understanding of skin's physical properties and aiding future research.

This study found petroleum ether to be more effective than methanol at extracting β-sitosterol from Eclipta alba, with higher concentrations detected using HPTLC and HPLC methods. The extracted materials contained metals within safety limits.

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 study found that glycylglycine treatment improved hair softness by enhancing hair alignment and altering internal fiber properties among Japanese women with typically coarse hair.

This study found a negative correlation between lead and calcium levels in the scalp hair and finger nails of exposed and unexposed males, with variations suggesting these tissues can reflect metabolic changes over time.

This study found that enzyme depilation of lambskins can cause damage due to the removal of collagen VI, suggesting the need for a protease that avoids this interaction for successful application.

This article discusses the use of atomic force microscopy for examining human hair surfaces in dermatology, cosmetics, and forensic science, but presents no new research findings.

In this study, researchers found that hair fibers exposed to bleaching and UV irradiation displayed significantly more damage, including increased adhesion and surface heterogeneity, compared to untreated hair, highlighting a synergistic degradation pathway affecting the hair cuticle's integrity.

In this study, researchers observed that patients with Alopecia Areata had significantly lower serum zinc and higher copper levels compared to healthy controls, indicating a disrupted zinc-copper balance that may contribute to the disease's pathogenesis.

This study introduced a novel method that uses upright structured illumination microscopy and atomic force microscopy to map the mechanical properties of thick living tissue slices, revealing the intricate mechanical heterogeneity of mouse skin and effects of preservation techniques on tissue stiffness.

In this study, researchers observed that even a single session of hair dyeing can damage hair fibers, with significant worsening of mechanical properties and protein composition after three or more consecutive treatments, emphasizing the need to consider the cumulative impacts of dyeing on hair health.

This review summarizes techniques like Raman spectroscopy, nanoindentation, and small-angle X-ray scattering to explore the biophysical interactions in collagen fibers, aiming to enhance understanding of fibroblast behavior and mechanisms involved in organ fibrosis and healing processes.

In this study, Hibiscus rosa-sinesis flower extract was found to contain 0.33% quercetin according to HPTLC analysis and 0.37% according to HPLC. Heavy metals measured were within acceptable limits, supporting the standardization of the plant material for efficacy and safety testing.

This study used Density Functional Theory to calculate finasteride's molecular properties, finding the GGA/PW91 method aligns well with experimental data and identifying key reactive sites for chemical interactions.

This study quantitatively determined zinc concentrations in several leafy vegetables from Tudun Wada-Makera, finding that Amaranthus tricolor had the highest zinc concentration and Brassica olaracea the lowest.

This review updates on various methods for hair and scalp examination, encompassing non-invasive, semi-invasive, and invasive techniques, and reports no new results.

In this study, UV-light at 254 nm and Polyquaternium-7 treatment were found to affect the mechanical properties and surface structure of hair.

This study found that applying hair conditioner during a permanent wave process in the middle rather than early or late improves tensile strength, hydration, and maintains healthier hair cuticle structure.

Applying conditioner mid-treatment reduces hair damage during perms.

In this study, applying hair conditioner during the middle of a permanent wave operation resulted in better tensile strength, hydration, and cuticle health compared to other application times.

This study found that Polyquaternium-87 significantly reduced friction forces on hair surfaces treated with various shampoo formulations, highlighting its potential for improving hair care products.

This study found that zinc, copper, and chromium levels were significantly lower in the hair of Korean individuals with schizophrenia compared to healthy individuals.

This study found a correlation between zinc levels in hair and serum, and alkaline phosphatase activity in acne phlegmonosa and alopecia areata patients.

This study suggests that abnormal levels of zinc, copper, and iron in serum or hair may serve as auxiliary and prognostic tests for various skin diseases, though further research is necessary due to conflicting data.
