This review explores the complex interrelationships among different properties of natural hair fibers and underscores the need for a holistic taxonomy to improve data interpretation across disciplines, but it reports no new experimental results.

This study found that hair luster decreases with age in Japanese females, primarily due to an irregular increase in fiber curvature which affects hair alignment.

This study used quantitative methods to identify new geometric and mechanical parameters of curly and kinky/coily hair, aiming to improve classification and develop better personal care products for these hair types.

This study introduces a new test using a pendulum device to assess the bending stiffness of hair fibers, which can evaluate the effects of different hair treatments.

This paper presents an RGB video microscopic system to monitor optical properties of hair shafts and follicles in vitro, but reports no new clinical results.

This study developed finite element models to examine skin's biomechanical properties, finding that structural heterogeneities like Rete ridges and hair follicles create distinct stress and strain patterns that may influence mechanosensation and skin integrity.

This study identified new geometric and mechanical parameters for curly and kinky/coily hair, which may inform more effective personal care products tailored to these hair types.

This study demonstrates that (9+2) topological patterns derived from fractal fiber sets exist, with nine total patterns and only two being independent or fundamental.

This research suggests that geometric classification of hair into fewer groups may be more reliable and useful for studying hair characteristics, rather than racial descriptions, especially in medical and forensic applications.

This study analyzed the geometric and electronic properties of baicalin conformers, finding that BCLa2TT and BCLa1TT conformers exhibit high stability in aqueous solutions and are favorable for interactions with positively charged species.

This study observed that hyaluronan's transformation into HA·3Ca and its hydrate increases drug absorption by changing its molecular characteristics, influenced by zwitterionic character and acidic pH.

This study determined the molecular structure of finasteride and its related crystalline forms, highlighting different hydrogen-bond interactions and structural configurations in various crystalline complexes.

This study highlights confocal microscopy as a promising, minimally invasive tool for assessing hair morphology and internal structures, making it valuable for cosmetic hair assessments.

This study used Density Functional Theory-based computational methods to analyze finasteride's molecular properties, finding that the GGA/PW91 method closely matches experimental data for vibrational frequencies and geometric parameters.

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 found that finite element analysis-guided design improved bubble microneedles' controlled tip separation and insertion strength, supporting effective transdermal and sublingual drug delivery.

This study developed a co-design framework using finite element analysis to optimize bubble microneedles, achieving controlled tip separation and effective drug delivery through the skin and mucosa while maintaining insertion strength.

This study reports a good correlation between the curvature of human eyelashes and the displacement of the neutral axis, influenced by the non-uniform thickness of the outer cuticle layer.

This study characterized the stress-strain properties of the human scalp and found that its stiffness increases significantly with load, providing valuable insights for planning scalp surgery procedures.

This small study reports that a 6-group geometric classification method is more reliable for classifying human hair curl, although a digital system could further reduce errors.

This study found that hair treated with shampoo containing water-soluble silicone demonstrated smoother sliding and better detangling, compared to shampoo with water-insoluble silicone, due to differences in conditioning film formation.

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

This study found that the pH-sensitive hydrogel HECHA13, containing isoliquiritigenin, effectively inhibited the growth of Propionibacterium acnes and showed promise for transdermal delivery in acne treatment.
