In this study, a new shading model for hair was developed that better matches real-life light scattering, thanks to detailed new measurements of hair fiber scattering not predicted by existing models.

This study introduced a new hair shading model that more accurately simulates light scattering on hair fibers, capturing effects not predicted by previous models.

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.

This study found that targeting the hair follicle can be increased by using lipophilic drugs combined with surfactant solutions and propylene glycol.

Hair treatments like bleaching increase friction by exposing tiny pores on the hair surface.

This study found that the moisture content of human hair significantly influences the type of fracture under tensile loading, with low or high humidity levels leading to smooth fractures and intermediate humidity resulting in step fractures.

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.

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 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.

This study is the first to document alopecia in Guadalupe fur seals in the Northeast Pacific Ocean, finding that it may result from nutritional stress due to higher sea surface temperatures.

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 study found that using a standardized protocol with microspheres of approximately 1.5 micrometers enhances penetration into hair follicles, particularly when skin is treated with cyanoacrylate skin surface stripping.

This study in neonatal chicks reported that intense sound exposure severely impaired auditory function, but function returned to near normal within 3 days, primarily due to non-hair-cell mechanisms.

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.

In this study, nanoemulsion formulations were found to significantly enhance the skin retention of the antiseptic agent triclosan, with the optimal mixture being a low surfactant concentration, as demonstrated through quantitative and qualitative analysis using tape-stripping and micro CT scans.

This study investigated the mechanical response of the human hair cuticle to strain and found that cuticular deformation directly corresponded with fiber elongation, revealing significant molecular-level changes in disulfide crosslinks but maintained structural stability, highlighting the role of the cuticle in stress resistance.

This study found that UV stabilizers must diffuse uniformly and in high uptake levels throughout hair fibers during humidification cycles to effectively prevent photo-oxidative degradation.

This study found that hair membrane fluidity is low in the cuticle but high in the cortex and medulla, with treatments like ionic surfactants and oleic acid increasing fluidity in hydrated hair; however, dehydration significantly reduces fluidity throughout the hair.

This study found that the fungus Microsporum gypseum enzymatically degrades keratin in human hair, with the sequence of degradation reflecting the keratinization and cystine content of individual hair components in vitro.

This study introduced hair capacitance mapping as a promising technique for assessing hair surface moisture dynamics, revealing that weathered hair loses moisture more quickly than intact hair.

This paper critically reviews recent advances in the use of keratin-based biomaterials, highlighting their potential applications in wound healing, drug delivery, and tissue regeneration due to their biocompatibility, biodegradability, and ability to support cell growth.

The book was the first to focus on the biophysical properties of hair.

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 study found that enzymatic conversion of Arg-51 in S100A3 protein to citrulline promotes homotetramer assembly, potentially increasing Ca²⁺ binding required for hair cuticular barrier formation.

This study describes the presence of holes in hair fibers, absent in hair follicles, likely forming from daily care actions and removal of extractable substances.

This review examines new formulations for delivering 5-α-reductase inhibitors to improve targeted drug delivery in androgenetic alopecia, but reports no new clinical results.

This study found that scalp cooling resulted in visible hair retention in 53% of breast cancer patients undergoing Epirubicin/Cyclophosphamide and Paclitaxel treatment, with factors like hair bulb diameter, shaft diameter, and anagen rate significantly predicting outcomes.

This review article highlights how hair follicle-targeting drug delivery systems enhance therapeutic outcomes and reduce side effects for treating conditions like androgenetic alopecia and acne vulgaris. The authors discuss current formulations and evaluate their performance in both preclinical and clinical settings.

This study found that using henna dye positively affected hair cuticula pattern and diameters compared to undyed hair, though the degree of change may vary based on hair phenotype and condition prior to treatment.

This study found that inhibiting arachidonate 12-lipoxygenase (ALOX12) may enhance hair cuticle maturation by increasing S100A3 protein citrullination and promoting cuticular differentiation in isolated human hair follicles.
