This study found that coconut oil may protect the cuticle of chemically treated hair, which tends to be damaged compared to untreated hair.

This study found that temperature significantly affects the mechanical properties of rabbit hair fibers, with increased tensile strain and decreased breaking strength in humid conditions.

In this study, the use of internal wool lipid liposomes was shown to improve the lipid composition and increase the resistance to breaking in both untreated and chemically treated hair fibers.

This study found that washing hair after reduction in a permanent waving process allows for significant reformation of disulfide cross-links, enhancing the strength and elasticity of hair fibers.

In this study, the authors observed that the combined treatment group showed a significant increase in inflammatory cell density and a higher maximum tensile breaking force in tendon repair by the end of the second month.

This study found that supplementing cat and dog food with PUFA-rich oil improved hair flexibility, brightness, and skin condition, though it also increased serum triglyceride levels, suggesting careful consideration of dosage and fatty acid composition is warranted.

This study investigated the tensile response and morphological changes of different ethnic hair types using AFM, showing variations between virgin, chemically damaged, and conditioner-treated Caucasian hair under different conditions.

In this research, the authors identify coordinated mechanical forces as crucial for hair follicle development in mammals, with contractile, proliferative, and proteolytic activities facilitating the formation and sectioning of epithelial structures crucial for forming a functional tissue.

In this study, researchers introduced a visible-light-mediated intramolecular cycloaddition method that selectively forms 6-azabicyclo[3.1.1]heptanes, suggesting these structures could offer promising new scaffolds for drug discovery and medicinal chemistry.

This study found that in wound-induced hair neogenesis, African spiny mice and laboratory mice exhibit different morphogenetic field formation patterns related to tissue stiffness, suggesting evolutionary developmental biology advantages.

This study found that adding hair fibers to friction materials increased their friction coefficient stability and impact strength while decreasing wear rates, with 1% hair fiber content notably improving performance.

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

This study found that men experiencing long-term symptoms after finasteride use for androgenetic alopecia frequently reported loss of penis sensitivity and anhedonia, among other effects, indicating potential post-finasteride syndrome.

This study found that the mechanical stiffening of the human hair follicle along the first millimeter is linked to changes in the keratin network architecture and composition during keratinization.

This review discusses in vitro methods for evaluating the effects of hair care products on hair fibers, reporting no new results; the authors emphasize the importance of selecting appropriate and accurate equipment for testing.

This study found that African and Caucasian hair contain the most lipids, and depletion of these lipids leads to less water retention and increased water desorption, with Caucasian hair showing improved breaking tenacity after lipid extraction.

This study suggests that using trichotillometry to establish the normal range of shear strain for different hair types could inform diagnostic and treatment decisions for various hair conditions.

This study found that interleukin-10 deficiency in B6 mice led to inflammatory milk production due to maternal stress, causing alopecia and hepatocyte steatosis in pups.

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 used atomic force microscopy to identify significant morphological differences in hair from patients with lichen planopilaris compared to healthy controls, noting more scratches, uneven edges, and pitted scales in affected hair, which may aid future research on the condition.

In this study, researchers used atomic force microscopy to capture and analyze morphological changes in the surface of healthy hair, identifying features such as pitting and rod-shaped macro-fibrillar elements, which could inform future research on hair conditions and care.

This review outlines the role of mechanical forces in the development of sensory organs like eyes and ears, emphasizing insights from recent animal studies and microfabricated organoid systems; it presents no new experimental results.

In this study, children's hair showed statistically higher elasticity than elderly hair, but no significant differences were observed in tensile strength between dietary or oil application groups, or between pigmented and nonpigmented hair.

This study found that the binding and release of BMP-2 from kerateine biomaterials are significantly influenced by pH and salt concentration, highlighting the potential for developing improved bone repair systems.

This review explores the current understanding of hair follicle development and regeneration, emphasizing the molecular pathways involved and the potential for bioengineering hair follicles in vitro to advance hair regeneration strategies.

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.

Human hair's structure makes it tough and resistant to breaking.

In this study, researchers developed a regression model that reasonably predicts consumer-perceived hair breakage using various parameters such as hair smoothness, detangling forces, extensional strength, and hair density among Indian women.

This study found that in models of diabetic wound healing, extracts from the flavonoid and tannin fractions of Ficus racemosa leaves improved wound closure time, increased breaking strength of incision wounds, and exhibited hypoglycemic activity.
