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 identified a unique concentric double-layered structure in both Japanese and Caucasian SHINAYAKA hair, associated with improved flexibility and elasticity, and developed a succinic acid treatment to enhance these properties.

In this study, high-resolution ultrasound imaging revealed that DHT administration in male C57BL/6 mice leads to increased epidermal and dermal thicknesses and decreased skin elasticity, simulating structural changes associated with Androgenetic Alopecia.

Atomic Force Microscopy is a more accurate way to assess hair damage and the effect of cosmetic treatments.

This study found that treating damaged hair with maleic-modified amino silicone oil created a highly hydrophobic surface, reducing water content and improving hair's mechanical properties and thermal stability.

This article reviews how biopolymers are utilized in cosmetics, highlighting their biodegradable and non-toxic properties, recent structural developments, novel applications, and safety considerations in the formulation of skin, hair, and oral care products.

In this study, a copolymer made from Tung oil and Tung free fatty acids demonstrated improved mechanical and thermal properties for hair repair, with enhanced resistance and flexibility observed in treated bleached hair, suggesting its potential as a sustainable biopolymer for cosmetic applications.

This study found that a sucrose-based crosslinker can effectively straighten hair and maintain durability in high humidity and through repeated washings without affecting the hair's tensile properties or causing surface damage.

This study in diabetic db/db mice found that treatment with the antihypertensive agents minoxidil or nebivolol stimulated elastogenesis and inhibited elastolysis, leading to restored elastic fibers, reduced aortic stiffening, and normalized blood pressure.

In this study, cricket-derived chitin successfully converted to nanochitin, which demonstrated improved physical properties such as higher transmittance and greater modulus compared to crab shell nanochitin.

This study suggests that adjusting the ratios of keratin-associated proteins to keratin intermediate filaments can create keratin/chitosan hydrogels with more consistent gel properties for tissue engineering.

This article reviews applications of optical coherence tomography techniques in medicine, including for diagnosing androgenic alopecia and monitoring blood coagulation, but provides no new clinical results.

This study observed that keratose, derived from human hair, integrated well in mouse tissue and remodeled with collagen, suggesting potential as a non-toxic biomaterial for regenerative applications.

In this study, researchers developed and tested hair gels using pectin from mango and coconut oil as a potential natural treatment for traction alopecia in black women, reporting stability in some formulations and rheological properties that may support their use in innovative phytocosmetics.
