In this study, researchers created nanowhiskers from crab shell-derived nanochitin that self-assembled into vibrant structural colors within a film. The material, sensitive to environmental changes, shows potential as a food freshness indicator and a sustainable dye for cosmetics due to chitin's biocompatibility.

This study developed the TLMG hydrogel, a seamless in situ biointerface platform, demonstrating robust adhesion, high conductivity, and therapeutic effects for intelligent wound management in complex animal models and human tests, indicating its promise for integrated bioelectronic medicine.

This study found that finasteride-loaded microemulsions using poloxamer 124 significantly enhanced skin penetration of the drug compared to a standard solution, primarily through targeting hair follicles via the transfollicular pathway, with intercluster, intercellular, and transcellular pathways contributing less.

This study found that modern styling cosmetics can significantly alter hair structure through changes in interfacial chemistry and cohesion, particularly when applied to already damaged hair.

This study observed that hair properties vary by ethnicity, influenced by genetic, environmental, and cultural factors, and noted that ethnicity-dependent differences in surface charge and other properties warrant further investigation.

In this study, researchers developed a new sodium alginate/chitosan/Zn2+ hydrogel that showed improved physical properties, antibacterial activity, and biocompatibility, and demonstrated enhanced wound healing and skin regeneration in an in vitro model.

The researchers reported that a 5% Beta vulgaris L. extract nanogel showed better antialopecic activity in testosterone-induced alopecia in mice compared to a 2.5% concentration.

This study suggests that the curly hair phenotype in Mangalitza pigs may involve complex gene interactions related to calcium signaling and lipid metabolism, rather than changes in TRPM2 or CYP4F3 expression.

This study developed a model showing that keratin elasticity in skin may be influenced by electrostatic and bridging interactions between keratin filaments, contingent on the balance of charges in the surrounding medium.

The study explored niosome formulations containing minoxidil and tretinoin and found increased drug stability and controlled release, suggesting potential as an effective drug delivery system for treating hair loss.

Keratin peptides can change hair shape gently without harsh chemicals.

This study found that biologically synthesized silver nanoparticle gel demonstrated excellent wound healing efficacy in rats, surpassing both marketed formulations and ionic silver.

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.

In this randomized double-blind study, 160 adults with alopecia areata showed significant improvements in hair loss severity after using a bioactive peptide cosmetic product that mimics platelet-rich plasma, while the placebo group showed no significant change, underlining the treatment's potential effectiveness.

This study found that differently charged micelles influence the acid-base equilibria of cetirizine by altering its ionization constants, indicating potential interactions with biomolecules of various charges under physiological conditions.

New mutations in hair keratin genes can change hair structure and cause monilethrix, with nail issues more common in certain gene mutations.
