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.

This review reports that biopolymer-based hydrogels show promise as wound dressings due to their biocompatibility, moisture retention, and ability to mimic the extracellular matrix, though challenges in mass production, safety, and clinical validation remain.

This study compared the effects of three compounds on structural and sensory benefits for bleached hair when applied with or after bleaching, observing that their application may mitigate bleaching-induced damage.

This study found that using cationic and non-ionic polymers during alkaline hair relaxer treatments may help strengthen hair and control swelling, potentially reducing damage.

This study suggests that ethylene and lignoceric acid (C24:0) may promote cotton fiber and Arabidopsis root hair growth by activating the pectin biosynthesis network.

This study found that higher concentrations of topical diphenylcyclopropenone, especially when prepared with acetone, showed better stability over 6 months compared to lower concentrations.

In this study, researchers synthesized biomedical polyurethanes incorporating curcumin and varying PEG content to enhance water solubility and control curcumin release, finding that higher PEG content improved hydrophilicity, swelling, and degradation, while maintaining excellent antioxidant and antibacterial activities, suggesting promise for biomedical applications.

This article provides guidelines and indices for a three-point cantilever bending test to measure mechanical properties of hair treated with both conventional and naturally-derived styling polymers, reporting no new experimental results.

This source highlights the utility of cationic polymers in haircare products for protecting against hair damage from chemical treatments and grooming, and describes how microfluorometry can measure polymer deposition and penetration on hair fibers.

Polyquaternium 7® builds up on hair, improving its look and feel, and AFM is good for measuring these changes.

This study reports the crystal structure of C28H32O5, revealing its monoclinic symmetry, unit-cell dimensions, and molecular conformation.

Keratin-based hydrogels from human hair and wool are promising for wound dressings and are more eco-friendly.

In this study, fluorescence microscopy revealed that a cationic cellulose ether derivative adsorbed onto hair fibers desorbed significantly when treated with sodium dodecylsulfate.

This study found that using natural polyphenol cross-linkers like tannic acid and green tea extract during perm treatments improved perming efficiency, wave maintenance, and hair protection compared to a control group.

This study found that both new and old formulas of DCP for treating alopecia areata resulted in similar hair regrowth, but tolerance was significantly better with DCP in isopropanol.

This study suggests that true binary and ternary inclusion complexes were formed between finasteride and 2-hydroxypropyl-ß-cyclodextrin, with or without the addition of specific polymers.

This study reports a method for fabricating biofunctional polymer fibers by using DNA-programmable cell-free protein synthesis integrated through solution blow spinning, enabling in situ protein production and potential applications in respirators, sampling swabs, and other advanced materials.

This study found that 'smart' peptide hydrogels improved wound healing in a rat model of partial thickness burns, achieving greater wound closure and faster debridement compared to a standard treatment.

This study found that a dietary supplement containing L-cystine, medicinal yeast, and pantothenic acid significantly improved hair growth in women with telogen effluvium over six months compared to placebo.

This review discusses ethosomes as lipid carriers that enhance drug penetration into deep skin layers and underscores the need for advanced research on their pharmaceutical applications, but it reports no clinical outcomes.
