This review categorizes contractile hydrogels by their contraction mechanisms and explores their role in advanced wound management, emphasizing mechanical and biochemical signaling in healing, but also notes challenges like force transmission and clinical applicability.

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 review explores the different types of hydrogels used to repair diabetic ulcers, the mechanisms involved, and the limitations in developing these technologies for clinical use, but it reports no new clinical results.

This study found that using a bicomponent reduction system with TGA and DTDG for hair straightening limited hair damage by forming only thiol groups, while a TGA-only system formed more damaging mixed disulfide groups.

In this study, shampoos containing sodium lauroyl methylaminopropionate showed superior coacervate formation and lubrication on wet hair, outperforming other amino acid surfactants and suggesting potential for creating low-irritation, high-performance hair products.

Keratin peptides can change hair shape gently without harsh chemicals.

In this study, a hydrogel wound dressing infused with tannic acid demonstrated excellent antibacterial activity and promoted effective wound healing in rat burn models, leading to wound closure in 17 days and hair regrowth by day 21.

This study found that microfibrils play a crucial role in shaping permanent waves by thioglycolic acid, and treating damaged hair with hydrolyzed keratin improved both waving efficiency and hair damage.

This review analyzed how the chirality of peptide building blocks affects their self-assembly into hydrogels, comparing structural and mechanical properties of homochiral and heterochiral peptides, and discussed potential biological applications of these peptide systems.

A new method strengthens hair without using harmful chemicals.

This review explores how recombinant protein hydrogels, employing molecular engineering and crosslinking strategies, offer advanced applications in regenerative medicine by mimicking extracellular matrix dynamics and providing enhanced mechanical, environmental, and biological properties.

In this study, the combination of biologically engineered hyaluronic acid and polyquaternium-10 improved hyaluronic acid's retention and moisturizing effects on hair by forming a stable complex that increased binding affinity to keratin.

In this study, researchers developed a simplified and reliable method to prepare human hair shaft samples, achieving over 75% protein extraction efficiency and improved keratin sequence coverage, with the approach showing high reproducibility across different labs and operators.

This study found that soaking raw skin in a saturated lime solution led to widespread cellular dissolution and tissue changes that facilitate dehairing after 4 to 7 days at -18°C.

The hydrogel helps heal diabetic wounds by combining antibacterial, antioxidant, and immune-boosting effects.

This study suggests that specific structural features of minoxidil analogs, such as hydrophobic and hydrogen bond field contributions, are key to enhancing lysyl hydroxylase inhibitory activity, which could inform future hair growth treatments.

This study reports that mutations in human L-PGDS affect the entrance and exit of ligands in its binding cavity, suggesting these residues play a role in ligand interaction processes.
