Biomimetic restoration of the hair f-layer using covalently anchored 18-mea
A novel biomimetic hair-repair platform that restores the natural lipid barrier of Type 4 hair using covalently attached 18-MEA. This approach aims to provide lasting hydration and humidity resistance by rebuilding the hair surface rather than coating it, addressing the root causes of dryness and frizz.
Overview
This innovative hair-repair platform offers a biomimetic solution to restore the natural lipid barrier of Type 4 hair. By covalently attaching 18-MEA, a key fatty acid lost during chemical damage, the solution aims to recreate the hair's native hydrophobic barrier. This technology addresses the root causes of dryness and frizz, providing long-lasting moisture retention and humidity resistance by rebuilding the hair surface rather than merely coating it. The platform promises improved curl definition, reduced moisture loss, and lower fiber friction without buildup or weight.
Technical specifications
Key features:
- Utilizes covalent grafting chemistries including thiol-selective, amine-selective, and photoactivated approaches.
- Restores the covalently bound 18-MEA layer, enhancing moisture retention and reducing humidity-induced swelling.
- Offers a durable solution that outperforms traditional conditioners that rely on temporary deposition.
- Evaluated through spectroscopy, contact-angle measurements, and wash-cycle testing to quantify grafting efficiency, surface hydrophobicity, and durability.
- Aims for a prototype leave-on treatment that is effective, durable, and minimizes buildup, ensuring safety and formulation feasibility.
Technology readiness level
The current development stage is at Technology Readiness Level 3, involving the synthesis of biomimetic 18-MEA derivatives and initial testing on Type 4 hair tresses. The platform is undergoing validation to optimize attachment chemistries and performance metrics.
