TLDR Natural polymers can protect, repair, and promote hair regrowth.
The document discussed the use of natural polymers, specifically chitin nanofibrils (CNs) and chitin-derived compounds, in hair care products to protect and repair hair structure. These polymers were noted for their ability to cross-link keratin molecules, repairing broken disulfide and hydrogen bonds, which are crucial for maintaining hair's tensile strength and flexibility. The study highlighted the potential of CNs as a hair regrowth compound, acting directly on the hair papilla. The nanosize of these polymers allowed them to effectively shield hair from environmental damage and cosmetic treatments that typically cause roughness, dryness, and brittleness.
