| Keratin is a natural fibrous structural protein widely found in animal hair, feathers, nails and skin. It is composed of α-helical structure (α-keratin) or β-folded structure (β-keratin). Its high sulfur content (including cystine) gives it toughness and elasticity. It is often used in the fields of hair care, skin care and biomedical materials, and has the function of repairing, protecting and strengthening tissue barriers. |

1. Repair and protection: fill the defects of hair/skin stratum corneum and enhance the barrier function.
1. Hair care products
• Shampoo/conditioner: repair split ends and improve hair luster.
• Perm and dye repair agent: neutralize chemical damage and reduce hair breakage.
2. Skin care products
• Moisturizer/mask: enhance the skin's ability to lock in moisture and repair dryness barrier.
• Anti-aging products: improve skin elasticity and reduce fine lines.
3. Biomedicine
• Wound dressings: promote wound healing (such as burns and ulcers).
• Tissue engineering scaffolds: used for bone and cartilage regeneration (biodegradable materials).
4. Industrial materials
• Bioplastics: environmentally friendly and degradable packaging materials.
• Textile coatings: enhance fiber wear resistance (such as wool products)
