Fibroin: Fibroin makes up the bulk of silk fibers and is responsible for its strength and resilience. When you use a silk scrunchie made from 100% silk, the fibroin in the fabric provides a smooth and frictionless surface that is gentle on the hair. This reduces the risk of hair breakage, split ends, and tugging, which can occur with regular elastic hair ties.

Sericin: Sericin is a protein that coats the fibroin in the silk fibers and serves as a protective layer. It has natural adhesive properties that help keep the silk fibers together in the cocoon. When silk is used as a hair accessory like scrunchies, sericin can provide a soft and smooth surface that helps minimize frizz and static, promoting smoother and shinier hair.
Benefits of the proteins in silk for hair:
A. Moisture retention: Silk has the ability to absorb and retain moisture, which can be beneficial for the hair. When you use silk scrunchies, the fibers help preserve the hair's natural oils, preventing excess drying that can occur with other hair ties. This helps to keep the hair hydrated and less prone to damage and breakage.
B. Hair protection: The proteins in silk can form a protective barrier around the hair shaft, shielding it from environmental pollutants and UV rays. This protection can help prevent damage to the hair, such as dryness and brittleness, which can occur due to exposure to the elements.
C. Allergy-friendly: The proteins in silk, particularly sericin, have hypoallergenic properties, making silk scrunchies a suitable option for individuals with sensitive skin or allergies. They are less likely to cause irritation or allergic reactions on the scalp or skin.
D. Smooth and soft texture: Silk has a luxurious and smooth texture that reduces friction on the hair. This means that when you tie your hair with a silk scrunchie, it glides over the strands rather than rubbing against them. This gentleness helps to minimize hair breakage and damage.
Overall, the proteins present in silk, particularly fibroin and sericin, contribute to the hair-friendly properties of silk scrunchies. They can help maintain hair health, reduce damage, and promote a smoother and shinier appearance, making silk scrunchies a preferred choice for those who want to take extra care of their hair.
