Top Silk Protein-Based Hair Care Products: Benefits of Sericin, Hydrolyzed Silk Proteins, Silk Peptides, and Silk Amino Acids

Did you know that silk contains valuable proteins?

Before silk is processed for textile use, it has a gummy coating that must be removed. This substance, known as sericin, is a pure protein and constitutes about 25% of the weight of silk cocoons. Since the 1980s, researchers have been characterising these proteins, and they have recently gained significant value as active raw ingredients in cosmetics, pharmaceuticals, and biomaterial sciences[1][2].

Understanding Silk Proteins

Sericin is composed of 18 amino acids, including serine, glycine, and alanine. These amino acids form long-chain molecules. For our hair or skin to absorb these molecules, they need to be broken down into smaller peptides or amino acids through a process called hydrolysis. The resulting product is known as hydrolyzed silk proteins. These proteins are moisturising, anti-frizz, and can heal damaged cuticles. They also serve as excellent carriers for other active ingredients in hair care products due to their high water solubility[3][4].

Benefits of Silk Proteins in Hair Care

Silk proteins can be formulated into various hair care products such as serums, shampoos, conditioners, heat protectant sprays, leave-in treatments, and hair masks. These products can easily penetrate the hair shaft and strengthen hair follicles, providing numerous benefits:

  1. Moisturising:Silk proteins help retain moisture in the hair, keeping it hydrated and healthy.
  2. Anti-Frizz: They smooth the hair cuticle, reducing frizz and enhancing shine.
  3. Repair: Silk proteins repair damaged hair by filling in gaps in the hair cuticle.
  4. Protection:They provide a protective barrier against environmental damage and heat styling.
