Potential of Silk Proteins in Cosmetics

This study developed a biobased copolymer called SELP::KP, showing improved hair strength, elasticity, and conditioning properties while being a safer alternative to conventional chemical treatments, based on application to human hair in a laboratory setting.

This review discusses the potential of protein-based cosmetics, including keratin-based particles and fusion proteins, to improve hair properties such as strength and shape, but it reports no new clinical results.

This article reviews how biopolymers are utilized in cosmetics, highlighting their biodegradable and non-toxic properties, recent structural developments, novel applications, and safety considerations in the formulation of skin, hair, and oral care products.

This study found that keratin-based particles were able to recover and enhance the mechanical properties and thermal stability of virgin and overbleached Asian hair, improving its strength and smoothness by around 40%, and demonstrated safety in human skin keratinocytes.

This study found that silk fibroin gel induced more pro-regenerative macrophages and hair follicle stem cells, leading to almost scarless skin regeneration compared to alginate gel.
