SHELLAC

Safety grade: A

Shellac is a natural resin secreted by the lac beetle that is harvested and processed into a solid ingredient. It's the same substance traditionally used to create a shiny finish on wood furniture and is commonly found in nail polish.

Shellac is used in cosmetics to create a protective, glossy film on the skin or hair, improve product texture, control thickness, and help hair stay in place throughout the day.
