A lash lift kit is a comprehensive set of products designed to curl and set natural eyelashes into a more lifted position. Unlike traditional eyelash curling methods, which rely on mechanical tools, lash lifts chemically alter the structure of the lashes, providing a semi-permanent curl that can last for weeks. The kit typically includes a series of solutions—cleansers, lifting solutions, setting solutions, and nourishing agents—along with tools like silicone rods or pads to shape the lashes.
