Step two, and the one that decides whether your work is still there next week. Bond Lock closes the bonds Bond Flex opened, reforming and stabilizing lashes and brows in their new shape through controlled oxidation. Paired together the two steps give you the same lift on wildly different lash types, which is what turns a good result into a repeatable one. One airless bottle covers around 40 services.
