Virtue Curl-Defining Gel is a memory-building curl perfector with the strength of a traditional gel definer but none of the slick, crunchy side effects. Sheer and smooth, it glides through hair to build, shape, de-frizz, and hold the curls you haveand the ones you never knew existed. All Virtue products contain Alpha Keratin 60ku, a healing protein that’s identical to the keratin that makes up 90% of hair. It repaves and refills keratin, repairing damaged hair with each use.
