Kristin Ess's lightweight shine hair care bundle includes a 1.7oz serum and an 8.45oz leave-in conditioner spray that work together to smooth, strengthen, and illuminate all hair types. The serum instantly tames frizz, locks in moisture, and creates a luminous, smooth finish on strands. Its versatile lightweight formula can be used on both wet and dry hair to enhance shine and moisture when blow drying, creating sleek styles, or simply air drying. The leave-in conditioner detangles, softens, and seals in moisture while adding shine. Its proprietary "Zip-Up Technology" strengthens hair, smooths damaged cuticles, and helps protect against environmental damage and color fading. The leave-in spray restores moisture to revitalize dull hair and can be used by all hair types. Its lightweight formula won't weigh hair down and can be applied to wet hair before blow drying or air drying. Used together, these products provide comprehensive smoothing, protection, shine enhancement, and moisture locking for all hair types and styles.
