Curl-Defining WhipVirtue Curl Defining Whip is a hydrating cream that delivers touchable hold, fights frizz, and amplifies curl formation. It provides lightweight definition for bouncy curls and waves without the crunchy, sticky after feel. Our proprietary Alpha Keratin 60ku not only repaves damaged cuticles and refills microscopic cracks in hair, it also protects against humidity, heat, and environmental damage.
