OUAI Leave In Conditioner is a multitasking spray conditioner that detangles, hydrates, and fights frizz for all hair types. This Costco two-pack includes two 4.7 fl oz bottles of the brand's bestselling leave-in formula, scented with the signature North Bondi fragrance — a blend of bergamot, Italian lemon, rose de mai, violet, patchouli, and white musk inspired by Sydney's iconic Bondi Beach.

The lightweight, vegan formula repairs dry ends and protects against breakage while adding slip for seamless detangling. It can be used as a pre-heat styling primer before blow-drying or straightening, or as part of a wash-and-go routine. Protects hair from heat damage up to 450°F (232°C), and clinical testing shows it reduces hair breakage by 52% when used with heat. Thicker, coarser, or curlier hair can also apply it to dry hair for added hydration, shine, and flyaway control.

Key ingredients include tamarind seed extract, panthenol (Vitamin B5), Vitamin E, hydrolyzed proteins, baobab seed oil, argan oil, evening primrose oil, and sodium hyaluronate. The formula is free from parabens, phthalates, SLS/SLES, gluten, and animal-derived ingredients, and is not animal tested.
