This unique smoothing formula extends the life of the brazilian blowout as it detangles, conditions and seals the cuticle to lock-in moisture and lock- out humidity. The end result is smooth, frizz-free hair with radiant shine. Acai protective thermal straightening balm is a powerful heat-activated formulation that straightens waves/curls and tames frizzies while protecting hair from heat styling and environmental stress. Humidity resistant.
