Brazilian Blowout Açai Protective Thermal Straightening Balm is a powerful heat-activated formulation that straightens waves/curls and tames frizz while protecting hair from heat styling and environmental stresses. Humidity resistant. An exclusive Brazilian Super-Nutrient Complex reconstructs and strengthens damaged hair while creating a protective protein layer on the hair shaft to straighten, smooth and seal the cuticle. The end result is straighter, smoother, healthier hair with radiant shine. For a stick straight, just flat-ironed look all day long.
