Brazilian Blowout Smoothing Activator 34 oz Brazilian Blowout Free Professional Smoothing Activator is part of an innovative two-part smoothing system, formulated without formaldehyde, that effectively smooths and eliminates frizz for up to 12 weeks. When combined with the Brazilian Blowout Free Smoothing Base, patent pending technology engineered to work at the molecular level, temporarily weakens disulfide bonds and disrupts weaker bonds, manipulating them into straight alignment without damage. As a result, the hair takes on a long lasting, dramatically smoother shape without compromising hair strength and elasticity and won't alter color treatments. Benefits: Customizable for any Style Great for all Hair Types No Wait Period Required Less Work and Effort Cuts Blow Dry Time Blend Extensions Seamlessly How to Use: Rinse the hair thoroughly with water (no shampoo), then apply the Smoothing Activator evenly to the damp hair. Leave it on for about 5 minutes to activate the treatment, then rinse again thoroughly.
