Brazilian Blowout FREE Smoothing Base Lissant 34 Oz Brazilian Blowout Free Professional Smoothing Base is part of an innovative two-part smoothing system, formulated without formaldehyde, that effectively smooths and eliminates frizz for up to 12 weeks. Combined with the Brazilian Blowout Free Professional Smoothing Activator, patent-pending technology temporarily weakens disulfide bonds and disrupts weaker bonds on the keratin structure, manipulating these bonds into straight alignment without damage. As a result, the hair takes on a long-lasting, smooth, and frizz-free shape while maintaining strength and elasticity, without affecting color treatments.
