Brazilian Blowout Ionic Cleanser is a revolutionary new pre-treatment that removes all buildup in as little as one wash! This new Step 1 pre-treatment to a Brazilian Blowout service essentially makes the Anti-Residue Shampoo obsolete. Anionic cleansing agents draw out and dissolve chlorine, product buildup, and hard water minerals. It does this by unblocking the cuticle without removing hair color. Brazilian Blowout Ionic Cleanser saves the stylist 10 + minutes off the front end of a Brazilian Blowout treatment. Includes only Brazilian Blowout Ionic Cleanser Step 1 16oz.
