Design Freedom Acid is an acid perm that provides long-lasting natural body and strong, resilient curls. Why Is It Different? Design Freedom Acid perm gives you creative flexibility. Choose natural processing for softer curl and style support or dryer processing for firmer curls and extra body. Design Freedom contains the exclusive Pi-Complex waving lotion that protects the hair during processing by adding conditioners to the hair. These conditioners reflect light, which gives the hair a healthy shine and smooth luster. Also, AHA enriched neutralizer with GFE leverages natural grapefruit acids to lock in curl while providing both shine & manageability. Who Is It For? Design Freedom Acid is ideal for normal and tinted hair (up to 20 volume).
