ISO's exclusive, patented, thio-free formula utilizes Isohaline, a naturally derived waving agent. Isohaline penetrates more deeply and evenly into the hair than conventional waving agents without aggressively lifting the cuticle. Since the internal structure and integrity of the hair is not disrupted, there is no need for conditioning additives that can hinder the perming process. The result is resilient curls and healthy hair.
