Thio-free professional perms for body, curl and wave

ISO

Iso Option is a professional perm system built on thio-free waving agents, Isohaline and Isoamine, that penetrate evenly without aggressively lifting the cuticle. The result is body and curl while the hair keeps its strength and shine.

Choose Option 1 for normal or previously permed hair, Option 2 for colour-treated hair, Option 3 for extra-firm curl on resistant hair, or the exothermic Option EXO for long, resistant lengths.

Our guides explain which Option suits which hair and how to care for a new perm.

Your questions, answered

Which Iso Option should I use?
Option 1 for normal or previously permed hair, Option 2 for colour-treated hair, Option 3 for firm curl on resistant hair and EXO for long, resistant hair.
What does thio-free mean?
The waving agents are Isohaline and Isoamine rather than conventional thioglycolate, so the cuticle is lifted less aggressively.
Is it for home use?
It is a salon-strength professional product; a test curl is essential and a stylist is the safer route.
How long should I wait before shampooing?
48 hours after the perm.
