ISO Option Damage-Free Perm Wave - #1 (Normal/Previously Permed)

ISO Option 1 is a thio-free waving option for normal and previously permed hair. It is designed to build definition through separation and create loose, free-moving texture with a soft feel.

Best suited for:

- Normal, non-colour-treated hair
- Previously permed hair
- Fine to medium texture
- Normal to moderately porous hair

Result: Increased body, slight wave and minimum curl.

Timing: 20 minutes with built-in stop action.
