INOA Single Process
gentle, all-over color
The ammonia-free version of our single process service — full, all-over color with less odor and less scalp sensitivity.

How It Works
All the coverage, none of the ammonia
INOA Single Process delivers the same full, all-over color result as a traditional single process, using an ammonia-free, oil-based delivery system instead.
It's especially popular with clients who've had scalp sensitivity or a strong reaction to traditional permanent color in the past.
