KERARGANIC's ONESTEP TREATMENT COLLECTION, composed of a TREATMENT SOLUTION and BLONDE TREATMENT SOLUTION are premium versions of our HAIR REJUVENATION SYSTEM (still available), a potent formulation containing carefully selected fruit, seed, and root extracts and oils known for their healing properties to damaged and weak hair.

While ONESTEP TREATMENT SOLUTION can be applied to all hair colors, ONESTEP BLONDE has been specially formulated to treat and color-tone blonde and platinum hair. While vitamins and essential nutrients treat and repair damaged hair, violet pigments work to do away with brassy and orange tones.
