Inspired by the Japanese tradition of yu-su-ru—the art of strengthening hair through ritual—the Izumi Tonic Strengthening Conditioner System restores resilience, softness, and vitality to fragile, weakened hair.
Infused with Izumi Tonic, a powerful blend inspired by rice water, this lightweight yet deeply fortifying conditioner works to strengthen hair fiber from root to tip, improving resistance to breakage while enhancing smoothness and shine. Hair feels instantly softer, more manageable, and visibly healthier—without heaviness.
Designed to complement the Izumi Tonic cleansing ritual, this conditioner seals the cuticle, reinforces the hair structure, and leaves strands silky, supple, and renewed with each use.
Usage
Cleanse hair by applying the Strengthening Shampoo System. Rinse carefully and proceed by using the Strengthening Conditioner System or Strengthening Treatment System. To complete the routine, apply the Thickening Serum on lengths.
