- The original wearable styling conditioner. Sebastian Potion 9 wearable styling treatment. To restore hair’s natural condition, protect, enhance manageability and renew shine. In 1990, when John Sebastian and Geri Cusenza took a trip to the Amazon rainforest, they discovered unknown plants. Bringing back samples at home they were inspired to create a breakthrough formula: a magical cream-gel infused with renewable and sustainable botanical extracts. With Potion 9, Sebastian created an original category for the hair industry: wearable treatments. Even today it remains one of the most loved products in salon and at home. An all time classic. Apply Potion 9 to damp or dry hair. Blow- or air-dry for silky, touchable looks, or use hot tools for refined curls. On dry hair, reapply to add texture and control. Apply anytime for an instant style boost.
