This compact 2.5 fl oz treatment comes from KÉRASTASE's Genesis collection and is built to restore resilience and manageability to normal-to-dry hair that suffers breakage. The formula blends edelweiss native cells with ginger root actives to help fortify the hair fiber while delivering softness, shine, and easy detangling without heaviness. Use it after shampooing as a fast rinse-out conditioner to smooth the cuticle, add body, and reduce the appearance of split ends.

How does this conditioner strengthen hair without weighing it down?

The product uses targeted fortifying ingredients that bond with the hair fiber to improve tensile strength while remaining lightweight enough for fine or normal-to-dry textures. It seals the surface for improved combability and leaves hair soft rather than flattened.

• Key actives: edelweiss native cells and ginger root to reinforce fiber integrity
• Light emollients that condition without heavy residue
• Formulated to preserve volume while enhancing softness

Will this conditioner help with detangling and reducing breakage from brushing?

Yes—its slip-enhancing formulation makes combing easier immediately after application, which reduces mechanical stress from brushing. Improved manageability lowers the chance of hair snapping during styling and everyday grooming.

• Instant detangling action for smoother brush strokes
• Helps prevent split ends by smoothing the strand surface
• Recommended for use after Genesis shampoo for best anti-breakage results

How should I use it for best results and how long does it stay effective?

Apply to clean, towel-dried hair and leave on for two to three minutes before rinsing thoroughly. As a rinse-out conditioner its benefits are immediate; regular use within the Genesis routine maintains ongoing fortification and hydration.

• Suggested application: after shampoo on damp hair, 2–3 minutes dwell time
• Rinse well to avoid buildup and maintain natural volume
• Pair with Genesis shampoo and serum for cumulative strengthening effects
