KÉRASTASE Strengthening Conditioner Genesis Fondant Renforcateur 2.5 fl oz — Detangles & Hydrates

KÉRASTASE Genesis Strengthening Fondant Renforcateur is a lightweight conditioner designed to fortify weakened, breakage-prone hair while detangling and adding hydration and shine.

This concentrated conditioner from the KÉRASTASE Genesis range targets hair weakened by heat styling and mechanical stress. It combines fortifying active ingredients to reinforce fiber structure without weighing strands down, making it suitable for normal to dry hair that needs both moisture and anti-breakage support.

How does this conditioner strengthen fragile or damaged hair?

The formula uses targeted fortification agents to reinforce the hair fiber and reduce breakage caused by brushing and thermal styling. Regular use rebuilds resilience along the hair shaft so strands handle daily styling better.

• Contains edelweiss native cells to support fiber integrity.
• Ginger root helps to strengthen and support hair structure.
• Lightweight conditioners avoid weighing hair down while delivering fortification.

Will it detangle and add moisture without making hair limp?

Yes — the fondant texture smooths cuticles to ease comb-through while providing balanced hydration. It’s formulated to soften and detangle without leaving a heavy residue, preserving lift and natural movement.

• Detangles quickly for easier brushing and styling.
• Delivers moisture that restores softness but maintains body.
• Rinses cleanly to prevent buildup and limpness.

How should I use it for best results in my routine?

Apply to shampooed, towel-dried hair and leave on for 2–3 minutes before rinsing to allow active ingredients to penetrate. For optimal reinforcement, pair with the Genesis shampoo and serum from KÉRASTASE.

• Use after cleansing with a compatible Genesis shampoo.
• Distribute from mid-lengths to ends, avoiding the scalp if oily.
• Combine with the brand’s serum for targeted anti-breakage care.

What immediate benefits can I expect after one use?

After a single application you should notice improved manageability, smoother texture, and increased shine. Repeated use builds greater fiber strength and helps minimize breakage from daily styling and brushing.

• Softer, more manageable strands right away.
• Visible shine and smoother cuticle appearance.
• Reduced tangling for gentler styling sessions.
