Patented Filler A100 Technology: Functions within the porous hair core like an "internal micro-plumping filler or an intelligent structural crater-repair patch"; this exclusive molecule penetrates deep inside the inner cortex to expand and solidify the thin fiber from within. The real result in the mirror is hair lengths that regain their robust, uniform density, eliminating that frustrating "thin, wispy ends" look.

Structural Amino Acids: Act over the entire length of the hair strand like "microscopic steel reinforcing columns"; they rebuild broken protein links compromised by chemical processes or hot styling tools, leaving the lengths highly resistant to future splitting and friction.

Gentle & Purifying Cleansing: Thoroughly washes away daily city dust, environmental pollution, and sebum buildup without stripping the native lipid barrier of long hair.

Ends Volumizing & Plumping: Targets the last 20cm of the hair strand, structurally reinforcing weak, thin, and translucent ends.

High-Definition Anti-Breakage: Enwraps long fibers in a protective shield, significantly reducing structural snapping during everyday styling and brushing.

Weightless Elastic Matrix: Delivers pristine softness and natural root bounce, keeping the full hair length fluid and entirely free from heavy buildup or caking.

During every standard wash cycle as the non-negotiable "Step 1" if your hair is long or if you are actively growing it longer while battling brittle, splitting ends.

As a perfect preparatory cleanser to fully de-gunk the hair shaft, preparing the cuticles to absorb the active ingredients of subsequent masks or conditioners.

For external, cosmetic use on the hair and scalp only. Do not swallow.

Avoid contact with the immediate eye contour area; if contact accidentally occurs, flush immediately with an abundant volume of fresh tap water.

Keep the bottle tightly closed and store in a cool, dry place away from direct high heat or intense solar rays.

It is recommended to perform a patch test on a small hair strand prior to full initial application to rule out any rare skin sensitivities.

Step 1: Wet your hair thoroughly with lukewarm water (avoid hot water as it strips lipids and accelerates cuticle dehydration).

Step 2: Dispense an adequate amount of shampoo and massage firmly into the scalp using your fingertips (never your nails) to stimulate localized micro-circulation, working the creamy gel into a rich lather across your lengths and ends.

Step 3: Rinse completely with fresh water. For maximum structural transformation, follow immediately with the Pro Longer lengths renewing mask.

Q: Is this shampoo completely sufficient to fix severely split and broken ends on its own?
A: The shampoo provides foundational clinical cleansing and primary fiber restoration. However, if your ends are highly compromised, thin, or brittle, we strongly recommend combining it with the L'Oréal Professionnel Pro Longer Mask as an intensive weekly therapy to lock in the absolute best thickness and volume.
