Patented Filler A100 Technology: Functions within the hair core like a "micro-plumping gel or structural cement crater-filler"; this exclusive molecule penetrates the inner cortex to deeply expand and thicken the damaged fiber from within. The real result in the mirror is hair ends that regain their robust, uniform density, eliminating that frustrating "thin, wispy ends" look.

Structural Amino Acids: Act over the long hair shaft like "internal steel reinforcing bars"; they rebuild fractured protein links broken by chemical processing or styling tools, leaving the strands highly resistant to future split ends and environmental friction

Ends Volumizing & Plumping: Targets the last 20cm of the hair strand, visibly filling in and thickening thinning, weak ends.

High-Definition Anti-Breakage: Creates a protective layer over long hair fibers, significantly reducing mechanical snap during combing.

Instant Detangling & Silkiness: Imparts pristine softness and a velvet shine, making long hair exceptionally easy to manage and style.

Weightless Conditioning Matrix: Intensely hydrates dry hair sections without creating heavy oiliness or flattening natural root bounce.

During every standard wash cycle as an essential conditioning step if your hair is long or if you are trying to grow it longer while battling thin, splitting ends.

As a protective primer to soften and immunize long hair fibers before executing blow-drying or heat-styling protocols.

For external, cosmetic use on hair lengths and bottom ends only. Do not apply directly to the scalp.

Avoid contact with the immediate eye contour area; if contact accidentally occurs, flush immediately with fresh water.

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

Step 1: After cleansing thoroughly with shampoo, towel-dry your hair using the gentle patting method, leaving it uniformly damp.

Step 2: Dispense an adequate amount of conditioner (hazelnut-sized) and distribute evenly across the mid-lengths and ends (strictly avoid the scalp and roots).

Step 3: Let the clinical formula process on your strands for 2 to 3 minutes, then rinse completely with cool or lukewarm water to seal in the shine.

Q: Does this conditioner act as a chemical relaxer or flat straightener?
A: No, absolutely not. L'Oréal Professionnel Pro Longer relies entirely on patented Filler A100 infrastructure and protective amino acids to reconstruct and safely plump the fiber; it contains no chemical relaxers or formaldehyde and does not change your native molecular hair pattern.
