L'Oréal Professionnel Paris Pro Longer Thickening Conditioner — 250 ml for Fine, Long Hair | Reduces Split Ends & Adds Volume

L'Oréal Professionnel Pro Longer Thickening Conditioner is a salon-strength conditioner that targets thinned ends to reduce the appearance of split ends while adding body and shine to fine, long hair.

If you have long hair that looks thin at the tips or breaks easily, this conditioner is formulated to rebuild and visually thicken lengths. Infused with Filler A-100, a concentrated filling molecule, plus amino acids, the formula is designed to resurface the hair fiber and reinforce fragile strands. Clinical metrics reported by the brand show a 20% reduction in split-end appearance and up to 64% more volume when used appropriately as part of the Pro Longer routine.

How does this conditioner make thin ends appear fuller?

The Filler A-100 ingredient targets weakened areas by filling micro-gaps in the hair fiber to create a smoother, thicker surface. Amino acids complement that effect by strengthening fragile cuticles, helping lengths look denser and healthier without weighing hair down.

• Filler A-100 resurfaces hair fibers to add visible thickness
• Amino acids reinforce strand structure to reduce fragility
• Light, non-greasy formula preserves natural movement and volume

Will it actually reduce split ends and breakage?

The conditioner is formulated to nourish and protect lengths, addressing the visual signs of split ends and reducing breakage when used regularly. Results depend on hair condition and regimen, but brand testing reports a 20% reduction in the appearance of split ends with consistent use.

• Targets thinned tips to minimize visible splitting
• Nourishes fibers to lower mechanical breakage during styling
• Works best combined with Pro Longer Shampoo and Mask for cumulative benefits

How should I use it for best results?

Apply the conditioner to clean, towel-dried hair, focusing on mid-lengths and ends. Rinse immediately for light conditioning, or leave on for 1–2 minutes for deeper nourishment. Regular use after shampooing helps maintain stronger, shinier lengths over time.

• Use after shampooing on damp or towel-dried hair
• Distribute evenly through mid-lengths and ends, avoiding roots if you want extra lift
• Rinse after application; leave 1–2 minutes for an intensive boost

Can this conditioner add volume without making hair heavy?

Yes—its formulation aims to thicken the hair fiber while remaining lightweight, so fine hair gains body and definition. The product claims up to 64% more volume when incorporated into a full Pro Longer routine, delivering fuller-looking hair that still moves naturally.

• Light-conditioning base preserves bounce and lift at the roots
• Filler A-100 adds tangible thickness to strands rather than coating them
• Pair with volumizing styling products for enhanced root lift

Who is this for: L'Oréal Professionnel Pro Longer Thickening Conditioner is designed for people with long, fine or thinning ends who want to reduce visible split ends and gain fuller-looking lengths. It’s ideal for hair that needs both strengthening and light resurfacing without excess weight. For best outcomes, use it as part of the Pro Longer system—shampoo, conditioner and mask—to combine filling, strengthening and nourishing steps into one targeted regimen.
