L'Oréal Professionnel Paris Pro Longer Thickening Conditioner for Fine & Thin Long Hair — Reduces Breakage and Visible Split Ends,

L'Oréal Professionnel Pro Longer Thickening Conditioner is a salon-grade conditioner formulated with Filler A-100 and amino acids to thicken hair fiber, reduce the appearance of split ends, and boost volume for thin and fine long hair.

This conditioner targets long hair that shows thinning at the ends. It combines a patented filling molecule (Filler A-100) with strengthening amino acids to resurface and fortify lengths, helping hair look fuller and healthier without weighing it down. Designed as part of the Pro Longer system, it works best when paired with the matching shampoo and mask but is effective on its own as a daily conditioning step.

How does this conditioner reduce split ends and strengthen long hair?

Pro Longer uses a concentrated filling molecule to refill and smooth the hair fiber where it has thinned, while amino acids help reinforce the hair structure. Together they minimize the visible fraying at the tips and restore a smoother, more uniform surface along the lengths.

• Contains Filler A-100 to thicken and resurface hair fiber
• Amino acids to reinforce and renew lengths
• Clinically measured: reduces appearance of split ends by 20%
• Designed for long lengths prone to thinning and breakage

Will this conditioner make my hair look and feel fuller?

The formula is lightweight yet nourishing, so it adds lift and body without heavy residue. In instrumental testing it delivered a measurable increase in volume, making fine strands appear thicker and more voluminous from root to tip.

• Delivers 64% more volume in testing conditions

• Non-greasy finish preserves natural movement

How should I use Pro Longer Thickening Conditioner for best results?

Apply on damp, shampooed hair focusing on lengths and ends. For routine conditioning, rinse after a short dwell; for extra nourishment leave on for 1–2 minutes before rinsing. Use regularly and pair with Pro Longer Shampoo and Mask for a complete regimen.
