L'Oréal Professionnel Série Expert Pro Longer 10-In-1 Professional Cream 150ml is a leave-in, multi-benefit treatment designed for long hair that needs reinforcement at the lengths and ends. Formulated with the brand's patented Filler-A100 technology and amino acids, the lightweight cream works inside the hair fibre to plump, smooth and protect — leaving longer hair visibly healthier, stronger and easier to style.

Key ingredients
- Filler-A100 technology — patented L'Oréal complex that helps plump and reinforce the hair fibre
- Amino acids (arginine, serine) — strengthen and reconstruct the hair core
- Panthenol (Pro-Vitamin B5) — adds moisture and improves elasticity
- Lactic acid — helps smooth the cuticle and condition the lengths
Who it's for
Best for women and men with long hair — particularly hair that has been heat-styled, coloured or grown out from previous chemical services and now shows fragile mid-lengths and ends. Suitable for all hair types: fine, medium and thick. Works well as the everyday leave-in for anyone investing in length retention.
How to use
- Shampoo and condition as usual, then towel-dry the hair until just damp.
- Dispense a hazelnut-sized amount (more for very long or thick hair) into the palm.
- Distribute through the mid-lengths and ends, avoiding the roots if hair is fine.
- Do not rinse. Comb through, then blow-dry or air-dry as usual.
