L'Oréal Professionnel Pro Longer Ends Filler Concentrate 400ml

L'Oréal Professionnel Pro Longer Ends Filler Concentrate is a 400ml weekly rinse-off treatment for long hair with thin, weakened ends. It is the salon-sized concentrate of the Pro Longer range, used once a week in place of your conditioner or mask.

How it works

L'Oréal Professionnel builds Pro Longer on its patented FILLER-A100 technology with an amino acid, which it says penetrates the inner layer of the fibre to thicken the ends and resurface them. You leave the concentrate on the ends for 5 minutes, then rinse. In L'Oréal's instrumental test of the Concentrate with Pro Longer Shampoo and Mask, split ends were reduced by 66%.

Who it suits

Long hair whose ends look thinner, see-through or split compared with the roots, including hair that is grown out or often heat-styled. It suits men and women with long hair.

What it will not do

It cannot make hair grow faster, and it will not join split ends back together permanently: the effect is cosmetic and needs regular use, with trims still recommended. It is a rinse-off treatment, not a leave-in, and it does not replace heat protection.

Good to know

400ml bottle, enough for many weekly treatments. Use it in place of your conditioner or mask on treatment days. Ingredient lists can change and vary by market, so the list printed on your pack is the final reference.

• L'Oréal Professionnel Pro Longer Lengths Renewing Mask - the mask for the weeks you do not use the concentrate
