Long hair usually fails at the bottom third. The ends are the oldest part of the strand and they thin out long before the length looks short, which is why hair can be waist length and still look ragged.

Pro Longer is designed for that exact shape of problem. It uses what L'Oreal Professionnel call Filler A-100 along with amino acids, and the idea is to put substance back into a fibre that has worn thin rather than simply coating it. The ends plump up, the lengths read denser, and breakage drops because there is more fibre there to break.

You notice it most in a ponytail. The tail feels fuller in your hand and stops tapering to such a sharp point. It is a maintenance conditioner for anyone growing hair out between trims, and it works alongside a trim rather than instead of one.

Application tips

Lengths and ends only, and be deliberate about it. Gather the hair over one shoulder, apply from the ears down, and pay particular attention to the bottom few centimetres, which are years older than everything above them.

Two minutes, then rinse. Comb through while it is in, not after, and use a wide-tooth comb rather than a brush on long wet hair.

Results

Density is what changes, not softness. The lengths hold more substance in the hand and the hair sits together instead of separating into thin strands towards the bottom.

Less snaps off, simply because there is more of the fibre left to take the strain, and combing gets easier for the same reason. Anyone growing their hair out between appointments is the target, and the effect builds across a bottle rather than landing in one wash.
