L'Oréal Professionnel Serié Expert Pro Longer Concentrate Treatment for Longer, Thicker Hair 400 ml/13.53 oz
A concentrate rather than a mask, in a 400 ml salon bottle. It goes on thinner and works faster, which suits anyone who is never going to sit around with a treatment on for ten minutes.
The problem it addresses is specific to long hair. Ends wear down to a fraction of the thickness of the hair at the roots, so the length tapers off into something wispy. Filler-A100 penetrates the core of the strand and plumps it back out, so those ends read fuller. L'Oreal Professionnel quotes up to 94% less breakage and 17% fewer split ends.
- Thickens worn ends so long hair keeps its body
- Reduces breakage and visible split ends
- Fast to apply and quick to rinse
- Built for long hair rather than for damage in general
Work it through the lengths after shampoo, leave it briefly, then rinse.
Keep it below the ears. The roots on long hair are rarely the problem, and putting a plumping treatment there only makes the contrast between top and bottom more obvious.
