The Pro Longer Concentrate treatment helps strengthen your long hair, which is visibly healthier and stronger after application. When used in conjunction with Pro Longer shampoo for long hair, it helps reduce hair damage and reduces breakage by up to 94%. Hair is up to 5 times shinier. The Filler A-100 technology used is patented by L'Oréal Professionnel and works by penetrating the core of the hair to make it fuller and strengthened from within. Works on fine ends or areas where it's needed most.

Usage:

1. Apply to damp hair before shampooing Pro Longer.
2. Leave on for 3 to 5 minutes.
3. Rinse thoroughly.
4. Then wash with shampoo.
