Thank you for viewing. Brand new, unopened. I received this as a gift from the company in June 2025. From the official website: A leave-in scalp and hair treatment that leads to hair with density, volume, shine, and manageability. How to use: After towel-drying, apply an appropriate amount (about 10-15 pumps) evenly to the entire scalp. Apply one pump at a time with your fingers to prevent dripping. Insert both palms into the scalp from the sides (near the ears) so that they are in contact with the scalp, and blend from the sides to the front while rotating your palms. Apply in the same way to the back. Spray an appropriate amount (about 3-5 pumps) to the entire hair. Run your hands through your hair as if lifting it up, and spread and blend it throughout your hair. - Brand: Kérastase - Model Name: Densifique - Contents: 100ml - Type: Serum Body/Refill...Body *Price reduction not possible.
