Thank you for viewing. Brand new, unopened. I received this as a gift from the company in March 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 so they adhere to the scalp, starting from the sides (near the ears), and work your palms in a circular motion from the sides to the front. Do the same for the back. Spray an appropriate amount (about 3-5 pumps) onto the entire hair. Run your hands through your hair as if lifting it up, and spread the product throughout the hair. - Brand: Kérastase - Model Name: Densifique - Contents: 100ml - Type: Serum Main unit/refill...Main unit. *Price reduction not possible.
