Kérastase Résistance Extentioniste Serum supports healthy hair growth right from the scalp. This lightweight, leave-in treatment strengthens the roots, boosts scalp vitality, and helps hair grow longer and stronger. Creatine R and Ceramides work together to fortify the hair fiber and reduce breakage. Use it regularly to create the ideal foundation for your hair to reach its full length potential. Directions: Use 2–3 pipettes on towel-dried hair. Apply directly to the scalp, section by section. Massage gently with fingertips to stimulate circulation and distribute the serum evenly. Do not rinse. Use 2–3 times per week.
