IYKYK! Not to be dramatic, but this product has literally changed my hair. *In the video, this would be the way I use it at night after showering and wake up with smooth soft hair the next morning... NO FRIZZ ! I also use it on damp hair and let it air dry. If I am blow drying my hair, then I just add it to the ends. @kerastase_official #elixirultime #kerastaseaus #ad
