Pro Tip from Steffan Tricoci, Sr. Education Manager Kérastase:
"Before going to sleep, massage into lengths and ends on dry hair and leave it in overnight. After applying, braid hair in two sections. Take the braids out in the morning for beautiful beach waves."
Beauty Hack: Apply to mid-lengths and ends, put hair in a braid or heatless curls overnight, and wake up to gorgeously styled, nourished hair.
