If you’re new to the U.S. (it launched here in May), you may not have heard of Mise En Scène yet. However, this brand is hugely popular in Korea, where it has been the number-one hair-care brand for 11 years. This bestseller is a hair serum that is packed with seven different oils—argan, coconut, apricot, olive, camellia, jojoba, and marula. These oils work together to hydrate and nourish your hair, making it stronger, sleeker, and more elastic. Additionally, this serum provides heat protection, making it a must-have for your hair-care routine.
