Coco & Eve’s Miracle Hair Elixir, a serum that leaves my naturally curly hair looking healthier and shinier with one drop, has been a success in the face of frizz, particularly in spring and summer humidity. The serum is packed with vitamins C, E, and K, which boost shine and hyaluronic acid, which helps hair retain moisture. It also provides heat protection up to 428 degrees Fahrenheit, making it safer for hair use. The product is currently being sold for $25 by PEOPLE with the code SPRING15.
