L'Oréal Paris Elvive Extraordinary Oil Midnight Hair Serum is a luxurious overnight treatment designed to deeply nourish and rejuvenate dry hair while you sleep. Infused with precious camellia oil, this transformative formula targets the most vulnerable parts of the hair fiber, working through the night when hair is free from external aggressors. The non-greasy, lightweight texture ensures no pillow transfer and leaves no residue, while delivering up to 96 hours of frizz control. Suitable for all hair types-straight, wavy, curly, or coily-this hair serum helps restore softness, shine, and manageability by morning, leaving your hair visibly healthier and beautifully revived.
