Discover salon-like shine at home with the L'Oréal Paris Elvive Glycolic Gloss Core Spray Serum, a leave-in formula that improves the appearance of dull, limp lengths. Powered by glycolic acid, the spray-in blend envelops the hair in a 2% gloss complex to elevate shine and radiance. The multi-tasking mist feels lightweight and airy, without adding any extra weight to strands. Doubling as a heat protectant, the serum shields hair against heat up to 230°C. Complete with a refreshing fragrance of grapefruit, jasmine and cedarwood, it leaves hair smelling as good as it looks.
