OGX® Mirror Shine + Argan Oil Smoothing Pre-Wash Gloss is a rinse-out treatment designed to deliver 48 hours of glossy shine*. Infused with argan oil, this lightweight formula helps repair dry, damaged hair while mending up to 40% of split ends* and leaving strands 4x smoother**. Formulated for all hair types, it works as a pre-shampoo gloss to hydrate, smooth, and prep strands for styling. Apply generously to dry hair from shaft to ends. Let sit for 5 minutes then rinse hair thoroughly. Follow with your favorite OGX® shampoo and conditioner. For a deeper treatment, leave on for longer. *when used with OGX® shampoo and conditioner **when used with OGX® shampoo and conditioner vs non-conditioning shampoo
