Treat your hair to a dose of hydration with the Nexxus Emergencee Masque, a restorative treatment that works to transform the resilience of your tresses. Enriched with fortifying ingredients, this powerful moisture surge works to rebuild lost proteins deep within your hair's structure. Concentrated 100% pure elastin reinforces your hair's natural strength by replenishing its inner fibre structure. Reconstructive marine collagen aids the condition of your hair with weightless protection, sealing in strength & hydration to reveal a more responsive & fluid natural beauty to your locks. After using the Nexxus Emergencee Shampoo, press the mask from the middle to the ends of your hair & comb through. Leave for 3-5 minutes then rinse thoroughly. For extremely dehydrated hair, leave in while you sleep & wash out the following morning.
