For damaged hair in need of repair, Moroccanoil® Restorative Hair Mask is a 5-7-minute treatment for use on hair damaged by chemical treatments or heat styling. Its high-performance formula contains argan oil, shea butter, and vegetable proteins that help fortify hair, increase elasticity, and promote a healthier look and feel. Use once a week and less frequently as hair improves. How to use: For best results, after shampooing, apply a generous amount of Restorative Hair Mask all over hair and massage a little into the scalp. Leave on for 5-7 minutes. Rinse well. Use regularly on chemically compromised hair and decrease usage as hair's texture and elasticity improve. For thick, coarse hair, mix about 1 teaspoon of Moroccanoil Treatment with Restorative Hair Mask for added shine and elasticity.
