This product didn’t work for my hair. My loss is your gain! I have two bottles of Olaplex Dry Shampoo. One has been used twice, and the other maybe used once. They have been sitting in my hair basket with other products, so might show a few scuffs, etc., but they are full and new! From the Olaplex website: The Nº.4D Clean Volume Detox Dry Shampoo, infused with patented OLAPLEX Bond Building Technology, is a healthy scalp dry shampoo that leaves hair looking first-day fresh with clean, weightless body and the scalp feeling calm and comfortable. The Nº.4D Clean Volume Detox Dry Shampoo is clinically proven not to clog pores or leave a white, powdery residue.
