Since discovering Olaplex No. 3, I have tried every product that they have ever released so it goes without saying that I bought their recently released No. 4D Clean Volume Detox Dry Shampoo. I wash my hair once weekly so dry shampoo is an essential part of my hair product collection. This one offers a lot in the name but it's also pretty pricey and I have two that I adore so it really did have stiff competition, but I just couldn't not try it!
