Simplicity is key when it comes to Primally Pure’s Natural Dry Shampoo. When you shop for a dry shampoo, you’ll find several types to choose from, including sprays, aerosols, and powders. Primally Pure went with powder to create a hair care product that was simple and effective. But the simplicity doesn’t end there. The simplicity extends to just about every aspect of Primally Pure’s all natural dry shampoo.
