Hairgurt Smoothing Yogurt Shampoo is Sulfate Free and Paraben Free and loaded with healthy hair ingredients. We, the beauty junkies at Hairgurt, have created a balanced blend of six botanical oils to feed and nourish your dry, damaged hair. Let’s take a deeper look at our oils, and you’ll see why we chose them. Hazel Seed Oil, extracted from hazelnuts, is high in Vitamin E and essential fatty acids. Its fine texture, allows it to be absorbed quickly and penetrate deeply into dry hair. Sweet Almond Oil’s beneficial properties include high amounts of Vitamin E and fatty acids. It naturally holds moisture in for longer periods of time and helps add shine to dull, dry hair. Macadamia Seed Oil’s omega-6 and omega-3 fatty acids coat the hair shaft and help improve strength and elasticity of hair.
