Olive oil promotes a moisturized and healthy scalp, fights infections caused due to bacteria and improves the blood circulation in your scalp. A better scalp blood circulation makes your hair follicles stronger thereby helping to produce hair strands that are softer, healthy and thicker. Make sure not to use too much Olive oil, as it has some pore-clogging potential. It's naturally high in squalene, an oil that mimics your skin's natural sebum, so it'll leave your skin barrier extra smooth and soft, and it's also full of antioxidants that work to fight environmental skin damage. Comes in 8 and 4 ounce bottles.
