For best results you want a beard oil with jojoba, argan and coconut oil. Scents aren't a problem as long as they are scented with essential oils not fragrance oils. The only beard oils worth getting are the ones containing only jojoba, argan and coconut oil and pure essential oils. There are a lot of people who think they know how to make beard oil now, but most of them have no idea what they are doing and they will use grapeseed or some other cheap oil that goes rancid quickly.
