dry oils; think Jojoba, Argan, Coconut. I’m currently testing beard oils to find the best so i can bring it TDB followers.
if you’re buying a specialty beard oil check the ingredients make sure there’s no silicone in it. usually you can spot them in the ingredients as anything ending in ‘cone.’ you don’t want them because they’re used to stretch oils and they counter the benefits of oils by creating a layer around the hair so the oil can’t get in.
