Linen oil is used to clean guns. I use it for my blades and for my face and hairs (though they aren't weapons). Indeed, it is very good and suggested to repair skin (5 drops for the full face, after using soap) and soften/repair long hairs (10 drops after washing). You should try!! It's fantastic!!! Also, it should be produced with "cold" methods, to preserve its properties, so pay attention when buying. I pay it 6$ per 100 ml.
