Why do I need to put oil on my beard? It grows just fine. Our beard oil will not help your beard grow. If I was able to make a tonic that made hair grow, I would use it on my own head first. What our Beard oils do is soften the beard, help relieve dry itching beards and make it smell amazing. Our beard oil is available in all of our rugged man scents from clean to woodsy and from fruity to straight up dirt.
