Beard oil is used to moisturize and soften your facial hair. It also effectively moisturises the skin beneath your beard. People have been using beard oil or naturally available oils such as jojoba oil, cedar oil, peppermint oil, avocado oil, coconut oil, etc. to keep their beards healthy and softer, while also giving them a fuller appearance. It promotes beard growth, but the amount of growth, if any, will ultimately depend on the individual’s genetics.
