Using this beard oil roller set is a breeze. First, roll the oil onto your beard and gently massage it into your skin and beard hairs. This helps the natural oils penetrate and do their magic. Do this once or twice a day, preferably after washing your face. As for precautions, keep the product away from your eyes. If you have any skin allergies, test a small amount on your skin first. To maintain the quality of the kit, store it in a cool, dry place. This way, you can enjoy a fuller, healthier beard for a long time.
