Beard brushes are good on many beard levels; especially for those who have short, tighter beards to the face.
 
A good comb will help train your beard by brushing it in the direction you want it to lay. Also, while combing through your beard, they will pull the oil evenly though your beard, and will also help your hair follicles by increasing a healthy blood flow.
 
Texas Tickler Beard Co offers both soft and firm bristle brushes, while they offer subtle differences, ultimately, the type of brush needed depends on the person. The firm bristles tend to comb through thicker, more course hair more easily and thoroughly than the soft bristles. The soft bristles tends to massage the face more gently and scratch your face less.
