The Scotch Porter Smoothing Beard Serum mixes the finest Avocado and Jojoba Seed Oils, leaving your beard moisturized, shiny and frizz-free. Unlike most beard oils that just sit on top of the beard and give the illusion of hydration, our beard serum provides intense, all day smoothing and shine to lock down hair cuticles and seal in moisture. Gender: unisex.
