Beard balms are designed for the wiry hair on the chin. Beard hair is dead keratin, and does not typically absorb nutrients. When the hair is there, the real aim of a beard balm is to condition that hair, and offer some light style for the potentially wild hairs.
Balms do not tend to shine and offer invisible support for a beard and condition throughout the day. The scent of balms are lighter than beard oils, as men wear the balm right beneath their nose for the entire day.
