7 DAYS Beard serum products are a blend of various ingredients, such as jojoba oil, argon oil, coconut oil, grape seed oil, and hempseed oil that are used to address specific beard problems such as itching, sensitive skin or dryness by going straight to the follicle in a similar fashion to hair conditioner. Beard oil acts as a moisturizer that goes straight to the hair follicle and restricts hair from growing brittle, especially in cold, windy environments as these weather conditions cause the natural moisture of the beard area to wick.
