Why should I use Beard Wash instead of regular shampoo? (I like the beard guy and all…just wondering)

What’s the purpose of a beard oil? I know what oil does for my engine but how can it help my beard?

What’s the difference been your beard oils and Beard Quencher? I’m intrigued by Beard Quencher since I’ve not seen too many products like this in the market.

Why should I use Beard Control versus your beard oils? Can I use just one or do you recommend I use both?
