'Duck Dynasty's' Si Robertson doesn't wash beard, says Willie Robertson

Been wondering how to get a beard as intense as "Duck Dynasty's" Si Robertson? Apparently the keys to that lookare to not obey the basic rules of cleanliness and let is grow uninhibited.

"Si's beard is really awkward," Willie Robertson tells Us Weekly. "One side is longer than the other, and it's about three different colors. I don't think he washes it. It's nasty."

But not all members of the "Dynasty" are so haphazard with their beard care. Jep Robertson has been known to shampoo, condition and then blow-dry his flowing beard, and that's only the beginning of his beauty regimen.

"Jep grooms his the most: He's got all these special lotions and perfumes that he puts on," Willie dishes.

But while Willie says his dad Phil Robertson has the "classic, mature beard" and Jase's reddish facial hair is "weird, like him," it's his beard that's said to be the best of the family.

"Willie was clean-shaven and actually a bit preppy when we got married," Willie's wife Korie Robertson says. "Now I absolutely love his beard and don't want him to go back!"
