Vegan alternative Boar Bristle Brush?

Hi all!
I have recently started my No Poo journey and have been looking up a lot about it. The oil distribution in my hair is very uneven and I heard that the Boar Bristle Brush can do wonders. Also the scritching and preening is suppose to help, so I will definitely check that out. But now I was wondering; since I am vegan, is there a vegan option for the BBB brush (that is available in europe)? I found the Kostkamm brushes online, but I dont know if they are any good and if they will do the trick.
Would love to hear your experiences!
