This is marketed as a "Boar Bristle Brush", but in reality, it is a hybrid brush mainly consisting of stiff nylon bristles with just a few boar hairs mixed in.
It's a bit like selling a "dark chocolate" that is actually pure palm oil with 4% cocoa.
If you're looking for a pure natural hairbrush without plastic/nylon, you'll be disappointed here. It was cheap, and I'll probably use it for my hair, so I'll keep it. But I strongly deduct stars because of the misleading naming from the store. Others should know what they are actually buying.
This is not a 'boar bristle brush'. This is a nylon bristle brush with a few boar hairs.
