Lol….I had one come off on my face today….newer Omega boar.Nope, not here.
I've never had a loose boar bristle on my face. I use Omega and Semogue mainly.
Sounds like you're judging all boars by your defective brush. Or do you have multiple lather-hogging shedders?
I'm sorry that you are experiencing this misery and anguish. Don't give up yet!
Sometimes I ask myself why I'm using a sub-$20 boar brush when I have all these lovely and expensive badgers.
It's because they work, putting nice lather on my face.
edit: Throw that wretched brush in the trash.
