I’ve found that my girlfriend’s clarifying shampoo is great for restoring brushes. Clarifying shampoo is for removing shampoo/conditioner residue from hair. I follow that up with a 1 minute soak in 50/50 white vinegar solution.
I have a hair brained theory, that dying brushes bristles up, causes them the wick back from the knot and that includes any yucky stuff that’s built up in there.
