It made a huge difference for me. The brushes aren't as stiff afterwards and much softer...a lot like hair I suppose. Makes them easier to reshape as well. I leave it on for a couple of minutes, not too long. Usually just long enough to wash the gungy water I've been washing the brushes in out of the basin!
