Am I somehow killing my brush faster than normal?

[Ragnorok64]

So I have a Winsor Newton Series 7 #2 brush. I really like it but it seems every time I use it there's new hairs on the brush going in some sort of funky direction. Everytime I use it I make sure to wash it out with "The Masters" brush clearer and I leave a little bit on the brush, reform the tip, then put the plastic protector on it. When I wet it I can still get it to point but it seems to be getting wonkier and wonkier. I don't even ink that often. Is there something essential that I'm not doing or doing incorrectly here? Is it just a case of a bad brush to begin with?

Edit: I've been using Dr. Ph Martin's Bombay black india ink and, my current favorite, Pelikan tusche A drawing ink.
