Is it normal within the first week or so of using a brush to have it lose a few hairs? I've just finished my first week with a C&E (EJ) pure badger and while it seems to be softening up nicely and holding more water than it did at the outset, it's also lost about 4-5 hairs. Is this atypical? Does it taper off after the brush has been broken in fully? I don't think I'm being rough with it by any means and I can't think of anything else I could have done to it. Thoughts? Advice? Thanks.
