I have a Semogue 1305 boar brush which is only about 8 months old. Until a month ago, it was my favourite brush, it lathered great, it had great backbone (scritchy but not too scritchy), and it felt great against my face. But then suddenly it stopped holding lather. I've cleaned it a couple of times since then, but nothing has changed.

It will still build a lather nicely, but the lather will disappear very quickly from the brush after the first application. If I'm bowl lathering, the brush and lather will be all wet, but if I'm face lathering, the brush will be all dry.

Does anyone have any ideas as to what's happening? My other brushes are still great, sometimes I think they're getting better. But this Semogue is a real problem.

Thanks!
