I use a pure badger brush and have been using Baume.BE shaving cream and the problem I have is that when I go to apply the lather on my face, all the lather just goes on to the back and sides of the brush and not on the part of the brush that I put on my face and it doesn't go on very well. Maybe I just need a better brush? I ordered a Parker Synthetic off amazon the other day so I will be giving that a try as soon as it gets in. The other thing that is odd is that it seems like my Baume.BE doesn't lather as well as it used to when I first bought it either.
Try what I call THE CHIN ROLL. Hold the brush horizontally, place the base of the knot against your chin and roll the brush. Should squeeze out a bunch o' lather.
Are you face lathering or using a bowl? Face lathering will cause the brush to hog a bit if you don't paint some lather on. For bowl lathering I create a good lather then swish the sides of the brush on the sides of the bowl to squeeze the lather toward the tips.
I am bowl lathering. It occurred to me though, I think the problem is worse when I let the brush soak, pre-shaving, then when I don't.
The water higher up in the knot is helping create lather. Give your brush a good shake to get the water down before creating lather. Some brushes are lather hogs. They just seem to like keeping all the lather close to the handle. Squeezing the lather towards the tips or painting instead if swirling helps.
