I have been breaking in a couple of new Semogues, the SOC and the 610. Both great, so far. I love the handles and the different lofts, each for its own reasons. But I notice both of them start to lose the lather in between passes. By the second pass, it's like the lather just dissipated. Is this because they're not yet fully broken in? Will they hold more lather the more I use them?
