A fibrous bristle load holds significant amounts of water which mix with the soap lifted from a shaving mug or scuttle. The more water a brush holds, the moister and richer a lather will be. Thicker and more emollient lather translates to less razor skipping and dragging. Bringing a shave brush across one's skin produces a mild exfoliation. Because a shave brush is most often used with a shave soap, this effect often replaces the pre-shave routine of washing and applying lotion to the face.
