Lyrt said:Question: do brushes behave differently with soaps and creams? In concrete terms, is it possible for a brush to create a good lather with creams but not with soaps and vice versa?
To a lesser extent, yes. A decent brush will create lather with either and get it on your face. However, there are differences in brush styles and quality which affect how easy it is to generate that lather. Typically, a soap brush is viewed as one with shorter, denser, stiffer, hairs that can more easily remove soap from the cake. A cream brush, while not having to physically remove soap, tend to have longer and softer hairs. With both, the tips of the hair can range from scritchy/scratchy/scrubby to very soft. Additionally, there are most deffinetely general purpose brushes that can do both well.
