I have been watching a lot of shaving videos. I see that some people like to use circular motions. That technique seems to work well with a less dense brush, as the brush bristles splay to allow the lathering. Do people with dense brushes use circular motions as well? I find that the dense brushes work well at getting the product loaded. However, I find that painting strokes seem to work better than circular motions. If I use circular motions, I feel like I am just wearing down the tips. What are your thoughts on this?
