After about a decade of wet shaving and mostly using boar brushes and Whipped Dog brushes I finally got myself a Simpsons Brush. After much deliberation on price and knot size etc I went with the Commodore X3 in Best Badger due to the handle being bigger and the 24mm knot. My question is the instructions that came with it say not to use circular motions and only painting strokes. Fair enough, but will circular motions truly damage the hairs? With my other brushes especially when I shave my head (a much larger surface area then my face) I would always use circular motions to get the lather on and hydrate then I would finish with painting strokes. Would I still be okay doing this or is it best to just use painting strokes only?
