In our professional dry body brush range, we use the finest Mexican Tampico for the bristle fill which is preferred by therapists and experienced body brushers for dry body brushing treatments. Cactus is the firmest type of bristle available and is the most effective. If you are new to body brushing try light strokes first and build up to harder strokes as the skin gets more used to it. For very sensitive skins it may be preferable to start with a softer natural bristle brush and work up towards the coarser cactus.
