There are many differences in shaving brushes and, quite honestly, it’s difficult to pinpoint the “very best” because it ultimately comes down to personal preference. But generally speaking (without going into too much detail), badger hair brushes are considered the best and most recommended by industry standards for their long history, natural bristle softness, durability, and water retaining qualities.
Within the badger hair category of brushes, you’ll find different grades of hair. These grades denote quality. Higher-ranked hair grades are typically softer and feel more pleasing on the face. Additionally, while all brushes need to be soaked, the best, higher-grade shaving brushes require a much shorter soaking time, as they are much better at holding on to water and lather.
The most recognized grades of badger hair (from highest to lowest quality) include Silvertip, Super, Best, and finally Pure.
Outside of badger hair brushes, there have been many advancements with synthetic brushes in recent years and you may find these to be suitable for your routine.
