A common question we get at shows is “how long does a shaving brush last?”
As with most things in life, it varies. If you take care of a badger brush, it can last for many years. Perhaps the most overlooked and simplest way to ensure that your brush stays healthy is to thoroughly wash off the soap and let it hang dry after use. After you gently squeeze out the water, a couple shakes will suffice.
If you want to wash the brush then shampoo works fine, but don’t use harsh solvents or products like kitchen cleaners.
Another important tip to making sure your brush lasts is to avoid aggressively squishing the brush into your face when lathering. It is both unnecessary as well as likely to break down the hairs.
