Even if you wash your brush thoroughly after each shave, a thin film of soap and lime forms on the brush hair over time. That stiffens the bristles and in the worst case, could cause them to break off the next time you shave. To prevent this, you should:
- Wash your brush at regular intervals with shampoo or detergent.
- Work with warm water.
- Be careful not to bend the hair when shampooing.
With these steps, you protect the hair structure of the bristles, maintain their flexibility, and extend the life of your shaving brush.
