Can boar brushes be used with all shaving creams?

Yes, boar shaving brushes are versatile and can be used with any type of shaving cream or soap, making them a great addition to any shaving routine. 

Boar brushes are especially good at softening when soaked in warm water, making them ideal for use with thicker creams or hard soaps. However, they may feel stiffer than synthetic or badger brushes when new, but they soften over time with regular use, providing an excellent lathering experience.
