You may even be able to purchase tools designed to remove hair from your brush. Alternatively, you can also try using a hair pik or the end of a rat tail comb.
If you have a brush with a wooden handle, avoid getting the sides wet, however. Water can damage wood.
Let the brush or comb air dry after cleaning it. If you’re in a hurry, you can also pat it dry with a paper towel or rag or use a hair dryer on medium heat a few inches away from it.
It may be best to avoid harsh cleaners, like rubbing alcohol, on wooden brushes.
