A good set of brushes can last you at least a couple of years. In order to keep them in good shape, treat them with extreme care and keep them clean. You do not have to wash your makeup brushes every time you use them but if you wear makeup every day, you should definitely wash them once a week.here is how to take care of your brushes
1. Gently wash them with a baby shampoo or a brush cleaner.
2. Once you are done, lay them flat on a piece of paper towel. Do not stand them up because the water will drip into the part connecting the handle with the metal part and this will mess up the glue inside.
3. Let them air dry. Do not attempt to make them dry faster by using a blow dryer. This will only damage your brushes.
4. Once they are completely dry, gently reshape them.
