The most important thing is that you need synthetic fibers for applying wet makeup such as concealed, liquid foundation liquid eye liner and lip stick and natural fibers for applying powder such as blush, eye shadow bronzed etc. To care for your natural fibre brushes soak them in baby shampoo- they are hair so need a nice gentle shampoo and lay them out flat to dry. If you take care of them they will last and give you good results.
