Beauty Quickie: Sometimes makeup brushes can take a beating causing fibers to fall out or be damaged by harsh detergents. Prevent this by using a gentle shampoo in order to can clean brushes and keep them in shape as well as ready for use. Either lather up the brushes with the shampoo or allow them to soak in a cup. Add a small amount of baby shampoo to water then swish your brushes around and allow them to sit in the cup. After a bit rinse the makeup brushes and gently dry them.
