cleaning your brushes can be as simple as wiping them on a dry towel or napkin. in fact, i keep a small face towel on my bathroom counter for the purpose of wiping excess powder from my brushes between applications. about once a week i will take my brushes out and give them a good wash. (clients, have no fear, your brushes are washed between every use and i have a seperate kit just for you) here's what i do:
step 1: one at a time, rinse your brushes under warm water removing any loose excess dirt and makeup.
step 2: take a small drop of baby shampoo and apply to palm of your hand. gentle rub makeup brush in your palm to work up a lather. if the brush is especially dirty, like my face powder brush, i will rinse and repeat two or three times.
step 4: blot dry on a towel, form bristles to their original shape and lay flat to dry.
enjoy your clean brushes!
