Makeup brushes are an investment piece in your makeup kit. Even if you only have 1 or 2 nice brushes, you should take care of them. Wash them at least once per month, preferably every other week with a gentle shampoo or soap. Some people like the Dr. Bronner’s Castille Soap (find it online, at your local natural food market, and most Target stores).
When storing your brushes, place them with the handles down, bristles upright to prevent fraying of the brush…
I keep all mine in a black plastic cup (here’s a hint- ReStore sells them for 25 cents to raise money for charity! They’re prefect for your little makeup samples, eyeshadows, and holding brushes!).
And my latest brush accessory? Brush protectors from Purely Cosmetics. They are similar to the old Chinese Finger Traps you played with as a child. Made of super stretchy plastic mesh, you slide them up the handle until you brush it covered. And when I say super stretchy, I mean it. The large will fit the biggest Kabuki brush you have!
The brush protectors are available at PurelyCosmetics.com. Prices are 50 cents for the small, 75 cents for medium size, and $1.25 for the large.
