One of the first times my sister-in-law — makeup artist, entrepreneur, extraordinaire, Rebecca Perkins of Rouge New York — did my makeup using my own brushes she was horrified by how dirty they were. I had never washed them. Honestly, I didn't know I was supposed to wash them and even if maybe deep down I knew this instinctively, I figured it must be a chore. I had no idea how easy it was but it is. It's 6 steps.
Water.
Baby shampoo.
Lather.
Rinse.
Squeeze out water.
Lay flat to dry.
The only flourish Rebecca adds is that you can use conditioner for extra love. I am now much better about cleaning my brushes (every now and then) and use the soap in my bathroom when baby shampoo isn't on hand. I figured it's better than nothing. Life should be easy.
