If you are trying to decide whether you want to invest in a dry brush cleaner, Color Switch, or purchase a hair donut instead, I am here to help. Whether your brush collection is small or you have some brushes you love that you use for multiple colors, a dry brush cleaner can help. It is mostly commonly called a color switch, because the most popular one from Sephora and Vera Mona includes that in the title. Just like some will ask for a Kleenex when they want a tissue, some will ask for a color switch when they want a dry brush cleaner. They are also really helpful for people who swatch products using brushes. Let me know below if you want my reasoning for why brush swatching is usually wasteful and unnecessary. A color switch removes powder products from your brushes without any liquid. Yes, you can use a dry brush cleaner on cream products, but it will not remove as much product and will have you washing your dry brush cleaner more often.
