Makeup brushes can be made of natural or synthetic materials. Natural makeup brushes are often made from animal hair such as squirrel, goat, sable, mink, horse, or badger hair
. Synthetic brushes, on the other hand, are usually made from nylon, taklon, or other synthetic fibers
. Some makeup brush sets are vegan and made of synthetic fibers
. The ingredients used in makeup brushes vary depending on the brand and type of brush. For example, some brushes use non-animal derived semisolid lanolin substitutes, while others use tallow from grass-fed cows, organic cold-pressed olive oil, and certified organic essential oils
. Dome Beauty's brush kit includes brushes infused with charcoal to prevent the buildup of harmful bacteria, and a cleaning pad with three different cleaning surfaces for varying products
