Why Brush Bristles Matter

The Different Types of Bristles
 
Natural Haired Bristles
Usually sourced from animal hair, these bristles work well with powders. However, they can be a bit more difficult to take care of.
 
Dual Fiber Bristles
Give a lighter application because the top of the brush isn’t as dense.
 
Synthetic Bristles
Tend to be firmer, which Natalie Gee of Gee Beauty says works well for the texture of foundations and concealers. When used with powders they can cause a lot of fall out.
