This makeup brush shampoo is super handy. The shampoo allows you to give your brush a deeper cleaning since the shampoo is solid and embedded within the jar. I used to clean my brushes with baby shampoo - but found it left a heavier scent after the brush dried. I like that this brush shampoo has antibacterial properties and it doesn't leave your brush smelling soapy. It's so quick and convient compared to using liquid shampoos. All you need to do is rub your brushes onto the solid bar and rinse.
