How I clean my makeup brushes

Quite simply, it's just:

The theory is that the bristles on the brushes are made of hair, and what does one use to clean hair? Shampoo!

The shampoo is $3.50 for 32 oz from any drugstore or supermarket. One bottle can last my hair for 1/2 year. And that includes shampoo for cleaning my brushes too. That's pretty good!

Not bad huh?
