One of the biggest mistakes that most men make when it comes to washing and styling their hair is using too much hair product. Pete & Pedro never wants you to waste your money and product! Aaron shows how much shampoo you need which is typically a nickel/quarter size of Clean – our fan-favorite daily shampoo. The reason is that high quality shampoos tend to be concentrated so you don’t need much as a little goes a long way. So, always say less is more when cleaning up these days! You can always add more if you need too, but start small.
