What is a really good shampoo for greasy hair?

Get a good clarifying shampoo, this breaks up the build up and dandruff in your hair. Ion from sally's beauty supply store is where I got this. Now, for a conditioner try to find silk products in it. And when you use your conditioner don't put it on the top your head since this makes your hair greasier anyway, rub it on your ends. Hope this helped. :)
