I don't buy expensive shampoos, but a trick you can try if you want your hair to look nice is having at least 3 different kinds of shampoo in the shower and using a different one each day. "Cheaper" shampoos leave a build up on your hair, so if you switch every day you are cleaning away the buildup. I have Fructis, Salon Selectives, St. Ives, Dove and the walmart brand of Herbal Essence and I use a different one every day, and it really does work!

I bet your hair smells really nice though, with this new product!
