Pureology Hydrate System Duo Review

I have tried the whole line of Pureology products, and they are all wonderful!  The straightening products make my curly hair straight and shiny, the hydrating products condition like no other, and the volumizing products are a miracle for my fine, thin hair.  I like to mix the straightening shampoo with the hydrating conditioner, then apply the volumizer and the Root Lift before drying.  I end up with a new head of straight, shiny, full hair! I only wish the products were a little bit cheaper--I usually end up spending about $80 for the shampoo, conditioner, and volumizer.
