I've not used either of these products, hopefully someone who has will come along with their comments.

As for the Pantene, these products are heavy with silicone derivatives (look for ingredients ending in -cone).  Cones can build up on your hair.  Initially they will make your hair feel smooth and silky, but with time, if the build up is not removed, the hair can no longer absorb any moisture and it will become brittle and prone to breakage.  This can be prevented by removing the build up regularly with a clarifying shampoo or doing a vinegar/water rinse between your shampoo and conditioner.

Everyone's hair is different and will react differently to hair products.  What works for one person will be horrible for another.  You have to find what works best for your own hair (not an easy task!).

I love Suave Citrus and Ginsing, Suave Coconut, VO5 Kiwi-Lime Squeeze, White Rain Extra Body and the Citrus one.  All of these are conditioners that I do a Condition only wash and they all seem to get my hair very clean.  I only use shampoo once a week and before a deep treatment. 

White Rain is also on sale in many stores this week for a $1/each bottle.
You cant go wrong with that price.  So guess who bought some??
