I personally tend to swap between Herbal Essences and Pantene about every other bottle, so I am no stranger to Pantene products.
What I have noticed about this shampoo/ conditioner:
1) The conditioner is THICK, so you really want to keep from adding too much to your hair... it can take a long time to rinse all of it out (Yes I made this mistake)
2) The scent is nice, though nowhere near as potent or long lasting as the original Pantene products.
3) My hair did stay more "calm" although this could be because of the buildup that Pantene is known for.
4) I didn't find that my hair was any smoother to the touch then when using the Herbal Essenses or other Pantene. In fact it actually FELT a little rougher then after using the other Pantene products.
In conclusion - I'm not sure that I would spend extra money on this line of products, but I certainly didn't find anything wrong with them. I would have a hard time buying Pantene products and not having that smell that I so love. Still if this is your hair type and you have frizz issues, you might at least want to give this a try. It's no miracle but it can help a bit.
I can honestly say this is my favorite drugstore hair product line.
