For me, this product is better than it is worse, but it still has a couple of distinctive flaws. For one, I HATE the nozzle. It sprays a direct, narrow stream instead of a mist which causes even distribution really hard to get. I still have the bottle from the old Pantene Pro-V Heat Protectant which had a really good nozzle, so I just switched them, but it would probably be a hassle for people who didn't have it.
Secondly, again, unlike the old Pantene Pro-V protectant, this new one has a formula that sort of makes it sticky, before I use heat and even sometimes after. Further more I like the smell of the product and it leaves my hair quite soft afterwards...
