Ok just so we're clear, this review is referring to every single kind of Pantene Shampoo - classic care, straight & sleek, nature fusion, you name it. I've tried them all, and I find their performance extraordinary. I know absolutely nothing about hair. I never use styling products, and half the year I don't even use a hairdryer. So this comes from an absolute hair rookie: I love it. I've been using it for ten years straight and I haven't found another brand that holds a candle to this one. It's amazing. I wash my hair in the shower, and when it dries it's left incredibly light, glossy and sleek. I have naturally straight, heavy hair with very little volume. This shampoo leaves it so clean it just flows in the wind, almost weight-less and quite voluminous, for about an entire day. After that I don't need to wash it for another 3-4 days: On the first day my hair is commercial-clean, on the second day it looks great, on the third day it looks very decent, and on the fourth day it starts to look not so fresh, so right there or on the fifth day tops, I'll wash it. This might sound like too rare of a wash comparing to most people, but I seriously want to squeak in terror when I hear especially women say they wash their hair every day or every other day. I imagine if I did that, there wouldn't be a single hair left on my head by now. Plus why do it, if it looks so good and fresh for 3 days in a row. Aaanyhow, my favorite scent is the Nature Fusion one. It's divine, makes me want to eat the whole thing. Have been and will be repurchasing!
