Lather: Enough lather for me - I'm used to sulfate-free shampoos that don't lather a lot.
Rinsing out: The shampoo and conditioner both rinse out easily, and my hair feels thicker in the shower--there is a bit of a 'squeaky clean' feel, and that helps with baby fine hair.
Look of hair: Very full and my hair even has some body, which it rarely does. Lots of shine.
Feel of hair: soft but not too slippery (baby fine hair can be too slippery sometimes and fall flat). It feels as if I've been to the salon.
Very happy with my order.
