So far, I love the Pureology Colour Fanatic Mask. You don't need to use much product and it left my hair moisturized and soft. I've only used it once though so we'll see if it continues to perform well. I don't have colored hair so I can't comment on how it works with color.
Nature's Gate Biotin Conditioner has a nice herbal-mint scent, but it seems to take a lot to detangle my hair, and doesn't leave it particularly moisturized. I like the Pureology mask better - less work for better results.
