the trick is only use a small amount. My hair is shoulder length and I use about the size of a nickle on my wet hair. I put it in my palm and rub my hands together and stroke it down through the bottom half of my hair. It makes it soft AND adds volume.
I mixed my co with some shea butter maybe that's why it gives it more body. Yup, I found out the hard way if I use too much it just looks dirty and greasy.
