My dad has very fine hair, and has complained for years about being unable to find a shampoo that works with it. Years ago, he used one that had lanolin in it and it did wonders, but he could never find it again. I ordered the Wool Fat shampoo to see if would equal the one he loved, and it did! He's on his second bottle, and I don't think he'll use anything else as long as this is available! He says it's the only shampoo that gives his hair any weight and controls the natural curl. He really loves it. Big win.
