Amazing on wet hair, works like a comb but so much better... I love using this on my kid's wet hair, much faster and much less painful then using a comb. If your hair is dry, you have to wet the brush or it will get stuck. You will love this if you have kids, great for adults too!
Then go to Beauty.com and get Rene Furterer's, "Fiorvanit" Dull Hair Extreme Shine in the green spritz bottle. Pricey but amazing stuff for quickly getting out tangles and making hair gorgeous, love, love, love it! My girl's long hair no longer looks stringy but beautiful!
