Promising review: "I have fine, delicate, naturally curly hair, which I usually blow out straight. Every now and then, on a rainy or humid day, I do like to leave it natural. It never looks good, because the curl is not strong and if I don't handle it just right, I'll be left with a frizzy, shapeless mess. This unique, one-of-kind diffuser is the answer. It doesn't burn or damage my fragile tresses. It delivers great volume and keeps my curls in tact while keeping the frizz-factor to a minimum. My hair still looked good the next day, too, which almost never happens with fine hair. Worth every penny!" —T.L Scarito
