I've been thinking of getting a hot brush but am worried it might be too damaging. I have thin, fairly fragile hair which I wash two or three times a week and blow dry. It's in a collarbone length blunt bob. If you have the one step does it pull out much hair and how cool is the lowest setting? Not sure how it compares with babyliss big hair or flawless volume in terms of how damaging it might be. Reviews are so mixed . TIA
