The Warren-Tricomi Tension Brush is a great brush to use for blow drying or flat ironing hair. I place a small section of hair and glide the brush down it while I flat iron my hair. It helps get my hair really straight, and I have really thick, natural hair. My hair is short, so this brush can be used on short hair as well. Be sure your hair is in good enough condition when using this brush, because it does pull the hair, so I don't use it every time I need to flat iron, only when I need my hair really straight for an event.
