Which blow-dryer works best for straightening hair?
The key to great-looking straight styles is drying the hair fast to reduce frizz. A high-wattage blow-dryer -- 1800 to 2700 watts -- works best. Start by dividing your hair into sections and use your dryer's nozzle attachment to direct the heat downward. A big round brush will provide the tension you need to smooth the hair as you dry and create the sleek look you desire. When purchasing a hair dryer, go with a professional model. They cost a bit more upfront, but they last a lot longer than the drugstore brands.
