hair dryer with cool setting

Many models include a Cool Shot (or Cold Shot) button that delivers a burst of cold air to set and lock a finished style.

Most models list 1875 watts of output; a few styling tools list lower wattage—for example, one brush-style tool lists 1000 watts.

Product details list cord lengths ranging from about 5 to 6 feet, with examples shown at 5 ft, 5.5 ft, and 6 ft.

Some salon-style descriptions specify a professional AC motor and claim it delivers faster drying and longer motor life—for example, up to 50% faster drying and up to 3× longer motor life compared with DC motors.

Product descriptions consistently say the cool/cold shot button is used to set or ‘lock in’ a finished style, using phrases such as “lock in your look,” “set your look in place,” or “freeze your finished style.”
