A hair styling apparatus includes a hair-heating device for applying heat to hair. The hair-heating device has a moisture-temperature setting and a dry-temperature setting less than moisture-temperature setting. A moisture sensor detects a moisture-indicating parameter of the hair, and generates a moisture-indicating signal indicative of whether the hair is at or below a predetermined moisture threshold level. A control circuit adjusts the temperature of the hair-heating device from the moisture-temperature setting to the dry-temperature setting in response to the moisture sensor generating a moisture-indicating signal indicative of the hair being at or below the predetermined moisture threshold level. The hair-heating device is active in the dry-temperature setting.
