Hair Dryer vs. Hair Iron: What's the Difference?
Edited by Aimie Carlson || By Harlon Moss || Published on January 19, 2024
Hair Dryer is a device that blows hot or cold air to dry hair. Hair Iron is a tool used to change the structure of the hair using heat.
Key Differences
A hair dryer, also known as a blow dryer, is used primarily to dry wet hair through hot or cold air. In contrast, a hair iron, including flat irons and curling irons, is used to style hair by applying heat directly to change its shape or texture.
Hair dryers are equipped with a fan to blow air, which can be heated, over wet hair to accelerate the evaporation of water. Hair irons, however, apply heat through their heated plates or barrels to alter the hair's form, either straightening or curling it.
Hair dryers can also assist in basic styling with the use of attachments like diffusers, while hair irons offer more precision in styling, enabling the creation of specific looks like pin-straight hair or curls.
Hair dryers are generally safer for regular use as they do not come in direct contact with the hair, reducing the risk of heat damage. Hair irons, requiring direct contact, can lead to hair damage if used excessively or without proper heat protection.
Hair dryers are versatile in terms of temperature and speed settings, catering to different hair types and drying needs. Hair irons usually have adjustable heat settings, allowing for control over the intensity of styling based on hair texture and type.
