What is the function of the blow dryer in styling hair?

The blow dryer is specifically designed to dry and style hair using heated air, making it a crucial tool in hair styling routines. When the heated air is directed onto wet hair, it not only removes moisture but can also assist in shaping the hair into the desired style. The heat helps to break down the hydrogen bonds within the hair, allowing it to be manipulated and styled with brushes or fingers effectively. This dual functionality—drying and styling—makes the blow dryer an essential device for achieving various hair looks. The use of heated air also allows for better control over volume and smoothness, which contributes significantly to the overall styling process.
