What is the primary purpose of using a blow dryer in hair styling?

The primary purpose of using a blow dryer in hair styling is to dry hair and set the style. When hair is freshly washed, it is typically damp, and before any styling can effectively be done, it must be dried to allow products to adhere properly and to achieve the desired shape and texture. The warm air from the blow dryer not only evaporates the moisture but also enhances the styling process, enabling various techniques such as curling, straightening, or volumizing to be executed more effectively.

Additionally, blow drying can help activate styling products applied to the hair, ensuring that they work optimally to hold the desired look. This versatility makes the blow dryer an essential tool in the styling toolkit, as it prepares the hair for further manipulation.
