Wet hair is pliable and can be formed into new shapes with the use of heat styling tools. When the hair is dried with heat, moisture is removed, allowing internal bonds - dissolved when hair is wet - to re-form, resulting in a temporary set. This volume effect will be lost when the hair is washed and will also be diminshed by environmental factors, such as wind and sunlight.

Volume-Enhancing Blow Dryer Tips

The nozzle on a blow-dryer is useful in creating volume as it directs the heat exactly where it is required, at the root. Blow-drying hair without the nozzle often means the hair dries too quickly and the root hasn't had its fair share of the heat so that it can take on the shape one desires.

Heat is what molds the hair into new shapes. It is critical to use a blow-dryer if one wants volume. Blow-drying slowly, using a low-medium heat is best as it gives the hair more time to mold.
