Which technique uses a brush on the surface of the hair to create a light and airy appearance?

The technique that utilizes a brush on the surface of the hair to create a light and airy appearance is back-brushing. This method involves using a bristle brush to gently tousle the upper layer of hair away from the scalp, creating volume and movement while maintaining a soft finish. This technique is particularly effective because it does not disturb the base structure of the hair, allowing for a more natural looking lift.

Back-brushing is often performed after styling to enhance the look without making the hair feel heavy or weighed down. It serves to blend the hairstyle, adding texture and giving the hair a finished, attractive shape that appears fuller and more dynamic.

In contrast, back-combing is a technique that creates volume and structure by teasing the hair at the roots, which can often lead to a more defined and polished look but may not achieve the light, airy appearance desired in this context. Pin curling is a method used to create curls and waves in hair but does not focus on achieving an airy texture. Hair spraying, while essential for setting styles and adding hold, is not a technique that directly manipulates the hair in a way that creates volume through brushing alone.
