What technique involves combing small sections of hair from the ends toward the scalp to create a cushion?

The technique known as teasing involves taking small sections of hair and combing them from the ends towards the scalp. This action creates a cushion of hair, which adds volume and texture. Teasing is particularly useful for styles that require lift at the roots, as it creates a "backcombed" effect that can support various hairstyles. When done correctly, it can give hair a fuller appearance without the need for additional products.

In contrast, slicing refers to cutting techniques that create texture without removing bulk and is not focused on manipulating hair for volume. Backbrushing is similar to teasing, but it typically involves brushing in a direction toward the scalp rather than combing, often used to blend and smooth styles rather than to initially create volume. Smoothing, on the other hand, is aimed at eliminating frizz and creating a sleek look, which does not involve the specific backcombing action that characterizes teasing. Thus, the definition of teasing aligns perfectly with the described technique, making it the correct choice.
