What technique involves using a comb to create a cushion at the base of the scalp for added height and volume?

The technique involving the use of a comb to create a cushion at the base of the scalp for added height and volume is back-combing. This method is widely utilized in hairstyling to achieve a fuller look, especially in updos or styles that require significant volume at the roots.

During back-combing, the stylist takes small sections of hair and pushes them towards the scalp using a comb. This action interlocks the hair strands, creating a base of tangles which results in the desired height and provides a strong foundation for the hairstyle. The hair can then be lightly smoothed over the top to create a polished appearance while maintaining the underlying volume.

While back-brushing and teasing are sometimes used interchangeably in casual conversation, back-combing specifically refers to the technique of combing the hair back towards the scalp, making it distinct in the context of creating bulk at the base. Braid padding and other options listed do not focus specifically on puffing up the roots in the same way that back-combing does, and they typically involve different styling methods altogether.
