Perming is the technique that specifically involves applying heat to the hair to achieve a waved or curled appearance. This process uses chemical solutions along with heat to break and reform the bonds in the hair structure, allowing for long-lasting curls or waves. The addition of heat enhances the effectiveness of the chemical solutions used in perming, ensuring that the desired shape is maintained.

While other treatments like deep conditioning can involve heat, they do so primarily to help open the hair cuticle for better absorption of moisturizing products rather than changing the hair's shape. Haircutting simply involves trimming the hair and does not require heat. Hair coloring, while it can involve some warming techniques in certain applications (like activating the color), is not primarily a heat application treatment like perming. Thus, perming stands out as the technique most closely associated with direct heat application to alter the hair’s texture.
