The term 'infusion' in hair treatments primarily refers to the application of nutrients or moisture into the hair shaft. This process is designed to penetrate the hair cuticle, providing essential vitamins, minerals, and hydrating agents that can help restore health, enhance shine, and improve the overall appearance of the hair. Infusions are commonly used in conditioning treatments and masks, targeting dry or damaged hair to improve its texture and strength.

The other options touch on different aspects of hair care and styling but don't align with the specific definition of 'infusion.' Deep cleansing of the scalp focuses on removing product buildup and impurities but does not directly involve the application of nutrients into the hair itself. Color application refers to the process of adding pigments to the hair, which is distinct from infusing moisture or nutrients. Heat application for styling is related to the use of tools to shape and set hairstyles rather than the nourishing aspect that 'infusion' implies.
