What does the term "infusion" refer to in hair treatments?

  1. The process of coloring hair

  2. The process of applying concentrated nutrients or oils to the hair

  3. A technique for cutting hair

  4. A method of straightening hair

The correct answer is: The process of applying concentrated nutrients or oils to the hair

The term "infusion" in hair treatments specifically refers to the process of applying concentrated nutrients or oils to the hair. This method is designed to deeply nourish and hydrate the hair, enhancing its overall health and appearance. Infusions often utilize ingredients that are rich in vitamins, antioxidants, and essential fatty acids, which help to repair damage, soften the texture, and provide moisture to dry or brittle hair. In contrast, the other choices pertain to different aspects of hair care and styling. Coloring hair involves altering the hair pigment, which is a separate process focused on aesthetics rather than nourishment. Cutting hair refers to the technique of shaping and trimming for style, unrelated to nutritional treatment. Straightening hair focuses on altering the hair's structure to achieve a smooth appearance, which is also distinct from the infusion process aimed at enhancing hair health. Understanding these distinctions can help in identifying effective treatments based on individual hair care needs.
