A deep conditioning treatment primarily serves to add moisture and improve hair elasticity. This treatment works by penetrating the hair shaft with nourishing ingredients, which helps to restore hydration to dry or damaged hair. When hair is well-moisturized, it becomes more elastic, reducing the likelihood of breakage and improving overall texture. This is particularly beneficial for individuals with coarse, curly, or chemically treated hair, as these hair types often require more moisture and care.

In contrast, while deep conditioning treatments can contribute to added shine and luster, this is not their primary purpose. Similarly, they do not specifically repair split ends; rather, addressing split ends typically requires trimming. Changing hair color is unrelated to the effects of deep conditioning, as this process typically involves chemical application rather than treatment meant for nourishment and moisture.
