The primary function of a hair straightening treatment is to smooth out curly or wavy hair for a straighter appearance. These treatments can vary in terms of their chemical processes and techniques, but the goal is generally to eliminate frizz and create a sleeker, straighter look. Hair straightening treatments often work by breaking and reforming the bonds in the hair structure, resulting in a more manageable style for individuals who desire a straightened effect.

In contrast, adding volume to flat hair pertains to styling techniques aimed at amplifying body, which is not the primary purpose of straightening treatments. Lightening hair color and permanently curling it involve entirely different chemical processes and outcomes, and thus do not align with the intended results of a straightening treatment. Overall, the focus of straightening is specifically to alter the texture and shape of the hair, leading to a straighter and sleeker appearance.
