What does the term "frizz control" refer to?

The term "frizz control" specifically refers to products and techniques designed to minimize flyaways and manage hair texture issues. When hair is frizzy, it generally appears dry, uncontrollable, and has a rough texture that can make styling difficult. Frizz control products often contain moisturizers, smoothing agents, and silicones that help to seal the hair cuticle, thus reducing the appearance of frizz and providing a sleeker, more polished look. Using such products can enhance the overall health and manageability of the hair, allowing for more effective styling and a more desirable finish.

The other choices do not accurately capture the essence of frizz control: straightening hair is a specific technique that may help reduce frizz temporarily, but it is not the same as frizz control; adding volume to hair focuses on creating lift, which can sometimes exacerbate frizz; lastly, styling techniques for curls aim to define and shape the curls themselves rather than addressing frizz specifically. Therefore, the correct understanding of frizz control centers around managing frizzy texture and improving the overall appearance of hair.
