High humidity affects styled hair primarily by causing frizz and a loss of style hold. When the air is humid, moisture is introduced into the hair shaft. Hair, being porous, tends to absorb this extra moisture, leading to a swelling effect that disrupts the hair cuticle's smoothness. As the cuticle lifts, the hair can humbly become frizzy and lose the definition of the style that was originally created.

Additionally, the moisture from high humidity often causes styles to relax or fall flat because the hair's natural texture can become more pronounced, overpowering any styling products used to maintain the shape. Consequently, achieving and maintaining a polished look becomes more challenging in humid conditions.

In contrast, the other options do not accurately reflect the impact that high humidity has on styled hair as it generally does not enhance styles or make hair more manageable. While some may perceive increased volume in certain styles under humidity, the predominant effect is frizz and loss of control, making it the most accurate choice.
