Which of the following is a primary benefit of using synthetic hair in hairstyling?

Utilizing synthetic hair in hairstyling offers several key advantages, and one notable benefit is its ability to remain unaffected by humidity. This characteristic makes synthetic hair an excellent choice for individuals living in humid climates or for styles that require prolonged wear. Unlike natural hair, which can absorb moisture from the air, leading to frizz or changes in texture, synthetic fibers are crafted to maintain their intended shape and style, regardless of the surrounding environmental conditions. This reliability means that hairstyles created with synthetic hair can maintain their polished appearance throughout the day, even in challenging weather.

In contrast, other options, such as being easily colored, withstanding extreme heat, and allowing for customization, do not accurately reflect the primary benefits associated with synthetic hair. For example, synthetic hair is not designed to endure high temperatures effectively, as heat can cause damage or alter its structure. Additionally, while some synthetic materials can be colored, they generally do not take dye as well as natural hair does, leading to limited options for customization. Therefore, the exceptional resilience of synthetic hair against humidity is what primarily sets it apart in hairstyling applications.
