Final answer:
In wig styling, all aspects must appear convincing except for the natural hairline.
Step-by-step explanation:
b. Realistic hair texture
In wig styling, all aspects are crucial for creating a convincing and natural look, so the statement "all of the following must appear convincing except" might be a bit misleading. However, if we interpret it as identifying the factor that is not directly related to the physical appearance of the wig, then the answer would be:
a. Understanding the effects of chemicals
While understanding the effects of chemicals is important for the maintenance and care of wigs, it may not be immediately visible in the wig's external appearance. Realistic hair texture, proper fitting, and a natural hairline are all fundamental aspects of achieving a convincing wig style.
b. Realistic hair texture is essential for making the wig blend seamlessly with natural hair. The texture should match the desired look, whether it's straight, wavy, or curly.
c. Proper fitting ensures that the wig sits securely and comfortably on the wearer's head, avoiding an unnatural or awkward appearance.
d. A natural hairline is crucial for disguising the boundary between the wig and the forehead, creating a more authentic and undetectable look.
In summary, while understanding the effects of chemicals is important for overall wig care, it may not directly impact the visible, convincing aspects of a well-styled wig.
