Extensions refer specifically to artificial hair that is added to a person's natural hair to increase its length and volume. This technique allows individuals to achieve a desired hairstyle without waiting for their natural hair to grow out. Extensions can be made from synthetic materials or real hair and come in various styles, colors, and lengths, allowing for significant versatility in hair design.

Other options mention different aspects of hair care or styling but do not pertain directly to the definition of extensions. For example, products to enhance hair shine focus on improving the appearance of hair rather than adding length or volume. Hair products used before styling may involve sprays, gels, or conditioners that prepare the hair for styling rather than altering its length. Similarly, a technique for hair straightening offers a method of altering hair texture but does not relate to the concept of extensions. Thus, the focus of extensions is specifically about enhancing the overall length and volume of hair, making it a unique service in the realm of hair styling.
