Final answer:
Kanekalon is popular for hair extensions due to its heat sensitivity, allowing it to be styled with high temperatures, making it a cost-effective and durable choice.
Step-by-step explanation:
The answer to the question about the attribute of kanekalon that makes it extremely popular for use in hair additions and extensions is its heat sensitivity. Kanekalon is a type of synthetic fiber that is favored for its ability to withstand high temperatures which allows for versatile styling options such as curling or straightening. Unlike natural human hair, it has the advantage of being more durable and maintaining its style longer, which makes it a cost-effective and convenient choice for hair extensions and wigs.
Kanekalon's heat sensitivity is one of the reasons it is popular for use in hair additions and extensions. This synthetic fiber has a low melting point, which allows it to be easily styled with heat without damaging the fiber or causing discomfort to the person wearing it. For example, kanekalon can be curled or straightened using a flat iron or curling iron. This versatility makes it a popular choice among those who want to change their hairstyle.
