The term that accurately describes the interlacing or tying together of one or two strands is known as a knot. In hairstyling, a knot is formed when strands of hair are intertwined and secured together, creating a stable structure. This technique is often used in various hairstyles to secure hair in place or to create decorative features. Knots can vary in complexity and style, ranging from simple loops to more intricate designs, but the fundamental aspect remains the same: the intertwining of hair strands to achieve a specific look or function.

While other terms relate to the manipulation of hair, they do not precisely capture the concept of interlacing or tying the strands. Twisting refers to the action of rotating strands around each other without securing them in a knot, looping typically involves creating a curved shape but does not necessarily tie the strands together, and plaiting usually involves braiding techniques rather than simple tying. Therefore, knot is the most fitting term in this context.
