In which direction should fabric strips be pulled during hair removal treatments?

During hair removal treatments, fabric strips should be pulled opposite to the direction of hair growth. This technique is essential because it allows for a more effective removal of hair from the follicle. Pulling in the opposite direction helps to minimize discomfort by reducing the resistance against which the hair is being pulled. When the strips are pulled away from the skin in this manner, it effectively uproots the hair, leading to a cleaner and more efficient hair removal process.

The other options do not support optimal hair removal techniques. Pulling in the same direction as hair growth would allow the hair to break at the surface rather than being removed from the root, resulting in less effective hair removal and potential irritation. Pulling at an angle to hair growth may not provide the necessary strength to adequately extract the hairs. Lastly, using a circular motion does not align with the directional technique needed for effective removal and could cause unnecessary irritation to the skin. Thus, pulling the strips opposite to hair growth is crucial for achieving the best results in hair removal treatments.
