To use a headscarf, simply drape it over your head and tie it under your chin. Alternatively, you can fold it into a triangle and wrap the two ends around the back of your head, securing them with a knot. For a more secure fit, tuck the ends of the scarf under the knot. Adjust the scarf as needed to ensure a comfortable and stylish fit. Experiment with different folding and tying techniques to create various looks.
