Loose Ponytail For Beach Hairstyles
First, you should tie a slightly loose ponytail (either at the neck or at the side) with a hair tie, with the hair tie not lying directly on the head, but a few inches down. Then make a hole between the hair over the hair tie with your fingers and pull the ponytail through the hole from the front to the back.
Finally, pluck the hair around the hole a little, so that no gaps are visible. For an even more interesting effect, you can wrap the hair elastic with a thin strand of hair as desired.
