Comb your hair and put it in a ponytail at the nape. Try as accurately as possible to wear my hair, avoiding the "rooster". Otherwise the hairstyle will look sloppy.

If you want to make a lush beam, then make the bouffant hair.
Secure the tail with a scrunchie. Again comb your hair.

Now gather hair into a bundle and start wrapping them around the elastic clockwise or counterclockwise.
Once the hair is sufficiently strongly tensioned, secure the bun with hair pins or Bobby pins. Can choose how the invisible stud, to beam it looked natural, and a variety of colourful hair clips to make the image more festive.

Secure the result with hairspray.
