The second way: what is needed is two rubber bands. This is especially for straight hair. After combing your hair and tying it, bypass the rubber band and fix it with the rubber band. The ball head with straight hair looks a little stiff. After it is done, gently pull it around the ball head to make it feel a little fluffy.
The head of a plate of meatballs is taboo. Don't comb your hair too tightly in front, even if you comb it, you should pull it gently. Others seem to have sparse hair in the front, even if the ball head at the back is beautiful, it will be greatly discounted.
The third method: first tie up your hair, prepare two rubber bands, divide them into two strands from the middle, then pull one strand clockwise and the other counterclockwise, and you can tie it up.
Actually, it's not that difficult to straighten the ball head. If you are in trouble, you can buy the kind of artifact that specially puts the ball head online. I also have one at home, with a blue ribbon hanging gently on both sides of the ball head. It's very beautiful, and it only takes a few minutes to get it easily.
If you want to pull a beautiful ball head, you can braid your hair first, then roll the ball head and fix it for an hour or two. It will be rolled up after being disassembled, so that the ball head will be more beautiful.
Don't be too fluffy when pulling your hair, it will make the ball head look particularly big and not as beautiful as expected.
