Now, you can follow the how-to-do steps and make a style by your own.
Step one: create a centre parting staring from your middle of forehead to the nape of your neck.
Step two: leave a few strands of hair out from both two side, especially the ones that frame your face. This is saved for the final finishings, do not use it in the following step.
Step three: pull the two sections back into a ponytail on either side. Make sure that you keep it close to your neck. Secure them with elastic band.
Step four, now begin braiding the ponytail into a traditional 3-strand plait. After you braid to the end of the hair, secure it with elastic band. Please aware that you should not leave too much hair out, rather, keep braiding till the end.
Step five: wrap the plait in a circle around the origin of the ponytail. For secure it, the u-shaped bobby pin can be fixed. Do it the same on the other side.
