Back to the topic, the perfect bun. I will share you the 4 easiest step of it. Because I cannot understand Japanese, I made my own steps. Haha
the Japanese instruction
These are the things you need.
I tied my hair like the normal bun we can do. I twirled it (like the photo above). Then, secure it with the ponytails. Afterwards, I put the hair extension to cover my bun and some bobby pins. TA-DA! Finish! As easy as 1-2-3-4..!
The finish product! The perfect bun.. :)
