This style only took me 5-10 minutes to do but it does take a lot practice. If you can do french plaits on yourself then this should be do-able for you. If not you could always ask someone who can.
I tipped my head upside down as far as I could and started to plait right from the back of my neck..adding thin strands as I go. I then simply wrapped the ponytail around itself once to make the bun. Make sure your hair is thoroughly brushed before styling. If you don’t want a bun you can always leave it as a free hanging ponytail or style the end how you like.
