I love finishing a 'do with a messy bun but find that it is usually falling out by the afternoon. This is the only way I have found to style a messy bun that will last the entire day.
To start, make a high side pony.
For a little fun, we added colored hair to the pony.
Next, divide the pony into three sections.
Take one section and make a loop.
Secure the loop with a clear elastic (looking back, I wish at this point I would have added a little gel to keep the flyaways down).
Make loops with the other two sections.
Continue to make loops with the rest of the hair.
Add a few booby pins to secure the loops in place covering any visible elastics.
That is it! This took me ten minutes and lasted all day!
