Brush all of your hair back to get rid of any knots.
Put your hair up in a high pony tail. Be aware that you cannot pull your hair up tight because this may have an affect on how messy the bun will turn out.
Wrap your hair up in a doughnut shape around the main section of the ponytail.
Once you have gathered all of the hair up in a doughnut shape, tie it with a hair band (preferably the same coulor hair band as you hair tone to make it less visible).
Slightly separate the bunch of hair to get that messy effect.
And you're done! That's how easy it is to get perfect hair in minutes. Which only took me 4 minutes to get the look.
I found that basite spray (dry shampoo) really helps to keep the bun in place. It is currently £2:99 in my local store. But not for long, hurry!
