A fishtail plait
If you don't know how to do one of these there are plenty of tutorials on Youtube. It's a plait using two strands of hair rather than three. Once you know how to do one it's really simple and quick and makes it look like you've put a lot more effort into your hair than you really have! Tie with either a clear elastic band or mix it up with a bit of ribbon.
This is a super quick look to achieve. I slept with a plait in my hair and then spritzed some Schwarzkopf got2b Texturizing Salt Spray through my hair in the morning. Et voila!
Half up twist
The ten second hairstyle, just twist the top half of your hair into a bun and secure.
A plaited fringe
You can get away with this being a bit messy so depending on how much time you have you can make it as neat or keep it as messy as you want! I started right round at my left ear and french plaited across my head, pinning at my right ear.
This is actually a bit messier than I would usually want it but I was in a real rush this day! Just back comb as much of your fringe and top of your hair as you want, spray and pin.
