This hairstyle is really easy and has a neat look to it.
It's easiest when using wet hair for this one. Create a small off-centered part in the top of the hair and then comb everything straight.
Grab some hair from along the hairline that is right above each ear. Twist those two side over the combed hair and combine it at the back of the head with an elastic. (Have the combined area somewhat low on the back of the head.)
Now gather two more sections of hair just below the first two and twist them together at the back of the head as well and combine them with another elastic. You should now have two elastics at the back of the head and a section of hair still hanging that is combed straight.
Grab all of that hanging hair and roll it up over the two elastics. Tuck it underneath the elastics creating a roll. Secure it in place using bobby pins and add any hair accessories you like to finish it off.
