Krysten Ritter looks like the student she portrays in the television series CW in “Veronica Mars” as Gia Goodman. Her hair is long and held back by a hair band with a school fashion type of bangs.
To have her curly wavesuse a medium sized curling iron and wrap around vertically and with a large toothed comb lightly go through the hair letting the hair stay where it goes. Bring the hair band through the top and back tucking into the hair on the sides.
For versatility you could also use ornamental hairpins that have flowers or jewels on each side of your hair.
