Sylver Santika

You will need atleast shoulder length hair. Nice sharp scissors are helpful.

Wet the hair and comb it forward (as neatly as possible) and put it in a pony tail in front of your forehead.
Now cut off the end of the pony tail: the closer you cut it to your face the shorter your hair will be (obviously).

This layering creates a nice cascading effect toward the back.

You can achieve different layering effects depending on where you place the pony tail on your head.
