Japanese Straightening 

A way to chemically straighten one`s hair so it remains straight for 6 months to a year. Usually takes up to five hours and can cost anywhere from $80-$300. Damages hair a bit but leaves it stick-straight.

Odette got her hair Japanese Straightened on Saturday, and it was so shiney and straight I couldn`t believe it! Especially since she had extremely curly hair before she got Japanese Straightening.

Jamie: Japa-what? What the hell are you... oh my god AGGHHHHHHHHH

(screams of agony are heard)
