Straight, shiny, healthier since you do not need to use blow dryers or flat irons to straighten it all the time! AND very convenient.
Too straight, no volume or body, hair doesn't fall naturally.
I have medium curly hair which used to take over an hour to straighten. I have been doing the Japanese straightening for 3 years now. It is super convenient. Definitely gets your hair straight, however I do not like the fact that it is only stick straight and its very difficult to hold an curl/wave/or hair style.
