I have curly shoulder length hair...

I have curly hair and its a little longer than shoulder length and i was wondering if I should get my hair straightened at one of those yuko system places im only 12 years old but I have been working hard for 2 years to get the money and i finally have it and if I do straighten my hair I will straighten it when I go to Japan in this upcoming school year. Has anyone here gotten it done there and if you have has it worked? If i decide not to straighten my hair what should I do with it because its not very cooperative. The only way I wear it is in a high ponytail or a bun I almost never wear it down because then it gets out of control. And if I do wear it down i I have to put in a ton of gel and hair pray in order for it to be temporarily styled. What products work to keep the curls intact and not frizzy? Does the Curl vive work?

Hi! Wanted to let you know, I use to straighten my hair with a hair straightened every single day and at times thought about getting what you want to have done. I just have to say, don`t do it. It is so bad for your hair and you could be left with frizzy stick straight boring hair in the end. Leave your hair curly, that`s what I do now and I have gotten lots of compliments on it. Straight hair is what everyone has; enjoy what you were born with. I can recommend the curl vive shampoo & con. It is really good, and shampoo every other day. Use Thresame (or how ever you spell it) for a gel and let it air dry. Don`t put so much in though that it makes it stiff, you want your hair to move. I hope I helped! If your hair needs updating just get a small layered look still keeping your curls the length they are. Good luck
