help with japanese hair straightening!??

Hello,

I've done my research and I really want to get japanese hair straightening done (thermal reconditioning or straight perm in other names) to my hair. I guess the Yuko system is the way to go.
The problem is that I live in Amsterdam (Netherlands) and although I have looked a lot I haven't found a salon or studio that does that around here. Does anybody know about it and can help me? I'm getting desperate.

I've been using flat iron for a year now. My haircut was shorter for a while but now it's longer, like 5 or 6 inches. But I'm concerned that my hair will get really dry and smashed from almost daily use of flat iron. Although I think it's quite good one (ceramic, Efaloc professional tools). And in addition to that it's really annoying to do that process after every wash and if the hair get wet after swimming, rain or sweating it's all over again.

I'd be super grateful from your help!!
