I live in Boston ma. In the summer it gets quite humid here.I have long thick wavy to curly hair. It takes me about an hour and a half to get it straight when I go out and in the summer still might get a bit wavy a frizzy once I go outside to the humidity. Has anyone had it done? Any hair dressers? I need some advice. I had it test stranded and the hairdresser said it would be ok to do. Does it run your hair? Should I do it? Any help would be appreciated
