I've recently heard of the BKT (Brazilian Keratin Treatment) to relax curly hair and even improve the condition. I became interested in it but I wanted some other opinions about it. Have any curlies here tried it? I just want a change. With curly hair, you can't do much to it style wise. I want to have layers and bangs without worrying about it looking weird. And I also want to be able to put my hair up in a pony and take it out whenever I want without it looking horrible.

I just want a change for a little while and the BKT isn't permanent so I thought I'd give it a go but I want some reviews on it. Maybe before/after pictures?
Curls: 3a/3b
