Wow, I must say the salon you showed us in the first pic is GORGEOUS! (Even if you didn't get your hair done there.)

And I like how it all turned out. Your hair looks amazing!

I've never gotten any kind of extensions so I can't give much of an opinion on one or the other. It looks like clip-in extensions, like the ones made by manic panic would have worked well. You could always try that if you decide you want some color with your black and white!
