Looking for high res pictures for my website...

Hi, I'm currently rebuilding my website and wondered if any one knows where i can get some really good hair pictures to put on it. I'm a Label.m stockist and have access to their artwork but i don't want my website to look like an extension of theirs. I'm willing to pay for the pictures as i have used iStock photo before but want something a bit more specialist in hair photography.

Any help will be great. Thanks.
