IOD has a Naturaluxury line that's soap free, paraben & sulfate free. Pet Head is another good one, also cruelty free. But they're not fragrance free. I carry both in my site.
Warren London is another excellent one, but I am all sold out on their shampoos.
This link talks about sulfates & parabens & good alternatives:
