One thing to remember about the Agent, Egypt, and Loki, etc....they come with a lot of variation built into them. You can make the hair shorter, longer, fuller, thinner, windswept, etc. I love that flexibility even though I don't do much rendering these days. If you're not anti-postwork, another way to go is a good tidy of the hair after the render...a little smudge here, a little push/pull there does wonders for bed head.
