Almost every client and company I've ever worked with has ached to reach the "blonde", but I continue to advise them to pay attention to the brunette (and redhead and all the other variations of hair colour). The long tail is chunky and has more possibilities than anyone can imagine.

The thing is, the brunette is gorgeous and interesting, but she just wasn't as noticeable. She's also not used to the attention, so is much more approachable. It's up to you to look past the "blonde" and pay attention to the ignored, underrepresented and under-served.
