I can't be terribly specific on color names, since I'm at work, but I tend to do hair in mid-to light colors, ink wash, then highlight. So for blond I'd paint it all a golden tan, wash with a brown ink, and then highlight with at least two lighter colors. Since blonde tends to be slightly transparent/metallic, I wouldn't go all the way to white unless it is a *very* pale blonde.
Unlike most people, I prefer to basecoat humaniod models in white, unless the figure is going to have uniformly dark features.
However, Pogre is an amazing master painter, so maybe you should take his advice instead!
