Trust me, most guys don't care for flat, nothing, long straight hair. Styled straight hair can be wonderful(short or long, it all depends on the cut, look, and does it flatter or fight with the face), but the Marsha Brady look is awful.
Luckily that is already on the way out. Looks like big-hair may be coming back. (Yee-haw for the Dallas look! Back in the early to mid-90's I could easily pick out the Dallas gals when in airports anywhere in the country.)
