Check this out. I just read this on a blog:
First impressions count. Many closet curlies are married to a flat iron because they think men prefer the smooth, straight look over curls or kinks. And when you can maneuver your mane in either direction, you have the option of changing your visual impression when meeting someone new.
But should you? And would it really make a difference?
To find out, I embarked on an unscientific social experiment. Newly single in New York City, I joined a popular online dating service and posted two profiles. They were identical in every way—except one. The first profile included a picture of my hair flat-ironed straight. For the other, my hair was naturally curly. After one month showcasing the straight profile and the next month curly, more than twice as many men responded to the straight look.

More Details:
  • The straight profile was viewed 1,606 times for the month, while the curly one received 1,063 views during the month it was posted
  • The flat-ironed look 181 [COLOR=#0072BC ! important][COLOR=#0072BC ! important]emails[/COLOR][/COLOR], compared with 60 for the curly profile
  • On the flirtatious side, the stick-straight profile received 120 winks, while curly locks caught winks from 60 men
  • In about 10 percent of the dates, hair made a difference, while confidence was the driving factor in the remainder of the connections
