About the straight hair comment, oh please, come off your high horse. You act as if little girls with straight hair never have anyone curl it because they think it looks pretty curly. There is nothing wrong with people trying out a new look. I will have to look again, but it appeared that your hair has some color in it. THAT IS ALSO A NEW LOOK.
People like to experiment. My neice thinks she looks cute if my sister straightens her hair. I prefer her curly hair. If there are no chemicals to make things permanent, I don't see any harm in people switching up their look. How many women get their hair blown out for a special occasion? How many women get their hair curled or use a waving iron for a night out?
