I was always wondering how does the perfect hair look like? What do guys find attractive? I always preferred the big bouncy curls, because my hair doesn't want to be straightened: the waves return in an hour. What color is trendy today?
There's no such thing as "perfect hair". It all depends on the person, the clothes and the person's face. Someone will look great with straight hair, while someone else will not. In general, I don't like it when girls overdo their hair, like blow it up too much or make it look too eccentric. Something normal, natural & elegant will do just fine.
No such thing as perfect hair because hair looks different on every person. Experiment with styles and colors, look in the mirror, and see which combo looks best on you. But don't forget to still change things from time-to-time.
