I'm not just happy with my hair, but I actually like it! It's definitely one of my best features, although I do occasionally have a bad hair day. My hair is long, much like Ayumi Hamasaki's in
this picture; mine is just dark brown in color. I've been growing it out for the past 6 years or so; can't say that I'd regret it.

So if you're considering growing your hair out, I'd certainly recommend it!
On normal days I wear my hair in a high ponytail, because it's a cute and easy hairstyle. But with long hair you at least have options on how to style it, unlike with short hair. Short hair can nevertheless be feminine (see
this picture of Halle Berry for a good example), but it's just not my cup of tea, at least not right now -- I've had to have short hair for long enough, so now I'll enjoy the luxury of having long hair.
