Do you that the humans want/like totally the opposite of what they have? Like the grass is always greener on the other side of the fence? My hair is straight and I can kill for curly hair and then, there's a friend of mine who has curly hair but would do anything to have straight hair. But tbh, you'd really lose your charm if you get your hair straightened or vice-versa. Stick to your natural locks and you'd look the prettiest.
PS: It's okay if the straightened hair lasts temporarily, ie, only a few days or so.
Definitely curly for me :) it took me forever to love my curls but now I adore them :) be happy with what you have! Curly hair gives you a lot of options that straight hair doesn't. You just have to learn how to work with it
