I think it's beautiful, but sometimes I hate it. My hair is naturally curly, but also naturally very frizzy. I used to straighten it every day, but now I'm trying to embrace my curls. Embracing them and taming them are two very different things, though.
I do not have naturally curly hair, but I love curly hair, and I have considered doing it permanently. But some friends I have with curly hair do not like it and wish it was straight. One of my best friends though has curly hair, and she likes it. Actually a guy told her before they met he wanted her to straighten it when they met and she got mad and didn't talk to him after that. But I totally dig the curly hair.
Naturally curly hair is beautiful, especially when it's long and not frizzy! Sleek, thick, long curly hair is something I really envy. Frizzy is completely different, mine goes frizzy without me straightening it, and it is ugly! Completely different to curly.
