Just say "curly hair." I really had NO idea what you meant by that.
Amy, a young girl with curly hair, was carrying her purse in her left hand when she left the office... there are many ways you can combine these thoughts. I'd prefer two sentences.
Amy was a young girl with curly hair. She left her office, carrying her purse in her left hand.
1. It's "wearing", not "wearng". But I think you just mistyped.
2.I've no idea what is a 'foam-formed curly hair'. Is the hair aritificially made? If it is, it is called "wig", not "hair", and I still have no idea what is "foam-formed".
The word "foam-formed" formed by my imagination is false. However, it's original meaning is that Amy has a perm and gets a bodywave that makes her hair looks like bubbles.
