Is it okay to show my hair to a prospective husband?

A veiled Muslim girl in the southern Philippines island of Mindanao in February 2008.
There is a guy who has proposed to me.
I know that there is a hadith for the Prophet Mohamed (sala Allahu alehi wasalam) saying it's okay for the guy to look at the girl.
So I am wondering, is this including my hair or just my face??
asalamu alaikum,
the woman has to be covered. it is permissble to cast a glance at the face and palms of a woman whom one intends to marry.
ma salama
