Can a woman uncover her hair in front of her fiancé before the nikaah?

Is it permissible for a female to display her hair infront of her fiance before the Niqah?

Praise be to Allah, and blessings and peace be upon the Messenger of Allah:

If a man has seen enough of his fiancée, within the limits set by Islam, to enable him to decide whether to go ahead with the marriage or not, then it is not permissible for her to uncover any part of her body in front of him until after the nikaah. (See also question #2246 and #2572). And Allaah knows best.
