Answered by Ustadha Sulma Badrudduja
Question: I have grown up to believe that after making wudhu (female) it is wajib to cover the hair and other parts of the body in order to keep one’s wudu intact. If a ghair mahram sees the female’s awra, it nullifies her wudu? Is this correct?
Answer: Wa alaikum assalam wa rahmatullah,

A woman’s wudu is not nullified by a non mahram seeing her hair or any other part of her `awra. Though covering her `awra is obligatory, it does not affect her wudu.
There is a complete list of all the things which nullify wudu here:
