As'salam alaikum,

Will you please let me know if a woman can use the nail polish? some Islamic scholar say, if a woman uses nail polish, it is prohibited because when she makes wudhu, it is not completed. Will you please clarify this issue in details.

Jazak Allah khayran.

It is permissible for a Muslim woman to use nail polish and it does not invalidate ablution. However, if nail polish is of the kind that prevents water from reaching the skin, it is obligatory to remove it before performing ablution. If otherwise, and it does not prevent water from reaching the skin, like dye and Hinna, it is not obligatory to remove it.
