Q: Why is nail coloring not allowed for woman? Why do some woman only use it when in woman’s cyle? jazakallah
A: I have not seen any ruling prohibiting a woman from coloring her nails. Some have prohibited her display of it in public before men, but never has its usage been prohibited.
The discussion revolves around the permeability of substances applied to the nails. Henna is considered permissible because water seeps through it, allowing Wudu to be complete even when henna is applied.
On the other hand, nail polish raises concerns as there is evidence that water does not penetrate it, invalidating Wudu. Consequently, individuals holding this belief may choose to use nail polish only when Wudu is not obligatory upon them, or removing it at the time of Whdu.
Side note: It is important for women to recognize the privacy associated with certain matters. If a woman limits the use of nail polish to specific times, such as during her menstrual cycle, and this becomes widely known, it compromises her privacy. However, this does not disallow its usage.
Allah Certainly Knows Best.
