Q: I know that anything that stops water from entering your skin is haraam (nail polish, wax, etc). But if I only do white nail tips, or any colour nail polish on the tips of my nails which isn’t touching the skin. Is this ok!
A: If it is non-porous then the wudhu is not valid.
And Allah Ta’ala (الله تعالى) knows best.
