A little bit of context before the question: I were at a restaurant and pretty much every woman there was wearing makeup which is common and I don’t really see it as a bad thing but according to some it is bad. So then I saw that a group of women were wearing hijab and makeup and I was confused. The main point of the hijab is for modesty but wearing makeup basically takes away the modesty part as makeup just seems to be a form of attracting attention. Is it permissible to wear makeup and wear a hijab or not?
Is makeup forbidden during hijab? The pattern of makeup should be determined by custom; That is, the general public, people who are in a person's place of residence, if they consider something to be makeup and the woman has that makeup, she should cover it from the non-mahram look. For example, no one calls a simple and ordinary cream makeup. But in general, what is traditionally considered as adornment and makeup, should be covered from non-mahrams.
If your thinking that she shouldn’t wear make up just because it’s a woman only area and sectioned then should she be OK with not wearing a hijab as well? You wear a hijab in public so that men don’t feel sexual desires when looking at you. Wearing make up defeats the purpose of wearing a hijab. There is no grey area with religion. It’s either yes or no, right or wrong.
