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?
Makeup is an adornment. As such it falls under the category of zeenah (adornment) that were asked to be concealed by Allah in the verse of Surah Noor:
And tell the believing women to reduce [some] of their vision and guard their private parts and not expose their adornment except that which [necessarily] appears thereof and to wrap [a portion of] their headcovers over their chests...
Therefore, if a woman wears makeup, she has to conceal it from the non-mahram and it is not permissible to keep it exposed in front of them.
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.
