If the makeup prevents the water from reaching the skin, then Wudu is not valid, but if it is just colour or there is a little of it left that does not prevent the water reaching the skin, then Wudu is valid.

The scholars unanimously agreed that what is obligatory in Wudu is to wash each part once, although washing each part two or three times is recommended. However, persisting in washing each part only once deprives the person of more reward.

It is permissible for a woman to wipe over her Khimar (head cover) in the case of necessity, such as when it is very cold, or it is difficult to take off her Hijab and put it back on.

It is recommended for a Muslim to do wudu before ghusl following the example of the Prophet (peace and blessings be upon him). If the shower is done to cool down or to clean oneself, then it does not count as wudu (if wudu is not done before or after it).

What must be done in Wudu is washing the feet; it is not sufficient to wipe them. But the Sunnah shows that one may wipe over the feet only when wearing leather slippers or socks, subject to the conditions that are well known in the Sunnah.
