Is Mascara Prohibited in Islam?
Question

We have learned from the scholars that wearing false eyelashes is prohibited. Is it permissible to put mascara on the eyelashes, which makes them thicker and makes them look longer? Please note that we do not use kohl if we put mascara on.
Praise be to Allah.There is nothing wrong with using mascara because it is a kind of permissible adornment like kohl , but that is on condition that one does not appear wearing it in front of non-mahram men. It does not matter that it makes the eyelashes look longer or thicker; rather false eyelashes are not allowed because they come under the same heading as hair extensions which are regarded as objectionable. 
It should be noted that with some types of mascara Wudu is not valid because they prevent the water from reaching what is beneath them
