We have learned from the scholars that wearing false eyelashes is haraam.
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 Allaah.
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. Please see the answer to
question no. 39310.
It should be noted that with some types of mascara wudoo’ is
not valid because they prevent the water from reaching what is beneath them.
Please see the answer to question no.
