fake eyelashes

Q: I have recently started a part time make up course so that I can start earning money to help with expenses for my husband and kids. I have already spent money on the course and on buying the necessary things to do make up for other clients but I realized that it may not be permissible to do make up for others.

1. Would I get the sin for doing make up for women who then go without hijab to functions or mix with non mahrams? Will my income be haraam?

2. Also are we allowed to use stick on synthetic lashes for women who request so? If I had realized earlier I would not have invested in this course and the make up needed

Q: Is prayer acceptable whilst wearing eyelash extensions?

Q:

1. Are we allowed to apply false lashes?

2. Can I use a curler (a tool to curl lashes temporary) and mascara (to lengthen the lashes temporary)

3. Are alcoholic perfumes/sprays/body mist, etc. not allowed to perform salah? I heard that if you are using perfumes which contain alcohol, you can't perform prayer in that condition, is that true?

Q: Are fake lashes and fake nails allowed or not, like fake hair extension (wig)?

Q: I wanted to know if it's permissible to wear false eyelashes? And if there's one type that we aren't allowed to wear?

Q: Please can you advise if it is permissible for females to use fake eyelashes and make wudhu?
