How long do acrylics stay on?

when you get acrylic nails professionally, how long do they stay on your nails?
I've never done it before and need to get it done. so I want to know.

yes or the french manicure
and in two weeks you come back and get them filled(they fill the space where the fake nail grew out)
and I think you can do this a couple times befor they start to fall off
the you need a whole new set,
and warning if you do get them and one falls off your real nail underneith will be very thin and kinda bendy but itll be ok.

about 2 weeks befor you need to start getting them filled, just tell the people at the place to do it and they will no big deal

so I just say when I'm making my appointment that I need to get acrylics on?

the fake nails grow?

no thats why you get them filled, because you know how your real nail grows, well the fake one stays on that same place, so theres a gap where you see your real nail by the cutical, that needs to get filled to cover the part of your real nail,,,hope it helps

I wore tips for years. Like the others have said you will need to get them filled in every couple of weeks and a whole new set every 3-4 months depending on how rough you are on your nails.
