It’s fine to have acrylic nails applied during pregnancy, as long as the room is well-ventilated with open windows or air conditioning.
Acrylic nails give off fumes as they are being applied. If you are exposed to a lot of these fumes, it can make you nauseous or sick. This isn’t pleasant, whether you are pregnant or not.
Also keep in mind that you may be more sensitive to acrylic nails during pregnancy, even if you’ve worn them before. You may be more likely to develop an allergy.
Take precautions when having your acrylic nails removed, too. A chemical called acetone is often used to remove acrylic nails and can be left in contact with your nail for up to 20 minutes. This is unlikely to do you any harm, but it is a good idea to:
have your nails removed in a well-ventilated room
wash your hands thoroughly afterwards
If you are at all worried, you can either have your nails filed off at a beauty salon, or go natural. You may find that your nails are stronger and healthier during your pregnancy anyway, so you won’t need false nails.
