Yes they are safe. I am an instructor at a cosmetology school and am around it everyday. Im 25 weeks with baby #2 and never had any problems. As the ladies said above, just make sure your in a well ventilated salon. They also have organic products you can mention to your stylist if that would make you feel better.
This is my second and both babies I git my nails done with no problem.
My friend does them at her house, but another friend said it was harmful to the baby! Just a little confused !
Yes it is safe just make sure the place you get it done at is well ventilated you could ask them to open the doors if not wear a mask because of the fumes but every place I went to they had no problem keeping the doors open while I was there and it's hot here
I get Mine done every two weeks and baby is fine:)
