Acrylic tips take a lot of maintaining. Usually, I get my nails done in two or three weeks. Once the acrylic powder and nails are lifting it is best to go get them redone. Sometimes when you wait too long you risk an infection on your nail beds. If I feel like my nails are not lifting I don’t get them done right away. I still recommend going back to the nail salon every two or three weeks for a fill-in.
