I have a habit of biting my nails too. And yes, from my experience, fake nails do stop you from biting them. Especially if they were professionally done because the glue lasts longer (about 2 weeks) and also because you paid for it and don't want to fuck it up, lol.[/QUOT
I have acrylics and my nails grow like crazy under them. Defo stopped me biting
mine last for around 4 weeks professionally done
