I have a secret. I had a big nail biting problem for the past 15 years. I'm talking about biting my nails enough to cause bleeding and fingers icky enough to look like something out of a zombie movie. But the good news is, "had" is in the past tense. :)
About 2 months ago, I stopped at a salon called Dashing Diva after work. After getting a manicure, one of the girls recommended I get their anti-bite nail polish called "Don't Bite." It was only $7, so I gave it a shot.
To this day, this has been one of the best decisions I have ever made. This stuff is activated once you get your nails in your mouth, setting of the formula to leave a very bitter taste. The taste even lingers a minute or two afterwards, which pretty much makes you learn your lesson once and right. The nice thing is is that it leaves off a nice shine, making it look like a professional nail shine.
Ever since then, I have stopped biting my nails completely. If this works for me, one of the worst nail biters ever, it should definetly work for others. I highly guarantee it.
What are you waiting for? Spare your nails. :)
