A Bitter Way To Strengthen Biters' Nails

We normally wouldn't want to react to a beauty product by cringing and running away, but that's how we determined that ProStrong for Nail Biters Fluoride Nail Strengthening Solution will do what it promises.

Our brave testers, who admit to nibbling their nails too much, used the pen-like tip to spread the formula across their nails. After letting it dry for a bit, they attempted to take a bite-and we wish we'd gotten the reaction on film.

Their faces were priceless, wincing with disgust from the "chemically" flavor. One tester even opened an emergency door to try to spit out the taste, which lingered long after several swigs of water.

"This will work!" they unanimously decided.

But the solution isn't just for keeping your mouth away from your fingertips. In addition to tasting terrible, ProStrong for Nail Biters Fluoride Nail Strengthening Solution helps nails grow back longer and stronger.

And because it's not a polish, male nail biters are more likely to use it-if they're brave enough, that is!
