How does fluoride help to strengthen the nail? Will Natural 10 Beauty help my thin, weak nails?
Both teeth and nails have something very important in common: They both contain calcium. Just as the fluoride in toothpaste combines with the calcium in the tooth to form a very hard protective surface, the cosmetic-grade fluoride that is in our Fluoride Strengthener combines with the calcium that is already in your nail to double nail strength in as little as 4 weeks.
