Bottom Line
Pros
Cons

If you have dry, brittle nails that crack, peel, and break easily, a protein nail formula can restore their strength and beauty. Chances are, if you have been a serial salon manicure recipient (especially with acrylics and hard-to-remove gel polishes), your nails have become thin. A nail protein formula goes on just like a polish or topcoat, fortifying the nail so that it grows in thicker and stronger. With ingredients like collagen and protein, these often work well as base coats before you apply your normal colored lacquer. And the price is much less than going to the nail salon, at under $15 a bottle for most brands.
