If you have nails that break easily, here are some tips. Only rarely is a disease or vitamin deficiency an issue, despite what you may read. (If your fingernails split, but the toenails are strong, then an external factor is the cause.) Usually, brittle nails are simply due to a lack of moisture. Brittle nails are worse in winter when there is low humidity and dry heat indoors.
Nails become more brittle from constant wetting and drying. Don’t wash dishes with your bare hands. Wear dry, cotton-lined rubber gloves, available at most drugstores.
Drink plenty of water. If you’re dry, your nails will be.
Apply lotions containing alpha-hydroxy acids or lanolin containing lotions such as “Elon” to the nails after first soaking nails in water for 5 minutes.
Some fingernail polishes contain formaldehyde, which can irritate skin and nails. If you think your polish is causing problems, switch to a polish that doesn’t contain formaldehyde, or avoid polish altogether.
Biotin (a vitamin) taken by mouth is beneficial if you have a year-round issue. It takes at least 6 months, but does really help at least 1/3 of the time. (Do not take this if you are pregnant.)
Eat Jell-O. Seriously, gelatin helps many people (though not as reliable as Biotin). Or you can mix your favorite flavor of Jell-O and drink it while it’s still warm, if you don’t feel like waiting to refrigerate it. Calcium also helps some people.
Keep a natural nail shape. Round the tips in a gentle curve. File in the same direction as the nail grows and not in a “back and forth” motion.
Gently remove nail snags as soon as you can.
Avoid using metal instruments on the nail surface to push back the cuticle.
One reader says, “Apply petroleum jelly to your nails at bedtime. Cover them with cotton gloves and your nails will retain more of the moisture.”
