What Are Brittle Nails?

So common they hardly rate as a condition, brittle nails are often nothing more than the body’s response to environmental conditions. A trip to the nail salon can be an informative and satisfactory first step to making brittle nails beautiful.

It’s not difficult to identify brittle nails: they split, peel, and break easily. It is nearly impossible to grow nails out when they are brittle, because once the nails have any amount of free edge, they split and break.

Brittle nails can be caused by medical conditions such as a thyroid problem or a hormone imbalance, but more often than not, brittle nails are caused by an interaction with the environment. “Here is a simple way to look at brittle nails,” says Dr. C. Ralph Daniel, clinical professor of dermatology at the University of Mississippi Medical Center in Jackson, Miss, and associate clinical professor of dermatology at the University of Alabama, Birmingham. “If nails are hard and brittle, they have too little moisture. If they are soft and brittle, they have too much moisture,” he says. Brittle nails don’t usually cause clients physical pain. However, brittle nails are often the result of nails that lack moisture. If the nails lack moisture, it’s likely the skin will lack moisture also. The skin surrounding the nails may crack, split, and bleed. This may be painful for the client, but the pain wouldn’t be directly caused from brittle nails.

Dr. Daniel says clients will often ask him if their bodies lack a particular vitamin, or if brittle nails are an indication of a larger, internal problem. Daniel says one question he asks patients to determine if brittle nails are a symptom of a more serious problem is this: Are your toenails brittle? Most clients respond no. “If fingernails are splitting because the body lacks a vitamin, the toenails would split too, because both are formed from the same material in the body,” says Dr. Daniel. When fingernails are brittle, but toenails are not, there’s a good chance that the nails are brittle because they are being exposed to something in the environment.

Detergents, soaps, or other allergens could cause the nails to split, but a common culprit of splitting nails is plain, everyday water. People who are in and out of water all day long are more likely to develop brittle nails. This could include nurses and bartenders, or someone who is particularly conscientious about clean hands. Just as the skin in the hands gets dry and needs to be rehydrated, so, too, do the fingernails. Clients who live in an area of low humidity or who heat their homes with forced hot air also are more apt to develop brittle nails because of the lack of moisture in the air, says Dr. Daniel.

Applying and removing polish frequently can also dehydrate nails, causing them to become brittle. Clients who remove their polish more than once a week may complain that their nails have begun to split. Techs can remind clients to moisturize hands as one step in their at-home polish change.

An unavoidable factor that contributes to brittle nails is age. “As we age, our bodies lose the ability to hold moisture,” says Dr. Daniel. Don’t think retired clients, either. The body’s ability to retain moisture begins to change at around age 35. Techs should be aware of this natural change and be prepared to recommend moisturizers, vitamins, and cuticle oils to clients whose nails show signs of aging.
