Top 5 Remedies for Brittle Nails

Nails can suffer from various issues such as brittleness, pits, discoloration, flaking, and ridges, among other frequent and unpleasant problems. Brittle nails, a common result of aging, typically appear dry, cracked, or split. They may grow slowly or feel fragile and break easily.

Nail issues might stem from relatively minor conditions like brittle nail syndrome, characterized by excessively weak nails, often due to moisture deficiency. A shortage of iron or zinc may also contribute to the problem [source: University of Maryland Medical Center]. However, more serious conditions such as hepatitis, jaundice, lupus, or heart disease may also be reflected in nail abnormalities. Always start by investigating basic causes like fungal infections, reactions to nail polish, or trauma-induced bruising.

There's ongoing discussion about whether brittle nails are primarily caused by a lack of protein or moisture. As a result, most treatments for brittle nails focus on one of these two factors. In this article, we’ll explore five strategies for improving nail health and explain why a candle might be exactly what your nails need.

5: Vitamin Supplements and Biotin

Vitamins are essential for supporting the body’s functions, and nails are no exception. A deficiency in iron or zinc can negatively affect nail health, and a simple multivitamin can often help. Look for one that includes vital nutrients like niacin, iron, calcium, and vitamins A and C.

A vitamin B complex that includes biotin is frequently mentioned as crucial for nail health. In addition to being found in certain supplements, biotin can be sourced from oatmeal, bananas, mushrooms, peanuts, soy, and, for those who can handle it, some animal organs. The exact mechanism by which biotin strengthens nails is unclear, although the vitamin has been shown to strengthen horse hooves. In one study, women who took 2.5 milligrams of biotin daily for at least six months experienced nails that were 25 percent thicker [source: Healthnotes].

Biotin is present in a variety of foods, so most people consume sufficient amounts, except in specific situations such as in individuals with alcoholism, those who eat excessive amounts of raw egg whites, or those on prolonged courses of antibiotics. Many pregnant women suffer from biotin deficiency, which can cause birth defects, making prenatal vitamins vital [source: Healthnotes]. Some non-pregnant women also take prenatal vitamins for their supposed benefits to hair and nail health.

Much of the information linking supplements to nail health is based on personal anecdotes rather than solid scientific evidence. However, there is some support for the idea that glucosamine, commonly used to treat osteoarthritis, may be beneficial. Gelatin and horsetail, a plant known for its medicinal properties, are also used to treat brittle nails, though evidence supporting their effectiveness is limited or inconsistent [source: Healthnotes]. (Gelatin is derived from animal hooves and connective tissue, and is a popular treatment at many nail salons.)

4: Super Moisturizers

In many cases, brittle nails are primarily caused by a lack of moisture, similar to how dry skin can cause your epidermis to become cracked or flaky [source: Wadyka].

Over-the-counter moisturizers, such as Vaseline, can be effective in maintaining healthy nails, while some people rely on home remedies like a blend of egg yolks and milk. Additionally, there are creams designed to lock in moisture, including Aquaphor and Trind Nail Balsam.

In the past decade, a category of creams known as super moisturizers has gained widespread popularity in the nail care industry. These creams, enriched with vitamin E, avocado oil, and shea butter, are applied not only to the nails but also to the surrounding skin.

3: Fortified Nail Polishes

Nail polishes aren't just for enhancing appearance—they can also be beneficial for nail health. Fortified nail polishes are infused with additional vitamins and minerals, aiming to improve nail condition. Some brands make bold claims, like Sally Hansen Miracle Cure, which touts laboratory results stating that nails can become 50 percent stronger in just three days [source: Sally Hansen].

It’s not only about the polish you apply, but also the remover you use. Some nail products, especially removers, contain harmful chemicals. Avoid any products with formaldehyde, acetone, or toluene, which can damage nail health. Formaldehyde, which is used in embalming, and acetone can dry out your nails. Ingredients like camphor and phthalates may also cause allergic reactions.

2: The Natural Approach

Steer clear of nail products that could trigger an allergic reaction, especially those containing the ingredients mentioned earlier. Additionally, avoid nail hardeners—brittle nails are already too hard, and these hardeners can cause allergic reactions in some individuals. Moisturizing your nails is a much better option.

It's important to leave your cuticles intact as they play a crucial role in nail health. Excessive trimming can increase your risk of infection and may even lead to nail deformities. If a hangnail or excess cuticle is bothersome, carefully trim them with scissors, but don’t overdo it.

Take breaks from nail polish every so often. This allows your nails to breathe and gives you a chance to check their condition to ensure no issues are hiding beneath the polish. Additionally, moisturizing creams work more effectively on nails that aren’t coated with polish.

Limit your use of nail polish remover, applying just enough to remove the polish. As noted earlier, avoid removers that contain harmful ingredients like formaldehyde, which can dry out your nails.

It's important to let your nails breathe, but also pay attention to how environmental conditions affect them. Cold and dry air can cause them to crack.

1: Protect Your Hands

Keep your nails safe by shielding your hands. Gloves are essential, especially in colder weather or when washing dishes, as constant hand washing can cause water to penetrate the nails, leading to swelling and increased brittleness.

Keep your nails trimmed short. Long nails are more prone to damage and can interfere with daily activities. This is especially true for office workers who use their hands frequently. Be mindful, such as by gently closing drawers to avoid trapping your fingers in them.

Poor circulation could be contributing to brittle nails, so if you suspect this is the case, consult with your doctor. Other health conditions, like an underactive thyroid, can also affect nail growth and should be addressed with a healthcare professional.

Watch out for signs of fungal infections, which are more common in older adults. While these infections can be treated, ineffective creams or potential side effects from oral medications might make some doctors recommend simply monitoring the infection instead of immediate treatment [source: Brody].
