The building blocks of healthy nails

Nails are primarily composed of keratin, a protein that also forms hair and skin. Strong, resilient nails need a steady supply of essential nutrients such as:

• Vitamins and minerals: Vitamins A, B, C and D, along with minerals like zinc, iron and calcium, play crucial roles in nail health. You can find them in legumes, leafy greens and colorful fruits.

• Protein: A protein-rich diet is essential for building and repairing tissues, including nails.

• Omega-3 fatty acids: These fatty acids promote healthy nail growth and can help prevent breakage.

5 signs your nails are healthy

What do healthy nails look like? Here are five common characteristics:

1) They’re smooth and grooveless.

Ridges or dents on your nails can indicate minor damage, such as from a bump or a scratch, or signal certain health conditions. Healthy nails are typically smooth and even.

2) They’re flexible.

Imagine your nails as tiny shields, constantly exposed to the elements. To withstand this, they need a balance of flexibility and strength. Nails that bend without breaking are a sign of good health, while brittle nails might indicate the need for a new nail care routine.

3) They have a consistent texture.

As we age, it's normal for nails to lose some of their strength. They might become slightly more brittle, and that's okay. However, if you notice a sudden shift in texture and can't pinpoint the cause, check in with your dermatologist.

4) They’re hydrated.

You can think of your nails and cuticles as a team. When cuticles are dry and cracked, they become more susceptible to irritation. Hand creams and targeted nail treatments can help hydrate both nails and cuticles, keeping them healthy and moisturized.

5) They’re pink in color.

Yellow nails can be a cause for concern—but not always. Frequent nail polish use can stain the nail plate (the hard part of your nails). If you find yourself in this position, try taking a polish break. However, if new nail growth appears to be yellow, it's best to consult a dermatologist to rule out a fungal infection or other concern.

Tips for healthy nails

Even if your nails look as healthy as could be, implementing a few daily habits can help keep them that way.

Do your best to protect your nails.

Cleaning gloves work to safeguard your hands against harsh household chemicals.

Avoid excessive nail polish use.

If you can, take a break between manicures to let your nails rest.

A balanced diet can help.

Getting enough vitamins, minerals, protein and omega-3 fatty acids can contribute to nail health.

Work to stop biting your nails.

While easier said than done, stopping nail biting can help prevent damage to the nail plate and potential infections.

Try a nail strengthener.
