Hello ,

As you age, your fingernails can naturally become weaker and prone to splitting. Try these tips to keep them healthy and strong.

Do:

Avoid fingernail wetness for extended periods — If your fingernails are wet for a long time, they are at greater risk of splitting. Wear cotton-lined rubber gloves during tasks such as washing dishes.
Trim properly — Trim your nails straight with softly rounded corners. Use sharp manicure scissors or clippers, and try to trim your nails after a bath or shower. Carefully clip off hangnails.
Use moisturizer — Dry nails are more prone to split, so make sure hand lotion reaches your fingernails and cuticles.
Clean under your nails — Wash away germs with soap and water. Using a nail brush may be helpful.
Try a nail hardener to strengthen nails — But stay away from products with formaldehyde, as repeated use may weaken nails.
Eat healthy — Consuming a variety of vegetables, fruits, whole grains, lean proteins and healthy fats provides the necessary nutrients for healthier nails.

Don't:

Pick at your nails — Don't bite your nails, pick at your cuticles or pull off hangnails. You may damage the nail bed and increase infection risk.
Overuse nail polish remover — If remover is needed, use an acetone-free remover.
Use your nails like a tool — Don't pry or scrape things with your nails.

Yours in good health,
