Fingernails consist of keratin, a protein that is also found in the skin and hair. Healthy fingernails are smooth in texture, even-colored in appearance and free of lines and ridges. Weak, soft and thin nails are most often the result of vitamin and mineral deficiencies in your diet. Problematic nails can sometimes indicate more serious illnesses such as diabetes and heart disease. Developing stronger, more durable nails begins with treating your nails with care and avoiding harmful nail practices.
Exposure to Harsh Chemicals
Avoid directly exposing your nails to harsh chemicals such as household cleaners and detergents. These products contain abrasive ingredients that leave your nails vulnerable to damage, resulting in dry, weakened nails. Wear rubber gloves to protect your nails from damage. Nails exposed to cold winter weather are vulnerable to damage as well; wear winter gloves to protect both your hands and nails from the cold.
Bad Nail Habits
Poor nail habits are a leading cause of weak nails. According to MayoClinic.com, habits such as nail biting result in damaged nail beds. If you have hangnails, avoid pulling them off; this leads to torn skin, thus leaving your nails open to bacteria and fungi. Avoid using your nails as opening tools. Opening cans or prying lids open using your nails nails makes them brittle, weak and prone to chipping.
Acrylic Nails
Using acrylic nails for prolonged periods of time leads to nail damage. The glues and gels used to apply acrylic nails to your own nails may contain harsh chemicals. Nail drilling tools used to file your nail down for better application of the acrylic nail can damage the layers of your nails, making them softer and thinner. Use acrylic nails sparingly and never attempt to remove them yourself; prying acrylic nails off may cause severe damage to the outer layers of your nails. Always have acrylic nails professionally removed. Use caution when selecting a nail salon; choose those with the best hygienic practices.
Nail Hardeners and Polish Removers
Overuse of nail hardeners directly contributes to weakening your nails. The website Mother Nature states "Formaldehyde-based products do make your nails hard, but they do it by drying them out." If you already have weak nails, use of these products makes them prone to further damage. Refrain from using hardeners containing formaldehyde altogether and choose those with gentler ingredients.
Health Conditions
Weak nails may be caused by existing health conditions such as psoriasis or hypothyroidism. Hormonal imbalances related to your period, menopause or aging may also cause your nails to become weaker. Low estrogen levels lead to dehydration, resulting in dry, cracked, brittle nails. Genetics can play a part in weak nails. If this problem runs in your family, you are more likely to suffer from it. See your doctor if you have persistent nail problems.
