What Causes Cracked Nails?

Cracked nails can result from various factors that weaken their structure over time.

• Environmental Factors: Prolonged exposure to water, harsh chemicals, or dry conditions can strip nails of their natural moisture, making them brittle and prone to cracking.
• Nutritional Deficiencies: A lack of essential nutrients like biotin, vitamin E, or iron can weaken nails, reducing their flexibility and increasing the likelihood of cracks.
• Improper Nail Care or Product Use: Over-filing, the use of low-quality nail products, or skipping a protective base coat during manicures can contribute to damage.
• Health Conditions: Certain medical conditions, such as hypothyroidism or psoriasis, can weaken nails or cause them to crack as part of their symptoms.

Understanding these causes can help prevent cracked nails and guide appropriate treatment strategies.

How to Identify Different Types of Nail Cracks

Recognizing the type and severity of cracks is crucial to determine the best course of action.

• Surface Cracks vs. Full Splits: Surface cracks typically appear as minor lines or chips on the nail, often caused by external stress or dryness. In contrast, full splits run deeper and may extend across the entire nail plate, often requiring more intensive care.
• Severity Indicators: Minor cracks that don’t affect the nail’s structure can often be treated at home with proper care and hydration. However, severe cracks accompanied by pain, discoloration, or signs of infection may necessitate professional help from a nail technician or dermatologist.

By identifying the type of crack early, you can take the appropriate steps to repair and prevent further damage.

Moisturizing and Hydration

Proper hydration is essential to treat cracked nails and prevent brittleness. Begin by applying cuticle oils or creams rich in vitamins and nutrients. Products like CND SolarOil™ or OPI ProSpa Nail & Cuticle Oil are specifically designed to deeply nourish nails and cuticles, helping to restore flexibility and strength.

For a natural approach, consider DIY remedies like soaking your nails in warm coconut oil or olive oil for 10–15 minutes. These oils penetrate deeply into the nail plate, providing much-needed hydration and promoting repair. Regular use of these treatments can significantly reduce the likelihood of cracks reappearing.

Strengthening Treatments

To prevent future cracks and enhance nail resilience, incorporate strengthening treatments into your routine. Over-the-counter options, such as OPI Nail Envy or CND RescueRXx™, deliver powerful ingredients that repair and fortify damaged nails. These treatments not only treat cracked nails but also help maintain their strength over time.

For those who prefer DIY solutions, a protein-rich nail mask made from egg whites and milk can work wonders. The proteins and calcium in these ingredients help rebuild the nail structure naturally, complementing professional-strengthening products like Gelish Vitagel Recovery for added protection.

Preventive Measures for Healthy Nails

• Apply nourishing cuticle oils like CND SolarOil or OPI ProSpa Nail & Cuticle Oil to prevent dryness.
• Wear gloves when handling harsh chemicals.
• Eat foods rich in biotin, vitamin E, and omega-3 fatty acids to strengthen nails.
• Trim and file nails regularly to avoid splits.
• Use acetone-free removers and quality polishes like OPI Infinite Shine or CND VINYLUX.
