Your middle finger nail is likely breaking due to brittleness caused by fluctuations in moisture levels (too dry or too moist), or, less commonly, underlying health issues or the natural aging process.
Here's a more detailed look at the possible causes:
Potential Causes of Brittle Nails:
-
Moisture Imbalance:
- Too Dry: Frequent hand washing, use of harsh soaps or cleaning products, and exposure to cold, dry air can strip your nails of natural oils, making them brittle and prone to breakage.
- Too Moist: Prolonged exposure to water (e.g., frequent dishwashing without gloves) can weaken the nail structure, leading to splitting and breaking.
-
Nutritional Deficiencies:
While less common, certain deficiencies can contribute to nail problems.- Iron Deficiency (Anemia): A lack of iron can result in brittle, thin, or spoon-shaped nails (koilonychia).
- Other Deficiencies: While less directly linked, deficiencies in biotin, zinc, or other vitamins and minerals could potentially impact nail health. Always consult a doctor before taking supplements.
-
Underlying Health Conditions:
In some cases, brittle nails can be a symptom of an underlying medical condition.- Thyroid Problems: Both hypothyroidism (underactive thyroid) and hyperthyroidism (overactive thyroid) can affect nail growth and strength.
- Other Conditions: Rarely, nail changes can be associated with other conditions, such as psoriasis or fungal infections.
-
Aging:
As we age, our nails naturally become thinner, drier, and more brittle. -
Trauma:
Repetitive trauma to the middle finger nail, such as typing, playing musical instruments or pressure from ill-fitting gloves, can cause weakening and breakage. This is especially likely if the nail is already somewhat compromised.
What You Can Do:
- Moisturize Regularly: Apply a moisturizing hand cream and cuticle oil several times a day, especially after washing your hands. Look for products containing ingredients like shea butter, jojoba oil, or vitamin E.
- Protect Your Hands: Wear gloves when washing dishes, gardening, or using harsh chemicals.
- Avoid Harsh Chemicals: Use gentle, soap-free cleansers and avoid nail polish removers containing acetone.
- Stay Hydrated: Drink plenty of water to keep your body and nails hydrated from the inside out.
- File Properly: File your nails in one direction to prevent splitting.
- Consider Biotin: If your doctor advises it, a biotin supplement may help strengthen your nails. Always consult your doctor before starting any new supplements.
- Consult a Doctor: If your brittle nails are accompanied by other symptoms or don't improve with home care, see a doctor to rule out any underlying medical conditions.
In summary, the breakage is most likely from external factors that are easy to address with changes in your habits. The less likely, but more impactful causes require intervention of a medical professional.
