4. Health Issues
Thyroid Disease
Both an overactive and underactive thyroid can cause brittle nails. If you suspect thyroid issues, a simple blood test can help diagnose and treat these conditions.
Psoriasis
This skin condition can spread to your nails, causing pitting, abnormal nail growth, and cracking. Treating the underlying psoriasis can often improve nail health.
Fungal infections
Fungal infections can damage the nail bed, causing your nails to become brittle and split. Antifungal treatments are effective in resolving these infections.5. Physical stress
Repeated physical trauma, such as using your nails as tools, can cause immediate and long-term damage. Trimming your nails and avoiding misuse can prevent them from cracking and breaking.
6. Age-related changes
As we age, our nails can become drier and more brittle. Including more omega-3 fatty acids in your diet and keeping your nails moisturized can help combat these changes.
