After 40, your body naturally produces:
- Less collagen
- Less natural oil
- Slower cell regeneration
This leads to:
- Thinner nails
- More visible ridges
- Slower growth rate
These changes are part of normal aging, just like wrinkles or changes in skin texture.
🧠 5. Dehydration and Lifestyle Factors
Your nails can also reflect daily habits:
- Not drinking enough water
- Frequent exposure to chemicals or detergents
- Excessive nail polish or harsh removers
- Poor hand care routines
Over time, these can make nail ridges more noticeable.
⚖️ When Nail Lines Might Be a Warning Sign
You should pay attention if nail changes come with:
- Pain or swelling
- Nail color changes (blue, dark brown, or very pale)
- Sudden thickening or deformity
- Multiple nails changing at once
These may require medical evaluation to rule out underlying conditions.
