1. Natural Aging
As we grow older, our body’s ability to regenerate cells slows down. This includes the cells in the nail matrix, which is the base area of your fingernail where growth begins.
2. Dryness and Dehydration
One of the less obvious effects of aging is a loss of moisture, not just in our skin but also in our nails. Drier nails tend to become more brittle and less flexible. This makes any existing ridges appear more prominent and can lead to cracking or peeling.
Frequent handwashing, exposure to soap, or working with cleaning products without gloves can make this dryness worse over time.
3. Nutrient Deficiencies
Another common factor is lack of essential vitamins and minerals, especially:
-
-
- Biotin (Vitamin B7)
- Iron
-
- Zinc
- Magnesium
As we age, our bodies don’t absorb nutrients as efficiently. That means even if you’re eating well, you might still fall short in certain areas — and your nails could be one of the first places to show it.
If you’ve also been experiencing fatigue, thinning hair, or slow healing, it might be worth speaking to your doctor about possible deficiencies.
