Nails lose moisture with age and exposure to water, soap, and chemicals.
Dry nails become brittle and more prone to ridges.
✅ Solution: Moisturize your hands and nails daily with oils (e.g., jojoba or almond).
3. Nutritional deficiencies (less common)
While not the most common cause, certain deficiencies can affect nail health:
Iron
A severe deficiency (anemia) can cause
nails to be shaped Spoons
(koilonychia), not just ridges
Protein
Weak, brittle nails — the body needs protein to build keratin
Vitamin A, B12, or calcium
May cause dryness or ridges, but are rarely the sole cause.
✅ Note: Mild ridges are not a reliable sign of a deficiency. Blood tests are required for diagnosis.
4. Repetitive trauma or nail biting
Constant picking, filing, or typing can damage the nail matrix.
This can lead to uneven growth and ridges.
✅ Tip: Avoid aggressive manicures and nail biting.
⚠️ When ridges may signal a health problem.
While most ridges are harmless, certain changes should prompt a visit to the doctor.

🩺 What the NHS says about nail changes
The NHS confirms that:
“Most nail problems – including brittleness, ridges, and discoloration – do not indicate a serious condition.”
But they also advise:
If your nails suddenly change or become painful, consult your GP.
If a nail falls off without injury, seek medical attention.
If toenails become too thick to trim, consult a podiatrist.
Early detection can prevent complications – especially for people with diabetes or circulatory problems.
