Here’s what those nail lines can actually mean:
🔹 Vertical Lines (most common with age)
These run from the base to the tip of your nail.
👉 Usually harmless and linked to:
Natural aging (very common after 40)
Mild dehydration
Slight nutrient deficiencies (like B vitamins)
✔️ Think of them like wrinkles — but on nails.
🔹 Horizontal Lines (Beau’s Lines)
These go across the nail.
👉 Can be linked to:
Past illness or high fever
Stress or trauma to the body
Conditions like diabetes or infections
⚠️ Deep or repeated lines should be checked by a doctor.
🔹 White Lines or Spots
👉 Often caused by:
Minor nail injury
Zinc or mineral imbalance (sometimes)
❗ Not usually serious.
🔹 Dark Lines (Important)
👉 Could be:
Pigment changes (common in some people)
Rarely, a sign of melanoma
⚠️ If a dark line is new, widening, or irregular → see a doctor ASAP
