Types of Nail Ridges & Their Possible Causes

Types of Nail Ridges & Their Possible Causes

1. Vertical Ridges (Running from Cuticle to Tip)

• Common Cause: Aging (like “wrinkles” in nails—often harmless).

• Other Possible Causes:

  • Nutrient deficiencies (iron, vitamin B12, zinc, or magnesium).

  • Dehydration (brittle nails with ridges).

  • Mild trauma (from manicures or nail biting).

2. Horizontal Ridges (Beau’s Lines)

• Common Causes:

  • Severe illness or stress (e.g., infection, high fever, surgery).

  • Chemotherapy or other medications.

  • Zinc deficiency or malnutrition.

  • Diabetes or circulatory issues (if recurring).

3. Pitted or Irregular Ridges

• Possible Causes:

  • Psoriasis (often with thickened, discolored nails).

  • Eczema or chronic inflammation.

  • Autoimmune disorders (like alopecia areata).

When to See a Doctor

• Ridges appear suddenly or worsen quickly.

• Paired with nail discoloration, swelling, or pain.

• You have other symptoms (fatigue, hair loss, skin changes).

How to Improve Nail Health

• Hydrate and moisturize nails/cuticles.

• Eat a balanced diet (protein, biotin, iron, vitamins A/C/E).

• Avoid harsh chemicals (use gloves when cleaning).

• Gentle nail care (file in one direction, avoid excessive buffing).

Most vertical ridges are harmless, but horizontal or deep ridges warrant attention. If in doubt, consult a dermatologist! 💅✨
