What Causes Weak Nails With Ridges?

White Lines on Nails

Weak nails with ridges can be caused by various factors, including:

  • Aging: As people age, their nails may become weaker and develop ridges due to decreased cell turnover and changes in the production of keratin, the protein that makes up nails.
  • Nutritional deficiencies: Inadequate intake of essential nutrients, such as vitamins (especially biotin, vitamin C, and vitamin E), minerals (such as iron, zinc, and calcium), and protein, can weaken nails and lead to the development of ridges.
  • Dehydration: Lack of proper hydration can affect nail health, making them more prone to dryness, brittleness, and ridges.
  • Medical conditions: Certain medical conditions can impact nail health, leading to weak nails with ridges. Examples include thyroid disorders, psoriasis, eczema, fungal nail infections, anemia, and autoimmune diseases.
  • Medications: Some medications may have side effects that affect nail health. For example, chemotherapy drugs, retinoids, and certain antifungal medications can cause nail changes, including weakness and ridges.
  • Trauma or injury: Physical trauma or injury to the nail bed can cause damage to the nail matrix, where nail cells are produced. This damage can result in the formation of ridges as the nail grows out.
  • Excessive manicuring or nail treatments: Overuse of nail polish, nail polish removers, acrylic nails, or gel nails, as well as frequent manicures or use of harsh chemicals, can weaken nails and contribute to the development of ridges.
  • Environmental factors: Exposure to harsh chemicals, such as detergents, cleaning products, or nail care products containing acetone, can strip nails of natural oils and moisture, leading to dryness, weakness, and ridges.
  • Hormonal changes: Hormonal fluctuations, such as those experienced during pregnancy, menopause, or hormonal therapies, can affect nail health and contribute to the development of ridges.

To improve nail health and reduce the appearance of ridges, it’s important to maintain a balanced diet rich in essential nutrients, stay hydrated, avoid excessive exposure to harsh chemicals, wear gloves when doing chores or using chemicals, and practice good nail care habits, such as keeping nails trimmed and moisturized. If weak nails with ridges persist despite lifestyle changes, it’s advisable to consult a healthcare professional for further evaluation and treatment recommendations.
