Common Causes of Brittle and Peeling Nails
Brittle and peeling nails, medically known as onychoschizia or hapalonychia, are a common concern that can affect both fingernails and toenails. While often perceived as a cosmetic issue, they can sometimes indicate underlying health problems or simply be a result of daily habits. Understanding the root causes is the first step toward effective treatment and prevention. The American Academy of Dermatology Association (AAD) [1] notes that brittle nails are a frequent complaint.
The primary causes can be broadly categorized as:
* External Factors (Environmental Exposure): This is the most common culprit. Frequent wetting and drying of the nails, exposure to harsh chemicals, and physical trauma can strip the nails of their natural oils and moisture, leading to dehydration and weakening of the nail plate.
* Internal Factors (Nutritional Deficiencies and Medical Conditions): Less commonly, brittle nails can signal a lack of essential nutrients or an underlying health issue.
Let's delve deeper into these factors.
