Brittle nails are a common concern, characterized by nails that easily split, peel, or break. If you’re constantly asking yourself, “Why Are My Nails So Brittle?”, you’re not alone. The good news is that often, the reasons are easily addressed with lifestyle adjustments. Let’s explore the common culprits behind brittle nails and what you can do to restore their health and strength.
The Role of Moisture Balance
One of the primary reasons for brittle nails revolves around moisture – specifically, having either too little or too much. According to the American Osteopathic College of Dermatology (AOCD), moisture imbalances are a leading cause, categorizing brittle nails into two types: dry and brittle, and soft and brittle.
Dry and Brittle Nails: Lack of Hydration
Dry and brittle nails are a sign that your nails are lacking essential moisture. This is frequently due to external factors that strip away natural oils and hydration.
Frequent hand washing and dishwashing are common culprits. Repeatedly wetting and drying your hands, especially without moisturizing afterward, can dehydrate the nail plate, making them hard and prone to breaking.
Environmental factors also play a significant role. Dry climates, low humidity, and winter months, when indoor heating is prevalent, can all contribute to nail dehydration.
Soft and Brittle Nails: Overexposure to Moisture
Conversely, nails can become soft and brittle from excessive moisture. While it seems counterintuitive, too much water exposure can weaken the nail structure.
Over-moisturizing might seem like a solution for brittle nails, but excessive use of hand creams and lotions can sometimes lead to the opposite problem, making nails overly soft and weak.
Harsh chemicals, particularly those found in nail polish removers like acetone, are another significant factor. Acetone is a drying agent that can strip nails of their natural oils, leading to both soft and brittle nail conditions over time.
Other Contributing Factors to Brittle Nails
Beyond moisture imbalances, several other factors and underlying health conditions can contribute to nail brittleness:
-
Anemia (Iron Deficiency): Anemia, often caused by iron deficiency, reduces the body’s ability to carry oxygen effectively. This lack of oxygen can impact nail health, leading to brittle nails and fatigue.
-
Thyroid Disorders: The thyroid gland regulates hormones that are crucial for various bodily functions, including mineral absorption. Thyroid imbalances, whether producing too many or too few hormones, can disrupt mineral absorption, potentially causing nails to become weak and even detach from the nail bed.
-
Aging: As we age, our nails naturally change. They tend to become thinner and weaker over time, making them more susceptible to breakage and brittleness. This is a natural process and a common reason why older adults experience brittle nails.
Identifying the Cause
According to the AOCD, a helpful clue to identify the cause of brittle nails lies in observing both fingernails and toenails. If only your fingernails are brittle while your toenails are strong, it’s more likely that external factors or conditions are the primary cause rather than a systemic health issue.
Seeking Solutions
Addressing brittle nails often involves simple changes to your daily routine. Using moisturizing gloves while doing dishes, applying cuticle oil regularly, limiting exposure to harsh chemicals, and staying hydrated can all contribute to healthier, stronger nails. If you suspect an underlying health condition, consulting a healthcare professional is recommended to determine the best course of action.
