Think brittle nails are just a cosmetic issue? Not necessarily.
Sometimes, that split or peeling nail may be a deeper message your body is trying to send. What if these seemingly minor signs were actually clues about your overall health? Let’s take a closer look.
Why are your nails becoming brittle?
Think of your nails as tiny indicators of your health. When they weaken, split, or become unusually soft, it’s time to ask the right questions. Often, these annoyances reflect internal imbalances.
1. Nutritional Deficiencies: When Your Plate Betrays Your Nails
Lack of biotin:
Also known as vitamin B8, biotin is essential for strong, healthy nails. A deficiency? The result is soft nails that peel or split with the slightest pressure. To fix this, try adding more eggs, almonds, and sweet potatoes to your diet.
Iron deficiency:
Are your nails spoon-shaped or prone to breaking? A lack of iron may be the culprit. This essential mineral helps oxygenate your cells—including the ones in your nails. Red meat, lentils, and spinach are excellent ways to restore your iron levels.
Not enough protein:
Nails are primarily made of keratin, a protein. If your diet lacks it, your nails will suffer. Include more fish, legumes, or dairy products to help your nails regain their strength.
2. Dehydration: Thirsty Nails
Just like your skin, nails need water to stay flexible and resilient. If you’re not drinking enough, they can become dry, brittle, and prone to splitting. Make a habit of staying hydrated—especially in winter, when dry air can make things worse.
3. Environmental Factors: Invisible Enemies
Harsh chemicals:
Nail polish, strong polish removers, cleaning products… all of these can weaken your nails over time. Use gloves when cleaning, and choose acetone-free nail polish remover to limit the damage.
The weather:
In winter, the cold dries out your nails, while in summer, sun and chlorinated water can cause damage. Hydrate your nails with specific creams and protect them from environmental stressors as much as possible.
4. Underlying Health Issues: When to See a Doctor
Thyroid disorders:
Brittle nails can be a sign of thyroid dysfunction. If this is accompanied by symptoms like persistent fatigue or unexplained weight changes, it’s time to check in with your doctor.
Psoriasis and fungal infections:
Psoriasis doesn’t just affect your skin—it can affect your nails too. Pitting, ridges, thickening… these symptoms are warning signs. Likewise, fungal infections can make nails crumbly and discolored. In both cases, proper treatment is essential.
5. Physical Trauma: Your Nails Are Not Tools!
Do you use your nails to open packages or scrape hard surfaces? These habits can gradually weaken them. Keep your nails trimmed, file them regularly, and avoid rough treatment.
6. Aging: A Natural but Manageable Factor
As we age, nails tend to become drier and more fragile. Don’t panic—by adding omega-3s to your diet (found in fatty fish like salmon) and keeping your nails well-moisturized, you can slow down these effects.
Your nails are silent messengers. Whether it’s a simple biotin deficiency or a more serious health condition, it’s important to pay attention to the signs. By adjusting your diet, taking proper care of your hands, and consulting a professional when needed, you can not only restore your nails’ strength but also improve your overall well-being.
