🧠 What Causes Brittle Nails?

Understanding the cause is the first step toward fixing weak or fragile nails.

Common causes include:

• Frequent exposure to water
• Harsh nail polish removers (especially acetone)
• Nutrient deficiencies (biotin, iron, zinc)
• Aging
• Overuse of gel and acrylic nails
• Hypothyroidism
• Chronic dryness
• Fungal infections (a hidden cause many people overlook)

📌 Important: If brittle nails also look yellow, flaky, thick, or crumbly, fungus may be involved — even in early stages.

🛠️ How to Fix Brittle Nails: 10 Proven Strategies

1. Keep Your Nails Hydrated (The #1 Rule)

• Jojoba oil
• Vitamin E
• Cuticle oil

2. Use a Strengthening Topical Oil

One of the most effective ways to restore brittle nails is by applying a high-quality topical oil that supports keratin structure and protects the nail plate.

⭐ Dermatologist-Favorite Option: Kerassentials
Kerassentials contains essential oils like tea tree and lavender that help reduce brittleness, peeling, and surface damage.

3. Avoid Excessive Water Exposure

Water causes nails to expand and contract, weakening them over time.

✔ Wear gloves when washing dishes
✔ Avoid long hot showers
✔ Don’t soak nails unnecessarily

---

4. Stop Using Harsh Nail Polish Removers

Acetone strips natural oils and worsens brittleness.

Switch to:

• Non-acetone removers
• Gentle, clean-beauty nail brands

---

5. Keep Nails Short While They Recover

Short nails break less and allow stronger new growth to replace damaged keratin.

---

6. Add Nail-Strengthening Nutrients

Brittle nails are often linked to nutritional gaps.

• Biotin (B7): Improves nail thickness in deficient individuals
• Zinc & Iron: Deficiencies can cause peeling and weakness
• Omega-3s: Improve flexibility and hydration

---

7. Take Breaks From Gel and Acrylic Nails

Long-term gel or acrylic use dehydrates and thins the nail plate.

If you use gels or acrylics:
✔ Take breaks
✔ Rehydrate nails consistently after removal

Many people only notice nail weakness after acrylic removal — this is also when fungal imbalance can begin.

• Peeling
• Brittleness
• Surface cracking
